How KIM Can Work For YouA Unique Crystalline AdmixtureKIM is a dry powder that, when added to the concrete mix, forms billions of needle-like crystals that block the passage of water.

It is manufactured by Kryton and is the world’s original integral crystalline concrete waterproofing admixture. KIM eliminates the need for conventional external waterproofing membranes.

Now you know a little more about KIM. Here’s how it can work for you.

Kryton’s integral crystalline waterproofing products are now shipped around the world to answer the needs of architects, engineers, developers and ready mixers.

If you’re an architect, an engineer, a contractor or developer, you know a lot about concrete. You know that concrete is porous and, if it is not waterproofed, water seepage can occur, bringing in water-borne contaminants and chemicals that can cause deterioration. If you want to protect your concrete and ensure your building or structure has a long, serviceable life, you also know that waterproofing is essential.

So what is Krystol Internal Membrane™ (KIM®) and how can it work for you?


The Obama Factor U.S. President Barack Obama took the world by storm during his election campaign, building popularity with his charismatic and easy-going style; his hope and optimism for the future. So when President Obama threw his support behind ‘waterproofing from the inside out’ this past summer, people listened.

The president spoke to the media after hosting a meeting with energy CEOs where they discussed how to create a clean and sustainable future. “When you hear the innovation that’s taking place…that gets you excited about the future,” said President Obama. He described one technology that caught his attention – admixtures that waterproof from within the concrete pores.

Obama told reporters that new concrete materials “last longer and are waterproofed from the inside out, and that can mean that bridges and roads and buildings can last 20 or 30 years longer than using conventional concrete.”

The positive technology endorsement had Kryton’s phones ringing off the hook and brought publicity to a growing sector in the construction world.

How KIM can help Architects and Engineers Ever since Thomas Edison invented and patented the first system of poured concrete architecture, architects and engineers have used concrete to build higher, stronger and better structures. Architects and engineers play a key role in determining the structural design and strength of a building. So their choice of waterproofing material is critical to the success and longevity of a structure.

Kryton’s product KIM offers architects and engineers a reliable, long-term solution to concrete waterproofing problems. First and foremost is effectiveness. Simply put, KIM works. In fact, Kryton’s other waterproofing products, such as Krystol T1 and Krystol Plug, are often called in to repair cracks and leaks when surface applied systems fail. KIM is also effective against hydrostatic pressure – up to 460 ft (140 m) of head pressure – an important consideration on projects such as the Underwater World Aquarium in Melbourne, Australia, where the structure is several storeys below grade and the pilings have to withstand tidal waters. On that project, as on many others, the KIM waterproofing admixture was the sole waterproofer specified. The use of KIM completely eliminated the necessity for other systems and continues to ensure that there’s no water seepage.

Another huge advantage for architects who choose to waterproof concrete with KIM is that uneven forms, irregular corners, outcroppings and other architectural design features can be securely waterproofed. Concrete treated with crystalline admixtures is highly suitable for complex architectural designs.

As architectural protrusions do not pose any waterproofing challenge, any type of concrete structure – vertical, horizontal or shaped – can be securely waterproofed. Externally applied membranes cannot be effectively used in these situations as the sheet membranes are not easily adaptable to unusual angles and uneven surfaces.

Kryton International helps architects and engineers solve the most difficult waterproofing challenges by providing service and support second to none. Kryton sets aside 10 per cent of its worldwide revenues to support its international concrete research laboratories that streamline testing and certification processes on behalf of users and specifiers.

Architects and engineers who choose KIM also know that they’re lowering the cost of waterproofing by up to 40 per cent and shaving weeks off the construction schedule, both important considerations.

What people say about KIM

“As a spec writer, I am always searching for the product(s) that best enhance and reflect the true intent of the architect’s design; the contractor’s ongoing concern for reliability and durability; and the responsibility towards the owner’s need to stay on budget. For years, I have confidently specified Kryton’s KIM to protect the concrete structures where water damage is eminent or possible. This product works as a general waterproofing system for concrete. When a product works then my search is over. Thank you Kryton, for your continuing support and in making my research so much easier.”

How KIM can help Ready Mixers It’s estimated that in the US alone, there are more than 70,000 ready mix concrete trucks on the road, delivering concrete to job sites around the country. The competition is fierce, but ready mixers who know and use Kryton’s Krystol Internal Membrane waterproofing system have the advantage. Not only can they offer an additional ready mix product to contractors and developers, they can increase their profit because KIM-treated concrete has a higher value than regular concrete. Ready mixers with knowledge and experience in Kryton’s products can gain access to new markets and revenue sources without interrupting their normal supply to existing businesses.

Kari Yuers, Kryton’s CEO, explains it this way: “It opens up an entirely new revenue stream by giving them access to waterproofing dollars that would normally go to waterproofing applicators. It puts that money in the pockets of ready mixers.”

Last year Kryton launched the first integral waterproofing certification program designed specifically for ready mixers. Known as KIM Certification, the free program provides assurance to contractors and confidence to ready mix suppliers. Certification verifies that participants understand how to properly and effectively use KIM. “Using KIM and becoming certified gives ready mixers one more tool in their sales arsenal, helping them to maximize their dollars and enhance their reliable and trustworthy reputation,” says Yuers.

For ready mixers, there are other advantages too. Kryton’s labs can assist with mix testing and verification for unusual job sites and situations. The experienced and qualified technical service team can help them deal with any potential issues and offer mix-design advice. And, at the batching plant itself, Kryton has removed any guess work in the ratio of KIM-to-concrete mix. KIM comes in pre-measured, pulpable mixer-ready bags that can be thrown directly into the concrete-mixer trucks.

Going GreenWith Concrete

According to the World Green Building Council,

the world’s buildings and communities are

responsible for 40 per cent of greenhouse

gas emissions into the atmosphere.

Adopting green building

practices can reduce those emissions

by 35 per cent, lower energy use by 30 to 50 per cent, decrease waste output by 70 per cent and reduce water usage by 40 per cent. Given those impacts, it’s no surprise that building green has rapidly become an integral part of the construction industry today.

But can concrete be green?

The answer is yes. Concrete is a viable and sustainable building material that not only extends the life of structures but is now being produced with recycled alternative materials such as reclaimed fly ash. And, waterproofed concrete can also be green.

Using integral crystalline waterproofing rather than external membranes reduces jobsite waste, enables the future recycling of concrete materials and extends the serviceable life of structures – while at the same time keeping water out. It contains no volatile organic compounds, is non-toxic and is safe for contact with potable water.

Now you can make the choice to build structures that serve both people and the environment by using integral crystalline waterproofed concrete.

KIM was the first crystalline admixture to be available in pulpable bags for easy addition to the concrete mixer. And the mixer ready bags are in custom sizes to match your mix design.


How KIM can help Contractors and Developers It’s contractors and developers who create, co-ordinate and control the process of development from beginning to end. They work to improve property and increase its value. In doing so, they take on the greatest risk and therefore need to feel confident in every decision they make. They must rely on research and sound judgment to ensure the best, most economical and profitable use for their property. Kryton’s high quality products provide contractors and property developers with confidence that their decision to use unique crystalline technology is one they can trust. Contractors and developers who use KIM rather than an externally-applied membrane system find that their buildings can actually be constructed with a larger footprint. There is no need to accommodate the extra space that would be demanded for perimeter excavation for membrane applications. KIM-treated concrete can be poured to the full extent of permitted space.

KIM’s pulpable bags are also an advantage for developers and contractors as they reduce waste and enhance the building’s eco-friendliness. And that’s an important consideration if a sustainable building market is in their sights.

Another important consideration is that using KIM allows contractors and developers to save time on the construction schedule, opening the way to incentive bonuses for adhering to contracted timelines and allowing them to move to other projects faster. One less sub-trade, less push back and problems on the jobsite, dedicated field support from Kryton itself – all add up to a clear choice in waterproofing solutions for many contractors and developers.

So the next time you’re faced with a job requiring waterproofed concrete, turn to Kryton for a solution that will work for you.

The Challenge of Blind-Wall Applications

Pouring a concrete wall directly against another wall is called a blind-wall. And anyone who has ever tried to waterproof a blind-wall knows that it is a difficult task. Without adequate access, placing external membranes is a challenge. So why not build your waterproofing into the concrete rather than on top of it and save time, money and space?

Crystalline waterproofing formulas:

Become part of the concrete matrixWaterproof concrete from the inside outEliminate the need for blind-wall membrane applicationsCan be added directly to the concrete mix at the time of batchingAllow you to achieve a larger building footprint and maximize spaceAllow you to backfill soonerReduce the cost of labour as well as the potential for application errors

Choose a waterproofing system that will not only work for the long-term but will make your life easier – and your project more profitable.

Solve difficult design challenges such as blind-wall applications.

Integral crystalline waterproofing relies on microscopic crystals to fill concrete’s pores, blocking the flow of water.

KIM won the “Most Innovative Product” award from the World of Concrete tradeshow in 2003. In addition, KIM was the first concrete admixture to be certified by the International Code Council – Evaluation Service (ICC-ES) as a Chemical Admixture used in Concrete (AC198).

There are some developments and structures that leave a legacy on a city and significantly impact its culture. The Eiffel Tower in Paris. The Opera House in Sydney, Australia. Sagrada Familia in Barcelona, Spain. And soon, Singapore will be changed as the soaring towers of Marina Bay Sands redefine that city.

In 2006, the Singapore government turned to Las Vegas Sands Corp. based in Nevada, USA, to develop and operate an integrated resort that would put the country on the world travelling map.

The goal was simple: enhance Singapore’s status as one of the world’s top travel destinations. But the plans soon became enormously ambitious. Las Vegas Sands Corp. committed to opening the doors in three years to a five-star resort unlike anything in the world. The cost for the development is valued at S$8.0 billion (US$5.7 billion).

When it opens in a few months, Marina Bay Sands will feature three 55-storey hotel towers, crowned by a two-acre SkyPark bridging across the towers 200 metres in the air. The SkyPark offers 360-degree views of the city and the sea as well as 250 trees, swimming pools, restaurants and a night club. The resort will provide guests with jogging paths, spas, gardens and a lotus-inspired Arts and Sciences Museum on

the promontory. If that isn’t enough, Marina Bay Sands will also feature one million square feet of integrated waterside promenade, high-end boutiques, a one-million square foot convention centre with the biggest dining hall in Asia, two 2,000-seat theatres, a casino and a 4,000 car garage.

“The unique iconic design of Marina Bay Sands Integrated Resort and Casino will be a global landmark for Singapore,” says Bradley Stone, president of Global Operations and Construction for Las Vegas Sands Corp. “With this promise comes a challenging engineering and construction process, which we continue to successfully overcome.”

One of the many challenges that faced the team was waterproofing. Not only does Singapore have a tropical rainforest climate known for its high humidity and abundant rainfall, but the complex is also being built on reclaimed land, surrounded by seawater. Any leaks in the foundations, below- grade areas or acres of roof-top park would be disastrous – and costly.

The challenge was to find a sole waterproofing product that could

address the many intricacies associated with such a mega-

project, including all below-grade areas, multiple floors,

tunnels, lift and sump pits and water tanks.

With the eyes of the tourism and

construction worlds watching and billions of dollars

on the line, it was imperative that proven solutions be found.

Marina Bay Sands -An Icon to Last

Did You Know?Suspended 200 metres in the air, the Sands SkyPark is the crowning jewel of Marina Bay Sands Integrated Resort and Casino. The sheer size of the SkyPark is mind-boggling – it is large enough to accommodate four and a half A380 jumbo jets and features a public observation deck, landscaped gardens, swimming pools, restaurants and a night club.

So how would you build something that big and that high in the sky? In October 2009, the construction team began lifting the first 330-tonne steel piece into the air to form a bridge between two of the hotel towers. The process took nearly 24 hours to complete and was one of the highest strand jacking operations ever completed in the world. Since then, another 13 pieces of the SkyPark have been hoisted atop the buildings. The result is a significantly changed skyline for Singapore.

The project’s architects, engineers and contractors considered various waterproofing options – from densifiers to pore-blockers to crystalline formulas – to protect the structure. In the end, they selected Kryton’s Krystol Internal Membrane™ (KIM®) as the best choice. The waterproofing project was awarded to Lee Construction Pte. Ltd., the exclusive Kryton distributor for Singapore, in August 2007.

Kryton’s team knew what they were up against. The construction timeline was very tight and the waterproofing system needed to be easy and quick to apply. Delays to the timeline could lead to unacceptable financial and logistical complications. With the project’s proximity to seawater, the waterproofing system needed to withstand salt water, rain water and significant hydrostatic pressure – the deepest point in the project is 25 metres below grade. Finally, the waterproofing needed to endure for decades without failure.

KIM’s integral crystalline waterproofing technology transforms porous concrete into a permanent, water-resistant barrier. If cracks later form, the incoming water will react with KIM’s dormant chemicals and trigger further crystal growth that will keep the structure watertight. It was just what the project team needed.

Due to the project’s size, the work was divided into “packages” and awarded to nearly a dozen different contractors. Lee Construction oversaw the addition of KIM directly into ready-mix trucks at the batching plant, which streamlined the process and helped to minimize logistical challenges. Because KIM could be added directly to the trucks, on-site application errors were also avoided and the construction timeline was maintained. In all, about half a million kilograms of KIM have been used on the project to transform more than 60,000 cubic metres of concrete – base slabs, suspended slabs, walls, tunnels and water tanks – into watertight barriers.

As the project nears completion, the skyline is already changing and worldwide buzz about the project is building. There is no doubt that Marina Bay Sands will put Singapore on the map as one of the best places to visit in the world and will change the identity of the country forever.

Words like “airy” and “elegant” are not often used to describe hospitals but that is exactly what patients and visitors experience when they visit Norwest Private Hospital in Sydney, Australia – a hospital designed to provide all the bells and whistles of a modern hotel. The hospital caters to a high socio-economic demographic and the majority of its admissions are private patients. Aside from featuring wall-to-wall windows and contemporary décor, it also offers 171 beds, 10 operating theatres, almost 700 car bays and more than 8,000 square metres of strata suites.

Sydney lies in a coastal basin and surrounds Sydney Harbour. It is prone to heavy rainfall and flash floods. The architectural firm, Health Projects International Pty Ltd., recognized the hospital needed not only to look appealing but to be consistently dry for health and safety.

The architects specified a waterproofing admixture as a solution. After considering multiple factors, the development

The complex is built at sea level, with a huge garden located over a suspended slab at the ground entrance level, surrounding a circular pool. Waterproofing the concrete below grade, as well as the ground entrance, pool, garden slab, water reservoir and patio, was essential and demanding. Hani Haddad, the developer and owner of A&H Construction and Development, chose to use Kryton International’s integral crystalline waterproofing system because he had used it before and knew it worked.

Building Water Protection Right into Your MortarKMATM

Construction methods in Southeast Asia, China, the Middle East, Southern Europe and Latin America still depend largely on brick-based construction. Bricks can be manufactured locally and are a fairly low-technology solution to housing shortages and low-rise construction needs in these areas.

But the finished buildings depend on surface-applied sealers for waterproofing, as the bricks and mortar are porous. Masonry mortar that’s not waterproofed against high humidity and rain allows for leaks and seeping. Rendering mortar that’s not waterproofed allows for water damage to the substrate, mold growth and discolouration of the building.

Although they’re often used, sealers are not a permanent solution – chipping and flaking as buildings age. Kryton’s introduction of Krystol Mortar Admixture (KMA)TM into the construction marketplace answers the need for a different solution. KMA offers builders a huge opportunity to reduce cracking, reduce shrinkage and improve water resistance – all with one product.

KMA is a dry crystalline powder added to mortar during mixing. It is used as both a masonry mortar and a rendering on the outside of buildings or for interior wet rooms like kitchens and bathrooms. It is based on Kryton’s trusted

Krystol technology. Like other Krystol products, when added to mortar mixes KMA reacts to form long, needle-like crystals that block the capillary pores and micro-cracks within the mortar, effectively blocking water passage. Not only does KMA reduce mortar’s permeability, should any cracks form in the mortar later, KMA reactivates in the presence of water to re-seal the concrete.

In development in Kryton’s labs, KMA has been improved to ensure increased bonding with the building exterior when added to rendering mortars. KMA’s proprietary formula has also been enhanced to decrease the amount of water in the mortar, leading to fewer cracks in the finished product.

“We’ve tested and refined our admixture specifically to address issues that our customers around the world identified,” explains Kevin Yuers, Kryton’s vice president. “They wanted better adhesion, reduced cracking and increased water resistance – we’ve given them the best product to meet their needs.”

KMA can be used with an existing mortar mix design and applied in the usual fashion. It’s easy to add KMA to the ongoing construction activity and get superior results.

Amid the worldwide economic slowdown, the Chinese economy has been booming, thanks in large part to the government’s US$585 billion stimulus package. The People’s Republic of China has poured billions of dollars into improving its infrastructure, spending a significant chunk of government funds on transportation – express roadways, airport construction and improvements and high-speed railways with target speeds of 320 kilometres an hour.

With China’s transportation network being a key factor driving its economy, it is no surprise that much of the investment over the past couple of years has gone into developing and improving the country’s extensive highway system. China has spent more on its roads since 2001 than it has over the previous 50-year period. In the next 10 years, it is predicted that the number of miles of developed roads in China will overtake that in the United States. Construction has been fast and not always with the best results.

In 2006, as part of a project to create a highway network that would connect all of China’s 31 provinces, the government focused its attention on a superhighway project in Sichuan province, in southwest China. The new expressway was to span more than 180 kilometres and run along the Yangtze River, connecting two major cities: Chengdu, Sichuan’s capital city, and Leshan. The project involved building five pairs of tunnels in a mountainous region of the province. Although the tunnels were completed in early 2007, the soil and rock conditions, combined with heavy seasonal rainfall, quickly led to concrete cracking and subsequent water leaks. Only a few short months after they were built, the tunnels needed to be repaired.

This was no small job. The surface area on the leaking tunnels was more than 125,000 square metres (1.3 million ft2). In addition, the repair location was remote, in the middle of a province known as among the most inaccessible in all of China.

Kryton International learned of the repair challenge and submitted a proposal to the China Highway Authority. Kryton’s team recommended using the Krystol T1 and T2 surface applied crystalline slurry coat system to repair the damaged concrete. The leaking tunnels had been built with cast-in-place concrete and a surface repair was the only solution.

Krystol T1 and T2 is a two-step, surface-applied integral system that prevents water intrusion and repairs cracks while maintaining the existing concrete structure. Krystol T1 contains a high concentration of crystalline chemicals and is the first coat of the system, sealing the concrete against permeating water. Krystol T2 provides a second dose of crystalline chemicals and protects and fortifies the initial

application of T1 as the treatments penetrate the concrete. The system works together and waterproofs the existing structure from the inside. Kryton’s proprietary chemical formula causes millions of needle-like crystals to form when combined with water. Over time the crystals grow and fill naturally occurring pores and voids in concrete, along with the cracks from damage, to provide permanent waterproof protection. Once it’s applied, it takes 28 days for most of the active crystalline chemicals to migrate into

the heart of the concrete, creating a permanent water barrier. At that time, the surface-applied slurry can be completely removed from the face of the concrete, without any effect on its waterproofing abilities.

Many of the crystalline chemicals sit dormant in concrete until the presence of water reactivates them. If water re-enters the concrete through cracks due to shrinkage, settling or seismic activity, the presence of water prompts the crystals to grow again, re-sealing and waterproofing the concrete.

Waterproofing Tunnels in Sichuan, China

Soil and rock conditions, combined with heavy seasonal rainfall, led to water leaks in multiple tunnels that were built in China’s Sichuan province.


This unique ability to self-seal against moisture makes crystalline technology a permanent waterproofing solution that becomes more effective over time and reduces long-term repair and maintenance costs.

About 250 tonnes of Kryton’s products were made in Vancouver, Canada, and shipped to China in the summer of 2007. When they arrived in port, the products were delivered inland by truck and then transferred onto smaller flatbed trucks to navigate the roads to the jobsite in the mountains.

The remote work location required extensive planning. Contractors needed to be able to live onsite for a long period of time. Kryton’s distributor in Chengdu, Chengdu Kaidan Underground Works Ltd., assembled a crew of workers who would live at the remote location for at least 12 weeks. All the workers completed preliminary training in Chengdu as well as in-depth, hands-on training at the jobsite with Kryton staff. It was essential that the workers could be prepared to handle any challenges. They learned how to store and mix materials for the best performance and were taught application techniques, curing methods and best practices.

Before any work could begin, the surfaces in the tunnels needed to be carefully prepared to ensure the best adhesion of the slurry. Dust and other loose particles were removed

from the wall surfaces by using a high pressure washer and additional water was applied to thoroughly saturate the surface. Kryton’s crack repair system was also used to fix large static structural cracks.

Scaffolding soaring six metres high was erected in the tunnels to help the workers effectively apply the slurry. Once the surfaces were prepared, the project team began applying the Krystol T1 and T2 slurry coating. In total, the crews used 250

tonnes of T1 and T2 to waterproof the tunnel walls. Another two tonnes of Kryton’s crack repair system was applied to fix the 1,200 metres of cracked and leaking concrete.

Only 18 weeks after shipping the products to China, the project was finished. It was an ambitious and aggressive timeline for a project this scope and size. The China Highway Authority gave its stamp

of approval on the project completion in late 2007.

On May 12, 2008, less than a year later, a massive earthquake struck Sichuan, killing 90,000 people and injuring 375,000. It was one of the deadliest earthquakes in world history. The earthquake left more than five million people homeless and destroyed entire communities. Despite the devastation all around the region, the newly waterproofed tunnels were not affected. Today, they continue to provide dry and safe passage for everyone who travels China’s southwest superhighway.

Kryton’s team used Krystol T1 and T2, a two-step, surface-applied system, to prevent water intrusion and repair cracks in the tunnel walls.

Efflorescence and contaminants were leaching through the concrete tunnel walls causing deterioration and spalling before Kryton was brought on to help.

A part of the designated heritage district along Hastings Street, the development involves preserving two 1920s-era buildings as well as constructing a new 37-storey, $180-million tower. Kryton was brought on board in 2008 to waterproof all above-grade exposed concrete surfaces. Using Krystol Internal Membrane™ (KIM®) admixture instead of a traditional external sealer gave the development team the multiple benefits of using an integral crystalline waterproofing system, including keeping the natural architectural concrete finish and providing permanent long term protection. In all, 15,000 kilograms of KIM were used to waterproof The Jameson House. The project is expected to be complete in late 2010.

South Health Campus, Calgary, Alberta

Touted as the “future of health care,” the South Health Campus is currently under development in Calgary. Kryton began working on the 155,000 square metre facility in 2008. The development team needed a reliable waterproofing system for the shotcrete water tanks that were designed to catch rain water and feed irrigation systems spread across the 44-acre property. A number of suspended slabs also needed guaranteed waterproofing to protect electrical systems and insulation that were being installed underneath the slabs. The team turned to Kryton as a cost effective and reliable solution that is also compatible with shotcrete application. Approximately 6,000 kilograms of Kryton’s KIM were used on the water tanks while the company’s Krystol Waterstop System was used on the tank joints. Another 9,000 kilograms of Kryton’s Krystol Broadcast – a crystalline concrete waterproofing application with a dye that assists with uniform distribution – were used on the suspended slabs. The first phase of construction is expected to be complete in 2011.

Kryton in CanadaIn spite of a tough economic ride over the last couple years, Canada’s construction industry still employs an estimated 1.2 million Canadians. Of that, 27,000 produce cement, concrete and concrete construction materials. In addition, according to the Cement Association of Canada, cement and concrete sales in 2008 contributed $3.2 billion to Canada’s gross domestic product.

Canada continues to build innovative buildings and infrastructure from coast to coast. With almost four decades of answering Canadian’s concrete waterproofing needs, Kryton has been part of the country’s innovation and success.


Sherbourne Park Water Feature, Toronto, Ontario

Covering almost four acres, Sherbourne Park was designed to be an iconic feature for Toronto. It is located in the centre of East Bayfront, a unique 55-acre neighbourhood, and features a one-and-a-half kilometre water’s edge promenade. Kryton was selected as the waterproofing supplier for the project based on the durability and long-term reliability of its flagship product, KIM. The water feature will be filled with water year round. In the chilly winter months, the water will turn into ice, and, as a result, the structure will face freeze-thaw cycles. More than 12,000 kilograms of KIM were used to waterproof the project and it quickly became the most high profile project Kryton ever completed in Toronto.

Edmonton International Airport Tunnels and Water Cisterns, Edmonton, Alberta

Edmonton International Airport is expecting annual passenger traffic to grow from six to nine million by 2012. When the airport’s management company decided to embark on a massive, $1.1 billion airport expansion project to accommodate that increased traffic, they faced strict deadlines to minimize disruption to service and passenger flow. Kryton was selected to waterproof airport tunnels and water cisterns because of its products’ effectiveness, cost savings and ability to be integrated into the concrete mix off-site. More than five tonnes of KIM have been used to date to waterproof the concrete. The project also called for the use of Kryton’s Krystol Waterstop System to protect joints in the tunnel and cistern walls.

Beaumont Water Reservoir, Nisku, Alberta

Water reservoirs hold water that may eventually flow to taps in your home. So it’s crucial that the water is safe and protected from leaching contaminants. The concrete that surrounds the reservoirs must be reliably and effectively waterproofed. In 2009, Kryton’s products were used to waterproof the Beaumont Water Reservoir in a small community called Nisku, Alberta. The project required a guaranteed defence against water contaminant and leakage. More than five pallets of the surface-applied Krystol T1 and T2 were used on the reservoir.
