INTROD/CTION TO PVC WATERPROOFING MEMBRANES

PVC (polyvinyl chloride) roof membranes have the longest track record of any

thermoplastic membrane, with the first PVC-based systems installed in Europe in the early

1960s. The use of PVC waterproofs membranes for under ground structures ( even challenging

structures like canals, Tunnels, etc. ) continues to grow in the recent years all across the globe.

Besides the important feature of heat-welded seam technology, PVC waterproof membranes offer

many other inherent features.

PVC# A 0i%t+," + p,+,m'1

Specifically, vinyl is polyvinyl chloride. PVC is a molecule comprised of carbon, hydrogen

and chlorine (taken from salt). As mentioned above, todays reinforced and non reinforced

plasticized poly vinyl membranes have a long history of installations worldwide; many that were

installed over 30 years ago , are still performing today. Vinyl membranes for roof and under

ground structure applications were first developed in Germany and Switzerland in the 1960s and

arrived in North America in the 1970s. The use of vinyl membranes has grown significantly and

rapidly in North America ever since then. In Asian market too, the technology has got its

successful footings quite a long time back in countries like China, Japan etc. However, as far as

Indian market is concerned, the technology is still in its initial days and Sika is proud to pioneer

that effort with a vast experience in the field with already few major projects undertaken on Indian

soil.

Vinyl is the best known thermoplastic roof membrane. Thermoplastic means that when

heated sufficiently, the material temporarily changes from a solid to a semisolid state

enabling the sheets or panels that are overlapped to be fused together and return to a

solid upon cooling, yielding one continuous membrane. It is this feature that enables the

seam overlaps of vinyl roof membranes to be fused or heat welded together.

To accomplish the welding, specialized, electrically-powered welding equipment that is either self-

propelled or handheld is used. These units operate on electricity and inject heated air into the

seam area, softening the membrane surfaces. A roller that is either hand-held or part of the selfpropelled unit, presses the seam overlap together. As the welder moves away from a given seam

location, the membrane quickly cools down to ambient temperature and the heat weld is made,

providing a watertight bond.

Vinyl roof membranes are manufactured by various methods, including extrusion,

calendering, laminating, extrusion coating, spread coating or a combination of the above.

In all cases, however, the finished vinyl roof membrane contains polyester or fiber glass

reinforcement, vinyl resins, ultra-violet light inhibitors, heat-stabilizers, biocides, pigments

and plasticizers. Polyester reinforcement imparts high tearing and breaking strengths

needed for mechanically- fastened roofing systems.

The versatility of vinyl affords the membrane manufacturer many options when formulating

for enhanced chemical resistance, flexibility and/or tensile strength. Vinyl membranes

have great versatility of application. Vinyl membranes are usually mechanically attached, adhered

to the substrate . In addition, vinyl membrane can be readily produced with fleece cushion

backing (typically polyester) that enables it to be installed over slightly rough surfaces and/or to be

adhered with a variety of adhesives.

In order to complement this versatility of application, vinyl roof membranes can be

manufactured in a variety of colors. This feature allows for the application of rooftop logos

or multiple-color roofs. The look of steep slope metal can also be simulated with a coloredvinyl membrane.

Another significant benefit of Poly vinyl waterproof membranes is their fire resistance. Vinyl

membranes are inherently self-extinguishing which enables them to perform exceptionally well in

fire tests undertaken at organizations such as Underwriters Laboratories and Factory Mutual, etc.

and to perform reliably in real-world flame exposure. In addition to fire resistance, vinyl

membranes also meet or exceed other industry performance standards that involve water

leakage, puncture resistance, root resistance and so on.

Over a long period of time, vinyl roof membranes have earned the recognition of being a

proven and versatile thermoplastic for under ground waterproofing applications.
