7Ensuring Efficiency

QualityOur expertise is mirrored in the way we work.

In more than 115 years of ground engineering experience we have developed numerous tried-and-tested standards. Definitely the most demanding one: We keep questioning even long-practiced workflows. For years we have been organising our processes according to LEAN standards in order to continuously enhance our efficiency and to systematically adapt our service portfolio to our customers’ demands.

In this context an effective management regarding occupational health and safety as well as environmental protection is essential. In both fields we have been applying internationally accepted management systems for years. Hence in 2010 our company was certified by TÜV Rheinland according to DIN EN ISO 14001 (environmental management) and BS OHSAS 18001 (occupational health and safety management).

9Providing Reliability

Teams of expertsThe shortest way from plan to realisation is a well-seasoned team.

Our employees are good, if not the best in this sector. We are proud of them. And we do a lot to make them stay and to facilitate both their professional and personal development.

Further together

Our employees’ qualification, motivation and dedication are vital for our success. Hence we attach great importance to the education and training of all of them, irrespective of their vocation or age. From industrial or commercial to technical career, from intern or trainee to professional: Our internal training programmes provide optimal opportunities for lifelong learning regarding professional, social as well as methodological competencies.

Constructing in a spirit of partnership

A high level of team competence is of cardinal importance at ZÜBLIN Ground Engineering. One reason is that today’s complex tasks can only be solved with a holistic approach and with interdisciplinary foresight. Another reason is that the polarity – contractor on the one hand, client company on the other – has become obsolete. Economical success can only be guaranteed if projects are regarded as common cause. This attitude is the defining feature of ZÜBLIN teamconcept – the partnering model we have successfully been practising for more than 15 years. And our committed employees enthusiastically live up to the ideas manifested in our teamconcept.

Techniques Piles

From largest bored piles to micro-piles – we are equipped for all pile foundation methods. Depending on the subsoil conditions we offer you several economically-efficient alternatives for heavily loaded foundations. Foundation improvement underneath existing buildings with limited working heights is available as well. Moreover we utilise our own inspection tools and we work out reliable optimisation concepts with the help of test piles.

Grout injections

The subsoil can be improved by injecting various environmentally-compatible substances. This technique results in increased stability, mitigated settlement or reduced water permeability of the soil. Especially in the latter case, complex and lengthy water rights proceedings as well as high fees can be avoided, since the ground water is prevented from seeping into the building pit.

As a leading company in the field of grouting ZÜBLIN Ground Engineering contributes to the definition of consistent standards, even at European level. We developed our own measuring and controlling system for compensation grouting to be able to provide our clients with standardised and auditable reports.

Ground freezing

Artificial ground freezing prevents ground water from seeping into the building pit, which is thus stabilised. The freezing of the ground is brought about by pipes inserted into the ground, with a cooling agent circulating through them. The solidifying and sealing effect of the freeze is used, for example, for cross passages in underwater tunnel construction and in the case of remediation to bind highly volatile hazardous substances in the ground.

13Realising Visions

Diaphragm walls

Diaphragm walls can be installed in close proximity to existing buildings serving – also in combination with other methods – as solid retaining walls, as load-bearing foundation elements or as sealing against groundwater. Diaphragm walls are typically used in urban locations with difficult subsoil conditions or for landfill sites or complex infrastructure projects. To be able to meet various individual requirements our portfolio includes all diaphragm walling techniques.

Retaining walls

We offer several solutions for the construction of building pits where there is not enough space for a slope and watertightness is not the primary requirement. Depending on your demands we offer the following types of retaining walls: bored pile walls, reinforced concrete diaphragm walls, sheet pile walls, soldier pile walls, soil nail walls, element walls, combi walls etc.

Ground anchors

Ground anchors are prestressed tension members made of steel strands or steel bars installed into mortared boreholes, serving as temporary or permanent means to transfer high tensile forces into the ground. Ground anchors are used, for example, in pit retaining walls, to protect buildings against groundwater uplift forces, to secure slopes or to transfer the reaction forces during pile test loading.

TechnologiesDam sealing

The restoration of leaking dams serves to protect both people and the environment. To prevent water from seeping through a dyke or dam we employ various techniques. Conventional in-situ sealing methods include, for example, the use of cement, chemical grouting, cut-off walls etc.

A novel, very economical and eco-friendly method is the so-called BioSealing. ZÜBLIN Ground Engineering contributed considerably to paving the way for this innovative technique: through cooperations with research institutes and as pioneer in its successful utilisation.

Immersed tube tunnels

Tunnels play an important role in developing the national and international transport networks. Be it because natural obstacles like rivers, mountains or straits need to be overcome; be it because protected areas or nature reserves can be reached optimally.

ZÜBLIN Ground Engineering is an internationally leading expert on immersed tubes. This technique is based on prefabricated tunnel or foundation elements made of concrete which are floated to the tunnel site and sunk into the river or sea bed.

Technologies Large-scale projects

Large-scale projects with numerous interfaces between several contractors require immense coordination efforts engendering additional risks. Awarding the realisation of the whole project to one contractor only is an economical yet advantageous solution allowing you to minimise such risks.

Especially in highly complex projects schedule coordination and schedule adherence play a decisive role. The initiation of the contract awarding procedures is only reasonable after preceding works have been completed. Hence the construction of large building pits including a foundation slab anchored against uplift forces can bring about significant advantages – not only temporal ones.

ZÜBLIN Ground Engineering has the necessary operational expertise as well as the required personnel and equipment capacities – worldwide. Our highly-motivated employees at our department Zentrale Technik carry out all the planning for projects of any size. This efficient interlinking of planning and realisation guarantees an optimal project progression.

Specialist fields

With highly-qualified employees and state-of-the-art machinery ZÜBLIN Ground Engineering is perfectly equipped for special demands. Directional horizontal drilling is an economical yet environment-friendly way to establish connections over long distances, with the adjoining terrain remaining unaffected. It is the perfect solution if buildings, waters or special objects like nature reserves, airports or railway tracks need to be underpassed.

Where cultural monuments are in the way of construction projects they tend to be completely dis- and then reassembled at another location. Our far more gentle solution: We move the whole structure on special rails. And we also offer complicated underwater tunnel relocations as turnkey service.

Innovations BioSealing

BioSealing is a method to seal subterrestrial leakages in dams, subways, tunnels, building pits or underground car parks. The technique is based on the deliberate stimulation of soil bacteria. In a multi-stage process the bacterias’ growth leads to a sustained sealing of the leakage through clay minerals.

ZÜBLIN Ground Engineering substantially contributes to furthering the development of this innovative sealing method. BioSealing is an economical and eco-friendly alternative to conventional techniques like cement suspension or chemical grouting.

Drill-Pilot

The Drill-Pilot is a high-precision measuring tool for directional drilling and remeasurement of existing drill holes. The Drill-Pilot’s advantage lies in its linkup with our in-house data collection – providing much more measurement data for navigation. A display imparts real-time information on the drilling’s progress. Hence the instrument makes redundant a number of intricate accompanying works quite common to highly demanding projects. Reference holes or the installation and measurement of magnetic loops are no longer required. The probe may be used either during the drilling process or for the precise remeasuring of existing holes. Moreover the Drill-Pilot is insensitive to external influences like magnetic fields or electrical interference.

Geothermics

Scarcity of resources, climate change, growing energy demand: Worldwide efforts to solve future tasks sustainably and with a view to forthcoming generations are increasing. In the quest for finding alternative energy sources geothermal energy is gaining ever more importance. Its enormous potential regarding heating, cooling and energy storage currently is being extended through strong R&D efforts. ZÜBLIN Ground Engineering has a leading role in this field as well. Our deep hole drilling equipment enables us to carry out exploratory drilling for resources as well as geothermal well drilling even in great depths.

19Preparing the Future

Monitoring

Systematic monitoring prior to, during and after a project’s realisation has become an integral part of all kinds of construction works. Diverse measuring instruments convey data (online) regarding deformation, subsidence, water ingress, installation parameters etc., with visual data analysis taking place immediately. This allows our project team to professionally interpret the data and to consider them in the construction process immediately.

Research and development

The great range of ground engineering tasks, processes and technologies provides an opportunity to develop novel ideas and ground-breaking innovations. Viewing this challenge in an integral way offers the chance to influence and shape the developments in other disciplines as well.

The required cooperations go far beyond the corporate units of ZÜBLIN. Together with our national and international R&D partners from leading companies, research institutes and universities we foster and expand important networks. The goal: long-term cooperations in order to optimise existing solutions and to find novel answers to new questions.
