competencies
Everything we do, we do with passion – which is why we do it so well. We are at home on the street, on bridges and buildings, and in corridors, tunnels, and shafts. On the road, we operate with conveyor belts, cranes, and excavators, measuring tape and tables, passion and a great deal of expertise.
Competencies
Injections and waterproofing
We stabilize underground construction sites with sealing as well as cement-bound and chemical injections of gel, synthetic resin, or solid materials. We specialize in underground structures, foundation soils, and excavations for which water permeability is an issue. We are also consulted when there is water ingress during tunnel construction. We are otherwise called on when the following measures need to be taken:
- Waterproofing injections to protect against water in underground structures
- Lifting injections
- Dam injections
- Consolidation and sealing of geological fault zones
- Sealing of excavations in groundwater
- Consolidation injections to improve the load-bearing capacity of the subsoil
- Application and installation of all types of waterproofing membranes
- Liquid or sprayable sealing and coating
- Frost and waterproofing protection
- Special and directional drilling
- Digital injection management
- Control and monitoring management
