    ​Injection Systems for Ground Consolidation

    Avoid the Unexpected with Pre-Injection 

    Unexpected water ingress and poor ground conditions during underground construction usually escalate costs, can have a negative influence on the environment, and inevitably cause significant delays. To counteract these risks, an economical approach is to pre-inject the ground ahead of the advancing face to avoid water ingress occurring, and to stabilize the ground. Microcements and colloidal silica, the latter also known as mineral grout, allow a cost-effective approach and improve working safety with minimal environmental consequences.​

    Water Stopping 

    Foaming, water-sensitive polyurethanes are ideally suited to combat water ingress quickly and effectively. For particularly difficult cases the solution is a combination of drainage and the injection of a fast-reacting foaming resin. 

    Ground Consolidation 

    Fast-reacting and non-water-sensitive polyurea silicate systems quickly stabilize poor ground. The high-foaming version is excellent for void filling. The less water-sensitive polyurethanes are also suitable to strengthen the ground. 

    Crack Sealing and Concrete Rehabilitation 

    The range of acrylic resins are particularly suitable for rehabilitation injection for cast concrete, segment linings and brick & masonry lined tunnels.​​​
