​Injection Systems for Ground Consolidation

Unexpected water ingress and poor ground conditions during underground construction can escalate costs, negatively impact the environment, and cause significant delays. To counteract these risks, an economical approach is to pre-inject the ground ahead of the advancing face to prevent water ingress and stabilise the ground. Microcements and colloidal silica (also known as mineral grout) offer a cost-effective solution that improves safety and minimises environmental impact.

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 is particularly suitable for rehabilitation injection for cast concrete, segment linings and brick & masonry lined tunnels.​​​
