Strengthen your soil and foundation with precision injection solutions

Soil is the foundation of any construction project, especially in geotechnical engineering, tunnelling, and underground infrastructures. However, soil conditions are often unpredictable, leading to issues such as settlements, seepage and soil collapse. Conventional solutions to these problems are typically invasive, costly and increase the issues by adding higher specific weight to the already weak system. We offer a comprehensive injection system for soil injections to achieve different targets. Each system contains the appropriate injection resin, equipment and if required and on-site technical support. Read more below or contact us for more information.

Challenges of unstable soil

person
Settlements of foundations, slabs, roads, and railways

Foundations and concrete surfaces are the base of our structures. Settlement can lead to stability issues and restricted use. By using the right injection method, you can secure the intended use of the structure.

Stop Water Ingress with Professional Injection Solutions

Water ingress can occur in many different ways - whether it's a gushing leak in a diaphragm wall, a broken seal in a tunnel segment joint or a leaking expansion joint. Identifying the right method and choosing the right injection system to deal with water ingress is a complex challenge that requires a technical and well-planned approach. Rely on our decades years of experience and on our proven injection methods and materials that effectively stop water ingress.

Challenges of water ingress
