KM22 is our answer to the request for a grout that can absorb earth's pressures and rebound when the earth moves back.
The design can be likened to a castable neoprene sleeve around your tunnel, which absorbs earth movements and reboundes when the earth moves back.
KM Materials was founded to provide innovative materials for tunnels that experience swelling rock or across creeping faults. Answering the question posed to us of developing a grout that will absorb the pressure of rock on sewer tunnels.
Founded by two friends from engineering school KMMaterials combines over 50 years of engineering and materials experience.
Mark Gregory and Kevin Foody have the experience and knowledge to understand the civil and geotechnical issues found in tunneling design.
