Subsidence, the gradual downward movement of a building or structure, can result in damage to buildings. Keller can apply re-levelling techniques to bring buildings back to their correct levels, strengthen any weak ground under and around the foundations and avoid any recurring settlement.

Underpinning provides additional support to existing foundations that are unable to safely support existing or future loads. Keller can provide the optimal repair or solution to remediate the structure.

It is often desirable to prevent the migration of contamination in the ground, or to prevent seepage from a dam or reservoir. Keller has a wide range of techniques that can be adapted to form an appropriate sealing or cut-off barrier.

Whether natural or man-made soils sometimes present voids that may create sinkholes. Depending on the situation, and the quality of the soils, various techniques can be adapted to provide a permanent solution.

Slope stabilisation is often required to retain soil in a natural, unstable slope or in man-made excavations. Keller draws on its extensive experience with the full range of techniques to provide optimal slope stabilisation solutions for various projects.

Soils often need treating to support the weight of a building or to withstand the loads imposed by a piece of infrastructure. This can mean improving the ground or putting in foundations to transfer the loads to deeper more competent layers.

Keller’s approach to Track Bed Stabilisation (TBS) is ground-breaking and demonstrates our ability to deliver the same technical expertise and innovative quality solutions as we do in every other environment around the world.
