Re-levelling structures
Solution

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 sinking issues.…

Liquefaction mitigation
Solution

Liquefiable soil does not mean a site has to be abandoned, or that heavy foundations are required. Keller can apply a number of cost-effective techniques to mitigate liquefaction.

Underpinning
Solution

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.

Heavy foundations
Solution

Weak, compressible soils may require structural elements, specifically heavy foundations, that transfer loads through to underlying competent soils or rock. Whether an open site or inside an existing structure, Keller can provide the optimal heavy foundation solution for your project. This…

Containment
Solution

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

Mine stabilisation/void filling
Solution

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.

Tunnelling
Solution

Tunnelling projects require a variety of solutions to make them safe to construct whilst minimising the impact on the surrounding infrastructure. As well as providing mitigating solutions to prevent instability, water ingress and protection measures, Keller can also measure the impact of the…

Excavation support
Solution

During construction it is often necessary to form a stable excavation and to ensure that any associated movement will not damage neighbouring structures or utilities.  Keller offers flexible solutions to solve even highly complex excavation support problems both in a temporary or in a…

Slope stabilisation
Solution

Keller draws on its extensive experience with the full range of techniques to provide optimal slope stabilisation solutions for various projects.

Bearing capacity / settlement control
Solution

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.
