Liquefaction mitigation
Solution

Liquefaction is a common problem in earthquake-prone areas where soils lose strength due to the ground motion and behave like a viscous liquid, damaging overlying structures.

Seepage control
Solution

Major civil engineering schemes often involve working below the water table. Controlling or preventing water seepage is vital to allow construction to proceed. Keller has a range of techniques to deploy to provide effective cut-offs and to seal joints and fissures in the ground or below ground…

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.

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 permanent…

Remediation
Solution

Increasing land shortage is driving a need to use more brownfield and marginal land often requiring groundwater and soil remediation to reduce contaminants. Keller is the ideal partner for remediation projects, offering the optimal solution to make contaminated land suitable for re-use.

Slope stabilisation
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.

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.
