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.

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 levee.  [Company] 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.

If a construction project needs to monitor structural or ground movement or environmental properties like temperature, noise or vibration, [Company] can design and install an instrumentation scheme, provide the software that gathers the information and present it in an easy to use format.

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 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.
