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

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…

/expertise/solutions/seepage-control
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…

/expertise/solutions/heavy-foundations
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.

Mine stabilisation / void filling
Solution

Unstable ground can cause instability both in the temporary and permanent case. We have a range of solutions that can be deployed to strengthen the soils.

/expertise/solutions/mine-stabilisation-void-filling
Sinkhole / Karst stabilisation
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.

/expertise/solutions/sinkhole-karst-stabilisation
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…

/expertise/solutions/excavation-support
Heave control
Solution

When wet soils swell and can’t expand downwards or sideways, the soil rises up and exposes the upper surface, effectively the opposite of subsidence. While displacement may be relatively small, ground heave can still lead to serious structural damage. Keller can provide the best solution to…

/expertise/solutions/heave-control
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.

/expertise/solutions/remediation
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.

/expertise/solutions/slope-stabilisation
Ground improvement
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.
