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…
Keller UK has provided thousands of homeowners, developers and contractors with geotechnical solutions to both large and small residential projects.
Weak, compressible soils may require loads to be transferred through to underlying competent soils or rock. Whether an open site or inside an existing structure, as one of the UK's leading piling companies Keller can provide the optimal piling solution for your project. This 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.
At Keller, we are committed to better understand our contribution to sustainable development and work collaboratively with our customers and stakeholders to reduce potential impacts.
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.
Jet grouting uses high velocity fluid jets to construct cemented soil of varying geometries in the ground.
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 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…
Ground anchors transfer tensile loads and consist of an anchor head, a free length and a bond length. Anchors can offer an advantage for basements and large excavations by minimising horizontal deflections.
Single bore multiple anchor (SBMA) are ground anchors with multiple strands, each bonded to the soil/rock and carrying a load.
Contiguous pile walls consist of piles arranged in a line typically with a 150mm gap between the piles. Where required the soil between the piles can be stabilised using grouting techniques if necessary, either before or after pile installation.
King post walls are a cost-effective system of temporary or permanent retention using beams and precast concrete panels.
Slurry walls are constructed using a cement-bentonite slurry to produce a below ground low permeability barrier.
