Heave control
Solution
Heave control 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…

Re-levelling structures
Solution
Re-levelling structures 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…

Ground improvement
Solution
Ground improvement 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…

Liquefaction mitigation
Solution
Liquefaction mitigation 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
Seepage control 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…

Sinkhole / Karst stabilisation
Solution
Sinkhole / Karst stabilisation 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…
