Re-levelling structures
Solution

Subsidence, the gradual downward movement of a building or structure, can result in damage to buildings. Keller Polska 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…

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…

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 Polska can provide the optimal heavy foundation solution for your…

Underpinning
Solution

Underpinning provides additional support to existing foundations that are unable to safely support existing or future loads. Keller Polska can provide the optimal repair or solution to remediate the structure.

Containment
Solution

It is often desirable to prevent the migration of contamination in the ground, or to prevent seepage from a dam or levee. Keller Polska has a wide range of techniques that can be adapted to form an appropriate sealing or cut-off barrier.

Mine stabilisation/void filling
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.

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.
