We believe no one should be harmed as a result of the work we do or the services we provide. Our ultimate goal is to have zero incidents through the effective management of health and safety in all our operations.
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.
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…
Keller Polska is actively involved in efforts to upgrade infrastructure throughout Poland. Whether it is transportation, railways, tunnels or utilities, we provide geotechnical solutions for each unique project.
Keller is proud to be the world's largest geotechnical specialist contractor and we understand that our success is down to our diverse and talented team, where each individual contributes to our collective achievements.
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 Polska has provided thousands of homeowners, developers and contractors with geotechnical solutions to both large and small residential projects.
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 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.
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.
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 Polska can also measure the impact of…
Ground anchors transfer tensile loads and consist of an anchor head, a free length and a bond length. The free length enables the anchor to be, a big advantage for excavation pits with very low horizontal deflections.
Contiguous pile walls consist of piles arranged in a way that a gap remains between the piles. Where required the soil between the piles can be stabilised during excavation by either installing timber lagging in front of the excavated soil or by building a reinforced shotcrete wall towards the…
Vertical panels are excavated under stabilising slurries using mechanical/hydraulic clamshell grabs or hydromill cutters to form a continuous cut-off, retaining and/or structural wall.
