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.
Dry soil mixing is a ground improvement technique that improves soft, high moisture clays, peats, and other weak soils, by mechanically mixing them with dry cementitious binder.
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.…
Keller is actively involved in efforts to upgrade infrastructure throughout Norway. 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.
Liquefiable soil does not mean a site has to be abandoned, or that heavy foundations are required. Keller can apply a number of cost-effective techniques to mitigate liquefaction.
Keller has provided thousands of homeowners, developers and contractors with geotechnical solutions to both large and small residential projects.
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.
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…
It is often desirable to prevent the migration of contamination in the ground, or to prevent seepage from a dam or levee. 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. The free length enables the anchor to be, a big advantage for excavation pits with very low horizontal deflections.
Single bore multiple anchor (SBMA) are ground anchors with multiple (more than one) bonds.
