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 cohesive 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 the country. 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.
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.
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 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.
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.
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, or Soilcrete, of varying geometries in the ground.
Get to know the leaders who guide our business strategy, deliver our projects, and ensure we maintain our high standards of safety, sustainability, and innovation.
Unstable ground can cause instability both in the temporary and permanent case. We have a range of solutions that can be deployed to strengthen the soils.
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…
