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.
Keller is actively involved in efforts to upgrade infrastructure throughout Algeria. Whether it is transportation, railways, tunnels or utilities, we provide geotechnical solutions for each unique project.
Why work for us?
We pride ourselves in having some of the best professionals and skilled people in the industry who are motivated by our culture and the opportunities for career growth.
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. Whether an open site or inside an existing structure, Keller can provide the optimal heavy foundation solution for your project. This…
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. [Company] 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 [Company] can also measure the impact of the…
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…
King post/soldier piles and lagging walls are a cost effective system of temporary or permanent retaining wall using beams and pre-cast concrete panels.
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.
Sheet piling retains soil, using steel sheets with interlocking edges and is applied using both vibratory and vibration-free installation rigs.
During construction it is often necessary to form a stable excavation and to ensure that any associated movement will not damage neighbouring structures or utilities. Keller offers flexible solutions to solve even highly complex excavation support problems both in a temporary or in a permanent…
