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…
Wet soil mixing, also known as the deep mixing method, improves the characteristics of weak soils by mechanically mixing them with cementitious binder slurry.
Keller UK provides geotechnical solutions for the commercial market sector for both existing and planned structures, including office buildings, hotels, distribution centres, retail, data centres, and other structures.
Continuous flight auger (CFA) piles are drilled and concreted in one continuous operation enabling much faster installation time than for bored piles. Reinforcement is placed into the wet concrete after casting, enabling the pile to resist the full range of structural loading.
This technique involves the improvement of weak soils by the installation of densely compacted columns made from gravel or similar material with a vibrator. The displacement process reinforces all soils in the treatment zone and densifies surrounding granular soils. It’s a technique first…
Keller has teamed up with the University of Surrey to launch a project to explore ways of developing more sustainable geotechnical solutions.
Our people are our most valuable asset. We are committed to creating a work environment and culture that brings out their best and keeps Keller a great place to work.
Rigid inclusions is a ground improvement method using high deformation modulus columns constructed through compressible soils to reduce settlement and increase bearing capacity.
Ground improvement efficiency depends on the stiffness relationship between the soil and the columns. Load from…
Mixed modulus columns, also known as columns with Mixed Moduli, mixed columns or CMM® is a sustainable ground improvement method using high deformation modulus columns constructed through compressible soils to reduce settlement and increase bearing capacity. CMM® is the combination of a…
Dynamic compaction involves the controlled impact of a crane hoisted weight, of around 10-12 tonnes, falling in a pre-determined grid pattern to improve loose, granular and mixed soils and fills.
