Earth retention and shoring involves retaining soil subjected to either a natural, unstable slope or a man-made excavation and when required, supporting existing adjacent structures.
Keller provides design and constructs services for near-shore marine structures. The advanced capabilities of our in house engineering and construction teams ensure we provide cost-effective, fit-for-purpose, award-winning solutions. Our range of marine piling and ground engineering techniques…
Wet soil mixing, also known as the deep mixing method, improves the characteristics of weak soils by mechanically mixing them with cementitious binder slurry.
Compensation or fracture grouting is the injection of a cement slurry grout into the soil creating and filling fractures that then lift the overlying soil and structures.
Driven cast in-situ (DCIS) piles are constructed by driving a closed-ended hollow steel or concrete casing into the ground and then filling it with concrete.
Keller provides geotechnical solutions for both existing and planned structures, including office buildings, hotels, distribution centres, residential development, commercial establishment, data centres, and other structures.
Continuous flight auger (CFA) piles are a type of bored cast-in-place replacement pile. Piles are drilled and concreted in one continuous operation enabling much faster installation time than for other piles of this type. Reinforcement is placed into the wet concrete after casting, enabling the…
Permeation grouting, also known as cement grouting or pressure grouting, fills cracks or voids in soil and rock and permeates coarse, granular soils with flowable particulate grouts to create a cemented mass.
Vibro compaction is a ground improvement technique that densifies clean, cohesionless granular soils with a downhole vibrator. It’s a technique first developed by Keller in the 1930s that we’ve used on thousands of projects since.
This technique involves construction of loadbearing columns made from gravel or crushed stones with a vibrator to reinforce all soils in the treatment zone and densify surrounding granular soils. It’s a technique first developed by our company founder, Johann Keller, that we’ve used on thousands…
Keller provides systems and services for monitoring the safety and stability of buildings, excavations, bridges, railways, roads, tunnels, dams, embankments and slopes.
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.
Keller’s broad product portfolio means our engineers have more options when it comes to an effective and efficient designs for our clients.
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.
Rapid impact compaction densifies shallow, granular soils, using a hydraulic hammer, which repeatedly strikes an impact plate on the ground surface.
Low mobility (compaction) grouting involves the injection of a low slump, mortar grout to densify loose, granular soils and stabilise subsurface voids or sinkholes.
Driven piles are deep foundation elements installed using impact or vibration hammers to a design depth or resistance.
