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…
Polavaram dam is one of India’s most high-profile national infrastructure projects, designed to direct essential water for crops, communities and hydropower. It’s also a fantastic example of Keller’s ability to collaborate and transfer technologies to offer our clients a truly exceptional…

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.
Micropiles, also known as minipiles, pin piles, needle piles, and root piles, are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars.
Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering.
Keller designs and constructs cost-effective build or design-build geotechnical solutions for the industrial and manufacturing sector.
Keller has wide experience of provide the energy sector with cost-effective solutions to ground problems.
Keller can provide solutions for the full range of institutional structures including government and military, education, healthcare, and sports and entertainment.
