Polyurethane grouting involves injecting expanding polyurethane to fill and seal cracks, voids, and re-level slabs.
Driven piles are deep foundation elements installed using impact or vibration hammers to a design depth or resistance.
Franki piles, or pressure-injected footings (PIFS), are high-capacity, cast-in-place elements constructed using a drop weight and casing.
Helical piles, also known as helical piers or screw piles, are constructed using steel shafts with helical flights of various sizes to suit site-specific ground conditions.
A macropile® is an ultra-high-capacity micropile typically drilled in place.
Shotcrete can create a natural-looking surface covering sculptured, textured, or stained while wet to blend in with the environment.
Secant or tangent piles are columns constructed adjacent (tangent) or overlapping (secant) to form structural or cutoff walls. From soil mixing to drilled shafts, we draw on our complete suite of techniques to optimize the design and construction of these walls.
Vibro concrete columns involve constructing concrete columns with a bottom-feed, down-hole vibratory probe to transfer loads through weak strata to a firm underlying stratum.

GEO-Instruments, a Keller affiliate, provides geotechnical and structural monitoring services. These services help owners, infrastructure operators, and construction engineers identify and mitigate risk, optimize designs and methods…
Slope stabilization is often required to retain soil in natural, unstable slopes or man-made excavations. Keller draws on its extensive experience with the full range of techniques to provide optimal slope stabilization solutions for various projects.
Soils often need treatment to support the weight of a building or to withstand the loads imposed by a piece of infrastructure. This can mean ground improvement or installing foundations to transfer the loads to deeper, more competent layers.
