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.
A secant pile wall consists of overlapping (secant) piles to form structural or cutoff walls and achieve the required water tightness. The design can incorporate steel bar or beams for reinforcement and anchors can provide additional lateral support, if needed.
Dynamic replacement is a variation on dynamic compaction and uses the energy of a falling weight to drive large diameter granular columns into cohesionless soils and fills.
A bridge crossing a body of water creates difficult conditions for the construction of its foundations. Keller can use various techniques to meet the challenges according to the soil, environmental impact assessment, current and water depth.
Keller has the experience and expertise to construct long jetties into deep water to allow the berthing of large vessels without the need for any dredging.
Keller has the engineering capacity to design flexible and tailored wharf construction solutions to meet different soil conditions and requirements.
Screw displacement piles (SDP) and Vibro displacement piles (VDP) are a fast and effective technology for deep, pile foundations for various structures.
This method involves strengthening the ground using high deformation modulus CSC® (Controlled Stiffness Column) concrete displacement columns.
Injection systems involve the injection of aqueous solutions into the ground to treat expansive, collapsible, and desiccated clay and railroad subgrade mud pockets.
Keller designs seal of all types of flood shafts, including structures already in operation and newly designed.
