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.
Jet Grouting uses high velocity fluid jets to construct cemented soil of varying geometries in the ground.
Ground anchors transfer tensile loads and consist of an anchor head, a free length and a bond length. The free length enables the anchor to be, a big advantage for excavation pits with very low horizontal deflections.
Contiguous pile walls consist of piles arranged in a way that a gap remains between the piles. Where required the soil between the piles can be stabilised during excavation by either installing timber lagging in front of the excavated soil or by building a reinforced shotcrete wall towards the…
Vertical panels are excavated under stabilising slurries using mechanical/hydraulic clamshell grabs or hydromill cutters to form a continuous cut-off, retaining and/or structural wall.
Slurry walls are constructed using a cement-bentonite slurry to produce a below ground low permeability barrier.
Sheet piling retains soil, using steel sheets with interlocking edges and is applied using both vibratory and vibration-free installation rigs.
