Rapid Impact Compaction densifies shallow, granular soils, using a hydraulic hammer, which repeatedly strikes an impact plate on the ground surface.
Rock grouting is normally done in fissured rock to reduce the flow of water along the joints and discontinuities in the rock.
Low mobility (compaction) grouting involves the injection of a low slump, mortar grout to densify loose, granular soils and stabilise subsurface voids or sinkholes.
Mine or cavity grouting generally uses a low strength cement based grout to fill large natural or man- made voids.
Driven precast piles are deep foundation elements installed using impact or vibration hammers to a design depth or resistance. Keller have developed the design and manufacturing capability over the past 30 years to design piles up to 400mm square and have a fleet of rigs capable of installing…
Franki Piles, also known as enlarged based driven cast in-situ piles, are cast-in-place elements constructed using a drop weight (hammer) and temporary casing. They can provide high capacity piles with relatively shallow installation depths.
Ductile piles are a deep foundation method using the displacement technique with prefabricated piles made of ductile cast iron available in 118 mm and 170 mm diameters with different wall thickness.
As well as open site works these piles have been used in locations that it has been…
Micropiles, also known as minipiles, are small-diameter drilled piles. Micropiles offer a cost-effective and efficient means to overcome a variety of foundation construction challenges.
Bored piles are high-capacity, cast-in-place elements constructed using a conventional kelly bar and auger system. Whether installed as individual foundation elements, in a pile cap group, or a retaining wall, we are ready to provide you with an optimised bored pile solution.
Bored piles are an effective product with many applications in foundation and civil engineering. Temporary and permanent steel casings are used for a number of engineering reasons.
Secant piled walls are a form of embedded retaining wall and can be designed as cantilevered or propped for greater excavation depths. These techniques form a continuous barrier to reduce flow of soils and water through the wall.
Drilled displacement piles are a type of augered pile, however instead of removing the material, the soil is displaced laterally into the surrounding soil resulting in a similar profiled regular shaft pile.
Artificial ground freezing converts in situ pore water to ice through the circulation of a chilled liquid via a system of small-diameter pipes placed in drilled holes.
The Atlas pile is a unique “screw” shaped displacement pile. It is designed to take maximum advantage of all available soil capacity by displacing the soil rather than replacing it. The Atlas pile is a concrete cast in situ pile installed with new generation high torque hydraulic piling rigs.…
Impact rolling compacts the ground through the rotation of a non-circular rolling module delivering insitu compaction with significant densification and strength improvement.
The cased CFA pile is a variation on the traditional CFA pile.
