What We Do
A specialist geotechnical contractor who combines industry-leading equipment and technology for the design and construction of piled foundations and embedded retaining walls. Since its inception in 2005 the company has grown to become one of the industry’s leading installers of Continuous Flight Auger (CFA) and Rotary Bored piles within the UK working closely with network rail and London Underground.
To maximize our clients specifications we retain a versatile fleet of CFA, Cased CFA and Rotary rigs capable of installing piles from 300mm to 2400mm up to 70m deep. This coupled with our in-house design capability means we can offer detailed and viable value engineered proposals.
Furthermore our competences go beyond piling and, unlike many traditional contractors, we operate our own ancillary plant to facilitate our works and all aspects of sub-structure construction which include installation of Working Platforms, Pile Caps, Capping Beams and Bulk Excavations.

Piles are employed to transmit building loads to a suitable bearing strata, they primarily act in compression but can also cater for horizontal and upward loads.
There are four types of Piling methods we use, Click on the buttons below to view a more detailed illustrative diagrams.
Rotary boring techniques methods employ the use of a temporary casing to seal the pile bore through water-bearing or unstable strata overlying suitable stable material. Upon reaching the design depth, a reinforcing cage is introduced, concrete is poured in the borehole and brought up to the required level, the casing can then be withdrawn. In some cases there may be a need to employ drilling fluids in order to maintain a stable shaft. Rotary auger piles are available in diameters from 300 mm to 2400 mm or even larger and using these techniques, pile lengths of beyond 50 metres can be achieved.
A continuous flight auger (CFA) pile, is formed by drilling into the ground with a hollow stemmed to the required depth. Concrete is then pumped down the stem of the auger while it is slowly withdrawn forming a concrete pile to ground level. CFA piles have the benefit of not requiring any temporary casing ,cause minimal disturbance, and are often used for noise and environmentally sensitive sites.
By installing piles in a line at close centers forms an embedded retaining this will allow an open excavation. Piled walls typically are either Contigous or Secant depending on the ground conditions.
Contiguous Bored Pile Wall
The piles may be constructed so that they virtually touch each other (contiguous).
Secant Bore Pile Wall
Similar to the contiguous bored pile method however piles are installed such that the overlap to form a seal to limit water entry into the subsequent excavation.
