New Build

Wentworth

Following a rigorous and lengthy tender process, Alert Piling Solutions Limited were appointed as the specialist contractor by the property developer, to construct a new build domestic dwelling in the highly prestigious Wentworth Estate, Virginia Water, Surrey.

Our works involved initially with assessment of the overlying ground and instructing the developer to provide an adequate piling mat due to the soft ground conditions. Following on from this, we then installed 64 No. heavy wall tubular piles to depths of upto 13.0m to achieve the required SWL of upto 475kN. Upon completion of the piling element, 268Lm of 450mm x 500mm reinforced concrete ground beam were constructed above ground level and shuttered using the proprietary Pecafil system.

The final element of our works was to lay the underbuild brickwork / blockwork and to design and place 155mm deep beam & flooring to the entire dwelling footprint.

All works were completed in 5 weeks (On time and within budget)
