Groundworks

Whether you are digging a manhole chamber or excavating the foundations for a nuclear power station WJ has the dewatering solution for you. Groundwork contractors generally favour external perimeter dewatering well arrays to avoid access restrictions within the excavation. WJ has achieved the required drawdown in excavations over 500 m wide using perimeter well systems. Recent examples include an ejector dewatering system used to facilitate the excavation of a 2 km drainage run alongside the M3 motorway, and a deepwell & wellpoint combination for the groundworks at the Royal Hospital for Sick Children in Edinburgh. WJ has a range of plant and equipment ready to meet your needs whatever the scale of your excavation.
