Proven Dewatering Experience

Our team of engineers, designers and project managers have over 150 years of experience delivering dewatering and water treatment solutions on high profile projects across a broad range of sectors.

Wellpoint dewatering overcome significant challenges in Bedford.

The redevelopment project in Bedford involved multiple subsurface excavations situated below the groundwater level. PDL devised and executed a wellpoint dewatering system to efficiently manage groundwater, allowing for dry excavations while concurrently improving the soil’s shear strength.

WELLPOINT DEWATERING TO ENABLE BULK EXCAVATION IN CHELMSFORD

In order to facilitate the development of five new dwellings and two basements, a perimeter wellpoint system was designed and implemented. Due to the anticipation of high inflow rates, PDL had to ensure that the dewatering system was fully capable of handling the task. To learn more about this project, click on the heading above.

BASEMENT DEWATERING IN GREATER LONDON

PDL is currently busy with 3 no. basement dewatering projects in the Greater London. Each project presents unique challenges, such as limited site access and difficult soil conditions, but we have successfully implemented appropriate dewatering strategies in all cases.
