Dewatering Projects

Before

We have a comprehensive stock of well point dewatering pumps and other equipment as part of our hire fleet.  The area of this excavation measured 80m. x 12m. The natural ground water table was 1.5m.


After

Two dewatering sets were used which ran non -stop for 3 months without any failures.  The ground water table was lowered 3m and remained totally dry during the course of the construction.
