Dewatering Methods for Dewatering Excavation at
Jan 24, 2019 · Dewatering during excavations is required at construction sites generally for foundation works. Dewatering of any excavated area is done in order to keep the excavation bottom dry so that excess water does not weaken the concrete or wash away cement. The excavation or laying foundation in the waterlogged ground is a very tough activity.

Construction Dewatering | Aquatech Dewatering
Deep wells are typically used to dewater excavations from 6 m/20ft to 30m/100 ft deep, but we have and can dewater to depths of as much as 300m/1000ft without staging. Electrical submersible turbine pumps can be selected based on depth and volume of water that needs to be pumped, solar powered pumps can also be used in some dewatering applications.
