Wellpoint dewatering system is the most efficient form of dewatering. It is used to lower ground water level and to provide the stable and dry working conditions needed for perfect basement excavations.
Wellpoint systems are capable of dealing with various ground conditions ranging from silty, fine sands to coarse sands and gravel. A single stage Wellpoint system can achieve a drawdown of upto 6m deep. Alternatively, for deeper excavations, a second stage of Wellpoints can be installed or a deep well system can be used. Wellpoint is installed by using a steel tube and a high pressure jetting pump together.
