Frequently Asked Questions
It is needed when an excavation goes well below the water table, such as deep basements, high-rise foundations, underground parking, bridges and underpasses. It also suits large sites with high groundwater levels or highly permeable soil.
Deep wells can lower groundwater much further than wellpoint systems, which are generally limited to about five to six metres per stage. The achievable drawdown depends on the depth of the wells, pump capacity and soil conditions. A site investigation and system design confirm the exact depth for your project in Abu Dhabi.
Wellpoint dewatering is a groundwater control method that uses closely spaced small wells, a header pipe and a pump to lower the water table around an excavation. It keeps foundations, trenches and pipeline works dry and stable during construction.
The cost depends on the excavation depth and length, soil type, groundwater level, how long pumping is required, power supply and the discharge route for the water. Because every site is different, a price is given after a site assessment. Contact Advanced Dewatering LLC on +971 50 764 6515 for a free assessment.
