Groundwater Lowering Method

This construction method (deep well, well point) is also generally referred to as the forced dewatering method. It places casing and other structures in the ground into which it forcefully collects groundwater that is drained and filtered. Through this it is able to lower the level of groundwater.

Groundwater Lowering Method


  • Blocks groundwater from seeping into the excavation area, which makes excavation easier.
  • Stabilizes the excavation slope and prevents it from becoming muddy or crumbling and breaking.
  • Compacts the base of structures and roadbeds and improves soil quality.
  • Reduces the soil pressure during temporary support and soil retaining works.
