THE PROBLEM:
During the construction of a water ponds, flows of underground water and water tables can be intercepted, wich must be drained to eliminate the hydrostatic pressure and guarantee the stability of the structure.
THE SOLUTION:
The fitting of INTERDRAIN below the waterproofing allows:
1. interception of underground flows.
2. Lowering the water table.
3. Cutting capillary ascents in clayey and loamy soils.
As INTERDRAIN protects the geomembrane, it is not necessary to fit heavy protection geotextiles.
