Stabilising and draining reservoir foundations
The soils supporting geomembrane sealing systems must be stable and drained to prevent any damage.
Draining bases, drainage trenches, facing membranes and trench drains can be executed easily and quickly with a needle-punched nonwoven composite with a network of mini-drains: teradrain®.

Draining gases
The air contained in soils is due to their organic fermentation, or air being pushed by groundwater rising.
To prevent this air from accumulating and pushing the waterproofing system upward, forming swellings and making the reservoir unfit for storage use, a network of de-gassing strips – separate from the water drainage network and connected to vents, is executed with needle-punched nonwoven composite with a network of mini-drains: teradrain®.
