Drainage mats transport liquids (or gases) outside the construction or towards places where they can be treated in an appropriate manner.
By draining water away quickly and efficiently, the mats help reduce the hydro-physical stress the lining layers in the substructures are exposed to.
In earth constructions they eliminate the saturation of construction layers and thus help them maintain their design parameters in the long term.
When installed in waste disposal site restoration projects, the mats prevent the accumulation of waste gases under the sealing layer enabling its controlled treatment.
At the same time, they can be used for detection of leakage, or for transporting leachate away from the waste body.
Key properties of drainage mats:
Tensile strength - EN ISO 10319
Elongation - EN ISO 10319
Water flow capacity in the plane - EN ISO 12958
