GREENFOND Drain TER 4 drainage mat made of hardened polyethylene (HDPE) integrated with water-permeable high-quality geotextile.
GREENFOND DrainTER 4 is designed for versatile use in the field of water insulation protection in vertical and horizontal arrangement. In particular, it is used to drain water from pedestrian paths on garage slabs, extensive green roofs, terraces, foundation walls, bottom slabs, bridge abutments, tunnels, etc.
It can also be used to protect thermal insulation against mechanical damage and constitute an additional supporting waterproofing barrier.
Additionally, it can be used as a waterproofing layer in the construction of concrete structures for roadside drainage ditches and water reservoirs, provided that the layer covering the drainage mat is stable against being lifted by the buoyancy force below it.
