Application

Suitable for structural drainage applications on roofs and podiums requiring vehicular access or high volumes of pedestrian access, including motorised wheelchairs and mobility scooters.

Description

Radmat DM25 is a geocomposite drainage layer ideal for structural drainage applications on roofs and podiums requiring vehicular access or high volumes of pedestrian access, including motorised wheelchairs and mobility scooters. Specially designed to be compatible with structural waterproofing DM25 provides optimum performance over the whole life of the structure.


Consisting of a high strength flexible polyethylene cuspated core with a non-woven geotextile bonded onto one or both sides. The geotextile filters a wide range of materials allowing water to perculate into the core to be efficiently drained away to a discharge point. The geotextile is bonded to the core to ensure that it does not deform into the drainage passages under the load of the backfill material allowing continuity of the drainage void. The single cuspated HDPE core forms a high-performance drainage layer with clear void to allow flow in all directions. The compressive strength and creep resistance properties of DM25 ensures that the core maintains its drainage capacity, even when subjected to compressive loads. DM25 is durable and sufficiently robust to resist the mechanical stresses imposed during installation and throughout the design life. Use of DM25 will eliminate the need for further protection of the waterproofing.


Radmat DM25 is supplied in sheets 50 m long and 915 mm wide.
