DANODREN H15 PLUS | HDPE dimpled drainage membrane with geotextile

Drainage

Description

With a pre-bonded geotextile and 1,907 cones per square metre — a dense distribution of supports at a height of just 7.5 mm. A brown, high-density polyethylene (HDPE) sheet that combines drainage, mechanical protection of the waterproofing and filtration in a single layer, without the need for a separate geotextile.

The difference from a standard sheet lies in the geotextile: as it is bonded directly to the cones themselves, it absorbs and filters ground water before it reaches the drainage void. Consequently, the 5.9 l/m² void does not become clogged with fine-grained material, and the flow rate is maintained over time — the primary point of failure in unfiltered systems.

It withstands a compressive strength of 180 kN/m² ±20% and a tensile strength of 15.0 kN/m in both directions. Weight: 615 g/m² (500 g HDPE + 115 g geotextile). It bears the CE mark in accordance with EN 13252 and the voluntary AENOR quality mark. It is manufactured from 100% recycled material (20% pre-consumer + 80% post-consumer) at the DANOSA factory in Fontanar, Spain, which is certified to ISO 9001 and ISO 14001.
