ND X20 Drainage System

High-quality, CE-marked drainage system with water reservoir for roofs with extensive vegetation. The approximately 20 mm high drainage system prevents the build-up of hydrostatic pressure against the waterproofing membrane, protects it against mechanical loads and ensures that water vapor from the XPS insulation can evaporate freely in an inverted roof. This drainage system consists of a filter geotextile, perforated drainage core and pressure-dividing protective geotextile.

Long product description

High-quality, CE-marked drainage system with water reservoir for roofs with extensive vegetation. The approximately 20 mm high drainage system prevents the build-up of hydrostatic pressure against the waterproofing membrane, protects it against mechanical loads and ensures that water vapor from the XPS insulation can evaporate freely in an inverted roof. This drainage system consists of a filter geotextile, perforated drainage core and pressure-dividing protective geotextile.

Easy to transport

The rolls can be moved by just 1 person to the right spot (by hand truck or by simply rolling). The rolls are immediately ready to install.

Easy to roll out

We supply our ND Drainage Systems as rolls. This means, that all three required system layers – protection layer, drainage layer and filter layer – are unrolled at once in one motion.

Fast to install

Unroll, overlap and done. Since all layers are glued together, delays due to wind effects or wrongly positioned layers are nearly impossible. It can’t be quicker.

Rock & roll
The ND Drainage Systems are easy and quick to install because the filter, drainage and (sliding and) protection layer are glued together. The ND Drainage Systems are supplied as rolls, making them easy to handle and quick to unroll.

Glued, not thermally bonded
The filter, protective (and slip) layers are glued and not thermally bonded to the core of the dimpled core. This prevents damage to the mechanical and hydraulic properties of the geotextiles and the entire drainage system. It also prevents that geotextiles form being pressed between the dimples, which could jeopardize good drainage. The overlap of the filter geotextile ensures optimal filtration.
