Smart systems for green and utility roofs

This high-quality plastic film protects a non-root-resistant waterproofing membrane from damage caused by root penetration from extensive vegetation (ND WSB-50) and intensive vegetation (ND WSB-80). Tested for root resistancy.

ND WSB-80 Root Barrier
37.5 m x 4 m
150 m², roll
approx. 0.8 mm
approx. 748 g/m²
low density polyethylene (LDPE)
black

Installation

The root-barrier sheet is laid loose on top of the waterproofing membrane that is not root-resistant. The overlap should be at least 100 mm and has to be heat-welded with a heat gun. The heat gun should be adjusted to the optimum temperature for LDPE foils. In general, the recommendations of the manufacturers should be followed. We recommend a welding temperature of 265/280 degrees.

Tested

Determination of resistance to root penetration according to hEN EN 13948:2007.
