Description

Root Barrier Membrane & Separation Layer

The Green Roof Root Barrier Membrane protects your primary waterproofing layer and structure from roots when installing a green roof. 

The high-quality plastic membrane creates a physical barrier between the green roof vegetation and the waterproofing later. Manufactured from 100% polypropylene, the membrane is designed to prevent root penetration. The non-woven green roof barrier material is also designed to be tear-resistant and not breakdown due to alkalis, acids, organic solvents and electrolyte attack. 

Uses of Root Barrier

This green roof root barrier is suitable for both pitched and flat, intensive and extensive systems. Intensive roofs usually require a root protection and separation layer to protect from mechanical damage during the ongoing upkeep and maintenance of the living roof.

Separation Layer 

The root barrier membrane is suitable as a separation layer for use in single-ply green roofs, intensive roofs and under domestic driveways.

A separation layer (sometimes known as a slip layer) allows the waterproofing layer and overall structure to move independently of the green roof. 

Installing a Root Barrier as part of a Green Roof System

Once a primary waterproofing layer has been applied to the concrete roof deck or screed, you can roll out the root barrier membrane across the length of the roof. Cut the barrier membrane to size. It is possible to overlap and tape the barrier. You can now install the drainage membrane layer on top.
