Green Roof Protection Fabric

The most common root barriers used are thin polyethylene sheets laid over the waterproofing membrane.

Green roof protection fabric.

Root barriers are often used in green roofs to provide some protection to the waterproofing from invasive stolons rhizomes and from woody roots from trees and shrubs. Root barrier lower filter fabric water retention mat upper filter fabric growing medium and sedum. Green roof solutions protection mats are specially designed needle punched fleece constructed of 100 recycled polyester and polypropylene fibers. Green roof systems of this type are drained by a multi layer fabric mat called a drainage mat that combines soil separation drainage and protection functions.

Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system. Green roof components can include. These may not be required if the waterproof membrane is certified as root resistant.

The roofing base assembly and a vegetated roof system. It is able to absorb 3 6 l m moisture depending on the product. Compared with green roofs systems using drainage plates or granular drainage this system is the fastest to install and creates the thinnest and lightest green roof assembly. A filter fabric layer on top should separate the aggredrain from the growing media.

Our protection mats are multifunctional products which are compatible with multiple membranes for use as a first layer of protection on the waterproofing membrane or above the root barrier. This geotextile is made of polyester fibres a mixture of mechanically reinforced fibres and regenerated polyester and polypropylene.
