These may not be required if the waterproof membrane is certified as root resistant. Green roof solutions protection mats are specially designed needle punched fleece constructed of 100 recycled polyester and polypropylene fibers. Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. 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.

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. The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. Root barrier lower filter fabric water retention mat upper filter fabric growing medium and sedum. A filter fabric layer on top should separate the aggredrain from the growing media.

The most common root barriers used are thin polyethylene sheets laid over the waterproofing membrane. It protects the waterproofing and the insulation of the green roof.
