Green roof systems incorporate several layers in addition to the waterproofing membrane.
Green roof aeration layer material.
The design creates an open and continuous flow path even under high loads.
Root barrier the root barrier is the system that avoids the membrane underneath from being pierced and penetrated by roots ensuring that the system can remain.

A roof garden system is a roof area where plants or a landscape is installed above a waterproofed substrate.
The basic anatomy of a green roof consists of vegetation growing medium filter membrane drainage layer waterproof root repellant layer roofing membrane support for plantings above thermal insulation vapor control layer and structural roof support.
Older green roofs often used a permeable layer of rock aggregate such as scoria or gravel for drainage.
The filter layer separates the substrate layers growth media from the drainage layer below and captures the humic particles and organic materials from draining out leaving them for the plants.
Grs extenduct is a 40 recycled drainage core in a waffle pattern with a geocomposite fabric bonded to the top side.
It consists of a waterproofing system and its associated components such as a protection course root barrier drainage layer thermal insulation and aeration layer and an overburden of growth medium and plantings.
The filter fabric top layer prevents clogging from the growing media and the waffle entanglements sit directly on the root barrier.
Drainage protection filtration layer it is used for lightweight green roofs terraces and has many functions.

9 500 psf compression 30 gal min ft flow rate 1 1 gal 10 sqft retention.
The clay and silt content of materials used in a rock aggregate drainage layer should be 10 per cent by mass.
Functional components include a root barrier drainage layer separation layer moisture resistant insulation aeration layer moisture retention layer reservoir.
Features polypropylene core 100 recycled filter fabric.
It is made of a filtration veil and the polyamide monofilament fibre network layer.
All three types of roofs require specific layers of roofing materials not found on regular roofs.
Growing medium is the foundation for your plant growth and depending on the types of plants you want to have on your green roof the depth of the soil.

Grs extenduct 2 includes an additional geocomposite fabric bonded to.
