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.
Green roof aeration layer material.
Older green roofs often used a permeable layer of rock aggregate such as scoria or gravel for drainage.
Green roof systems incorporate several layers in addition to the waterproofing membrane.
A roof garden system is a roof area where plants or a landscape is installed above a waterproofed substrate.
Grs extenduct is a 40 recycled drainage core in a waffle pattern with a geocomposite fabric bonded to the top side.
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.
It is made of a filtration veil and the polyamide monofilament fibre network layer.
Features polypropylene core 100 recycled filter fabric.
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.
Grs extenduct 2 includes an additional geocomposite fabric bonded to.
Drainage protection filtration layer it is used for lightweight green roofs terraces and has many functions.
The design creates an open and continuous flow path even under high loads.
Structural deck primer waterproofing membrane protection course root barrier drainage layer moisture resistant thermal insulation aeration layer moisture retainage layer reservoir layer filter fabric or geo textile a combination drainage layer and filter fabric and an engineered soil based growth medium with plantings.
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.
All three types of roofs require specific layers of roofing materials not found on regular roofs.
Also the green roof drainage layer material is made to be sturdy and strong so that piercing can be limited and that the integrity of the entire program can be retained with ease.
Protection drainage and filtration.
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.
The rock aggregate should also have a suitable ph and be low in soluble salts to ensure plant growth is not adversely affected.
4 wide x 50 ft roll.
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.
The filter fabric top layer prevents clogging from the growing media and the waffle entanglements sit directly on the root barrier.
