Green Roof Water Retention Mat

Green roof solutions moisture retention mat mrm protects the waterproofing membrane and holds moisture beneath the drainage layer in green roof systems.

Green roof water retention mat.

Water storage mat can be used under low slope green roofs to enhance water retention and provide uniform water distribution. The mrm is also a popular choice for fleece based living or green wall systems. The highly retentive qualities of this fabric provide a slow evaporative release of moisture for green roof plants from deep in the green roof system. Protection mats can also be used above the drainage system to retain stormwater.

A filter fabric layer on top should separate the aggredrain from the growing media. Mrm is available in two thicknesses 3 16 and 3 8 to suit your project s specific needs. Designed for intensive roof gardens walkways and driveways. Basic uses tremdrain gs is designed to be used in applications such as vegetative roof systems or greenscapes where some water retention is desired.

Resistant to high mechanical pressure. Since three layers of water storage mat will retain approximately one inch of rainfall it can also be covered with a gravel ballast to create non vegetated roofs that reduce and delay stormwater runoff blue roofs. Tremdrain gs drainage mats consist of a perforated polystyrene core with fabrics attached to both sides. Made of recycled non rotting polypropylene fibres for water and nutrient retention as well as protection layer.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. 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. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system. Protection mats are used to protect against mechanical damage and damage during construction and as a base under rigid drainage products and green roof trays.

Moisture retention and protection mat for intensive green roofs. 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.
