Green Roof Water Retention Mat

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.

Green roof water retention mat.

Protection mats can also be used above the drainage system to retain stormwater. Xf drainage mats are engineered to divert excess water from the green roof quickly for healthy plant growth. Moisture retention and protection mat for intensive green roofs. Water storage mat can be used under low slope green roofs to enhance water retention and provide uniform water distribution.

Designed for intensive roof gardens walkways and driveways. Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. The mrm is also a popular choice for fleece based living or green wall systems. Resistant to high mechanical pressure.

The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system. 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. A filter fabric layer on top should separate the aggredrain from the growing media. Made of recycled non rotting polypropylene fibres for water and nutrient retention as well as protection layer.

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. Green roof solutions moisture retention mat mrm protects the waterproofing membrane and holds moisture beneath the drainage layer in green roof systems. Tremdrain gs drainage mats consist of a perforated polystyrene core with fabrics attached to both sides. Mrm is available in two thicknesses 3 16 and 3 8 to suit your project s specific needs.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. Basic uses tremdrain gs is designed to be used in applications such as vegetative roof systems or greenscapes where some water retention is desired.
