Green Roof Water Retention Mat

The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system.

Green roof water retention mat.

Designed for intensive roof gardens walkways and driveways. Tremdrain gs drainage mats consist of a perforated polystyrene core with fabrics attached to both sides. Green roof solutions moisture retention mat mrm protects the waterproofing membrane and holds moisture beneath the drainage layer in green roof systems. Water storage mat can be used under low slope green roofs to enhance water retention and provide uniform water distribution.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. 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. Xf drainage mats are engineered to divert excess water from the green roof quickly for healthy plant growth. Basic uses tremdrain gs is designed to be used in applications such as vegetative roof systems or greenscapes where some water retention is desired.

Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. Protection mats can also be used above the drainage system to retain stormwater. 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. A filter fabric layer on top should separate the aggredrain from the growing media.

Allows rainwater to water vegetation in green roofs without waterlogging the plant xf is highly permeable geo composites that combine drainage filter aeration and water retention functions in one product. Made of recycled non rotting polypropylene fibres for water and nutrient retention as well as protection layer. Moisture retention and protection mat for intensive green roofs. 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.

The mrm is also a popular choice for fleece based living or green wall systems. 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.
