Green Roof Water Retention Mat

Mrm is available in two thicknesses 3 16 and 3 8 to suit your project s specific needs.

Green roof water retention mat.

Basic uses tremdrain gs is designed to be used in applications such as vegetative roof systems or greenscapes where some water retention is desired. 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. 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. 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.

Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. Tremdrain gs drainage mats consist of a perforated polystyrene core with fabrics attached to both sides. Designed for intensive roof gardens walkways and driveways. 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.

Made of recycled non rotting polypropylene fibres for water and nutrient retention as well as protection layer. 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. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system.

Xf drainage mats are engineered to divert excess water from the green roof quickly for healthy plant growth. Resistant to high mechanical pressure. Moisture retention and protection mat for intensive green roofs. 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.

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.
