Green Roof Water Retention Mat

Designed for intensive roof gardens walkways and driveways.

Green roof water retention mat.

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. Mrm is available in two thicknesses 3 16 and 3 8 to suit your project s specific needs. Moisture retention and protection mat for intensive green roofs.

Tremdrain gs drainage mats consist of a perforated polystyrene core with fabrics attached to both sides. 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 systems of this type are drained by a multi layer fabric mat called a drainage mat that combines soil separation drainage and protection functions. 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.

A filter fabric layer on top should separate the aggredrain from the growing media. Resistant to high mechanical pressure. The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. Protection mats can also be used above the drainage system to retain stormwater.

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

Made of recycled non rotting polypropylene fibres for water and nutrient retention as well as protection layer. Green roof solutions moisture retention mat mrm protects the waterproofing membrane and holds moisture beneath the drainage layer in green roof systems.
