Green Roof Water Retention Mat

Ccw miradrain gr9400 is a high capacity retention drainage composite with a three dimensional high impact polypropylene core for use on horizontal green roof.

Green roof water retention mat.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. 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. Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. 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.

Moisture retention and protection mat for extensive green roofs and ballasted roofs. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system. Green roof solutions moisture retention mat mrm protects the waterproofing membrane and holds moisture beneath the drainage layer in green roof 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.

Xf drainage mats are engineered to divert excess water from the green roof quickly for healthy plant growth. Bitumen resistant biologically and chemically neutral heat resistant. The mrm is also a popular choice for fleece based living or green wall 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. Reinforced sheet membrane and hot applied liquid waterproofing system. It looks like a rolled up blanket. A filter fabric layer on top should separate the aggredrain from the growing media.

Made of recycled non rotting polyester fibers for water and nutrient retention as well as a protection layer. This picture shows water retention matting just before kev to installed it on to this green roof in london. Water storage mat can be used under low slope green roofs to enhance water retention and provide uniform water distribution. 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 highly retentive qualities of this fabric provide a slow evaporative release of moisture for green roof plants from deep in the green roof system. Basic uses tremdrain gs is designed to be used in applications such as vegetative roof systems or greenscapes where some water retention is desired. 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.
