Green Roof Drainage Mat

25mm 1 thickness is standard for thin extensive roofs 40mm 1 5 is recommended for enhanced water storage and drainage on thicker extensive roofs and semi intensive roofs and 60mm 2 5 is available for maximum water retention on intensive roofs.

Green roof drainage mat. Tremdrain gs drainage mats consist of a perforated polystyrene core with fabrics attached to both sides. Enkaretain drain 3111 green roof drainage mat interior and exterior planters enkaretain drain 3111 is one of a new generation of products designed specifically for vegetated roofs. Xeroflor s drainage mats are engineered to divert excess water from the green roof quickly for healthy plant growth. Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30.

Basic uses tremdrain gs is designed to be used in applications such as vegetative roof systems or greenscapes where some water retention is desired. 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. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. Exceptional flow rate and compressive strength xf drain s 3d entangled filament profile design creates a 95 open path in all directions to divert excess water from the green roof quickly. 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.
