Our vegetative roofi ng fi lter fl eece’s design is integral to having a successful vegetative roof. This is realized through ample pore space in the fl eece to prevent it from clogging; thus preventing anaerobic soil conditions. It is also this same design that prevents the fi ne particles of growth media from compromising the underlying drainage / retention boards. We attain these qualities through geo-textiles that are produced from a rot proof polypropylene thread that uses a needle felting method.

Our SI & Intensive Filter Fleece is used when the drainage system needs to be protected from fi ne particles entering from the substrate layer. Specifi c to this product, it:

acts as a separation between vegetation areas and vegetation-free zones

is designed with the necessary elasticity to allow for the more aggressive root structures of semi-intensive plant species to penetrate it

enables plants to uptake water from the drainage / retention board while maintaining the fl eece’s fi ltration capacity

separates drainage and substrate layers in multi-layered structures
