Blankets/Roof Vegetation Mat II
Roof Vegetation Mat II is a unique solution to age old problems – soil erosion and stabilization of soil on slopes and vegetated drainage channels. Most erosion control products lack ability to keep soils in place until root systems are mature, and have overcome the potential to be undercut by rapid flow of storm water.
Roof Vegetation Mat II is a three-dimensional permanent structure designed to isolate and contain small zones of soil and roots over the slope surface, while at the same time minimizing water disturbance to dislodge soil and roots from above or below the unit.
System Description
Roof Vegetation Mat II units consist of rigid upstanding rings connected with a flexible diagonal geogrid injection molded onto a geotextile fabric. The fabric acts to contain soil or gravel fill, while rows of bars and rings act to prevent erosion channels developing between rows of rings. Generally spunbonded non-woven fabrics made of polyester are injection molded to the ring and grid and used to enhance root system strength.
Roof Vegetation Mat II Benefits
- True 3-dimensional containment to fill.
- Rings and bars offer effective small scale confinement
- Shallow depth of fill material needed
- Strong diagonal grid to disperse loads across slopes
- All units (and rolls) can be interlocked for continuous structure across slopes
- Geotextile fabrics and grid strengthen root matrix.
- Fabrics act to slow speed of water infiltration and reduce chance of undercutting.
- Fabrics under gravel fill can prevent plant penetration from below and resist root penetration from above.
- Product is lightweight and easy to assemble.
- 90% post-industrial recycled plastics resin content.
- Plastics are UV resistant and inert from damage from normal chemicals used in horticulture and biological agents.
