Roots are described growing through the mat and 30–40 cm into the ground, so that mat, grass and soil become one cover. Before the grass is up, the mat is there to keep seed in place and to break the energy of wind and water.
A black mat is described absorbing heat and extending the growing season. Once vegetation is established, the brochure says the cover can stand high water and fast flow. The velocities in that sentence are not clear enough to quote.
The mat can also be filled or covered with concrete, asphalt or riprap for a permanent face on roads, railways, rivers, dams and hillsides. On sand, it is described as a way to hold a dune.
What the brochure emphasises
- About 90% void space for fill and roots.
- Holds seed on a slope before germination.
- Can be combined with a hard armour layer.
Uses named in the brochure
- Vegetated slopes on roads, railways, rivers and dams.
- Sand dunes and bare ground that needs a rougher surface.
