Drain mats are used for restraint of erosion in the surface of the soil, thus protecting against a collapse of the slope.
The “drain mat method” has 3 characteristics of erosion restraint:
Firstly, the non-woven fabrics promptly drain off excess existing water, and flocculants aggregate soil particles on the soil surface.
Secondly, the growth-media pouch, in a convex shape, reduces the momentum of water flow on the ground surface.
Thirdly, the growth-media pouch contains fertilizer and water-holding materials that allow for the rapid growth of plants.
Material used on the net is – PE,
Material used on felt: PET nonwoven fabrics
Usage: Embankments and cut slop (strong acidity, alkalinity and rocks are excluded)
