erosion control blanket iGGmat strawcoir

There are different types of the classic erosion control blanket made of straw and coir in the iGGmat strawcoir product series. They all have a fiber layer of straw and coir and are stitched either on one or both sides with a backing made of PP-netting or jute fabric, as well as a PP- or jute-fiber. All iGGmat strawcoir products can also be supplied as seeded blankets. In this case a carrying paper with seeds is stitched to the fiber cover.

iGGmat strawcoir is used on areas at risk of erosion with up to 20° slope (1:2.7) for temporary erosion control. The lifetime of the iGGmat strawcoir is up to 24 months. It depends on the conditions of the location, the soil, water and climatic conditions as well as the risk of erosion on-site. iGGmat strawcoir products are up to 100 % biodegradable.

Use

Placing the iGGmat strawcoir is done on a prepared and, if necessary, seeded area. The erosion control blanket must lie completely flat on the soil with no cavities. The individual strips must be placed perpendicular to the slope of the embankment, next to each other over the entire area. Overlapping on the vertical longitudinal joints should be about 10 cm and on the transverse joints about 10- 20 cm. The open edge of the overlap must be away from the predominant wind direction. Transverse joints must basically overlap from top to bottom. The top and bottom ends of the erosion control mat must be dug into the top and bottom of the slope approx. 10–20 cm deep and fastened afterwards. Fastening is done using iGGfix U-shaped fixing pins or iGGfix wooden fixing pins.
