摘要

Loose fleece in the form of mats for reinforcing and reducing erosion of dams, dykes, slopes, canal bottoms and the like, contains at least one layer of synthetic fibres, such as polyamides, polyesters or polyalkanes, these fibres being naturally bonded by welding, or by an adhesive resistant to seawater and chemicals. - The fibrous mats are useful for reinforcing and reducing erosion of dams, dykes etc. The mats are light weight, have a high strength, good flexibility, and their loose structure enables plants to grow between the spaces.
