Abstract

Method and means for producing an erosion control blanket formed from wood wool fibres retained in a coherent structure with a biodegradable mesh to be secured on a soil surface to ameliorate erosion of that surface and provide a basis for plant regrowth which will subsequently bind the soil surface.

Claims

1. A soil erosion control blanket, comprising a mat of wood-wool fibers retained in a coherent structure by means of a biodegradable mesh such that at least some of the fibres interlock with the mesh and others of said fibres.

2. An erosion control blanket as claimed in claim 1, wherein said mesh is of plastics material.
