Abstract
Abstract A turf product for use in erosion control is provided as a turf product matting of a fibrous material in combination with a reinforcing mesh for giving directional stability thereto. Turf is located above the matting and the reinforcing mesh with its root system passing thereinto. The turf is initially grown above the matting and the reinforcing mesh with its root mass passing therethrough onto an impervious surface. The impervious surface acts as a barrier to root transmission, so that the roots tend to mat above the impervious surface, and when the turf product is moved to its required location for use, the roots are then permitted to pass into an underlying surface.
