A porous, reinforced, erosion control matting is provided by a relatively open, self-supporting, three-dimensionally looped structure of synthetic filaments having a diameter of at least 0.06 mm., with a backing of a decay-resistant or rot-resistant, comparatively dense web or fabric which is bonded to at least some of the filaments of the matting, and with a lattice or open-mesh reinforcing facing member extending parallel to the backing to provide an upper surface of crossbars onto which the looped synthetic filaments are laid so as to be interlocked with the crossbars while extending downwardly between the crossbars to form porous alveolate cells. The matting is highly useful in preventing soil erosion while also being easily manufactured and installed in any given location.

A porous, reinforced, erosion control matting which comprises: an open-mesh reinforcing lattice or crossbars defining an upper facing side of the matting; a plurality of continuous, melt-spun, substantially amorphous, synthetic polymer filaments having a diameter of at least about 0.06 mm., said filaments being laid onto and interlocked with substantially all of the crossbars of said lattice in the form of longitudinally and transversely overlapping loops of intermingled filaments bonded at random points of intersection and extending downwardly from said lattice to form porous multi-walled alveolate cells between the crossbars in a self-supporting, three-dimensional, looped structure; and a soil-retaining, fibrous backing member defining a bottom facing side of the matting arranged approximately parallel to said lattice and at a distance therefrom sufficient to receive at least several millimeters of soil, at least part of the filaments being bonded to said backing member.
