ABSTRACT:
A flexible clay liner in roll form for use on steep slopes. The liner includes a layer of geotextiles. The geotextiles are stitched together in rows of stitches which extend along the length of the liner. The thread used to make the stitching is a multifilament thread treated with a resin to prevent wicking through the liner. The spacing of the rows of stitches and the frequency of stitches along the rows are sufficient to transfer shear stresses through the bentonite layers, thus preventing the bentonite from becoming a shear plane.
