ON SITE SEWING OF GEOTEXTILES

In order to save the expense of overlapping, geotexiles are joined by sewing. The seam's tensile strength should be as close as possible to the tensile strength of the geotextile fabric; with high performance (hp) fabrics this may be difficult to achieve. Seam strength is a function of: fabric tensile strength, fabric type, stitch type, seam type, thread types, stitch count (stitches per inch), needle size and type, thread tension, weakening of thread due to heating of needle by friction. The author gives advice on selection of sewing equipment, site preparation, movement of fabric and placement, preparation for seaming, sewing. Heavy duty sewing heads making U.S. Federal standard stitch type 401 are usually required on heavy hp fabrics. The sewing machine can be suspended from a boom carried by a truck or tractor. Advice is given on back filling over the fabric after sewing to avoid damaging the fabric and seams. (TRRL)
