TECHNICAL NOTE ON EPOXY BONDING OF GEOTEXTILES

In order to transfer stress between geotextile panels the selvage edges are mechanically seamed by sewing. In light-to-medium-strength geotextiles (geotextiles with wide width tensile strengths of up to 175 kN/m (1000 lb/in) it is possible to attain up to 80% efficiency in the final seamed product. Beyond this strength range the sewn seam efficiency is drastically reduced. For applications which require the use of high-strength geotextiles (i.e. soft soil stabilization) a designer is often limited by the seam strength between panels. This paper explores the use of chemical seaming as an alternative joining technique and presents results of a preliminary investigation on the performance of an epoxy resin used to lap seam a high-strength polyester geotextile.(A)
