Tensar International's Glasstex is predominantly suitable for situations with sustained loading such as that caused by soil swelling tension stresses, frost heave or by temperature induced joint movements.

Glasstex is a composite consisting of bundles of glass filaments stitched onto a polypropylene paving fabric in both the longitudinal and transverse directions using polyester (PET) yarn. The glass fibres provide high tensile stiffness, and the polypropylene fabric provides a means of maintaining the required geometry of the composite, as well as a fixing layer during installation. Once installed and saturated with bitumen, the paving fabric then acts as a waterproofing layer.
