Polyurethane/geotextile composites
The polyurethane/geotextile composite liner consists of two layers of geotextiles, imbedded in a solid, yet flexible continuous matrix of polyurethane elastomer. The resin is a specially formulated hydrophobic polyurethane elastomer that, combined with the geotextiles, forms a strong composite with excellent physical properties. Preferred geotextiles for the application are inexpensive, nonwoven, polypropylene or polyester fabrics. The thickness of the polyurethane/geotextile composite can be tailored according to the application requirements. The wide variety of commercially available geotextiles and the possibility to vary the material thickness on the lining machine makes it possible to adjust the polyurethane/geotextile composite for application in earthen as well as broken concrete canals. The single composite is well suited for the lining of deteriorated concrete canals, and double sheets are strong enough to be used as lining material for earthen canals. The key difference between the polyurethane/geotextile composite liner and geomembranes is that the geotextiles soaked with the liquid polyurethane resin are field fabricated and applied wet. This means that the wet composite liner can anchor itself to the concrete or any other substrate it is applied on. The polyurethane/geotextile composite liner as presented in this paper is a viable solution for the renovation of earthen and concrete canals.
