Up to 50 percent of irrigation water never reaches farmland, mostly because it seeps from the irrigation ditches while flowing to the fields. A geotextile/polyurethane elastomer composite developed by Innovative Process Corp. and Bayer’s Polyurethanes division overcomes many of the shortcomings of traditional lining materials, and is a valid solution for lining deteriorated concrete or dirt ditches.

The key difference between this new composite liner and other geomembranes is that the geotextiles soaked with polyurethane resin are applied wet. This means the composite liner can anchor itself to the concrete and adheres to itself in the overlapping portions. The result is a seamless, permanent flexible liner that will retain water, and will neither crack nor tear.

Mobile equipment is used to mix and apply the polyurethane binder on-site.
