Our U.S. fabrication facilities are fully stocked and prepared to meet any deadline with high-quality, custom-made solutions.

Our state-of-the-art fabrication facilities across the U.S. have a fully stocked inventory and can meet the most demanding project deadlines. We can provide custom panel sizes of the various geomembranes to meet your design specifications or provide you with one of our prefabricated in-stock products. Using the latest in heat fusion technology, our fabricators can manufacture large panels quickly and get it delivered to your job site.

Taking certain steps in the fabrication process can help your project progress more smoothly when on the job site. For example, fabrication of flexible geomembrane liners eliminates up to 80% of field seaming – resulting in less construction time. Seaming the liners in a climate-controlled factory setting also eliminates weather issues, such as contamination from dust, dirt, water, wind, and site debris, which can cause early wear-and-tear to the geomembranes.
