GSE was called upon to line the newly constructed Pasto Grande Umarzo Canal project in the mountains of Peru. The concrete-lined canal measures 59,000 feet (18 km) and supplies drinking and irrigation water to an agricultural community.
We used a geotextile cushion and our textured HDPE waterproofing geomembrane to line the canal. A steel-reinforced, cast-in-place concrete protective covering was later installed over the geomembrane to minimize the cost of the surface preparation and to protect the HDPE. Forms were utilized on the steep side slopes.
GSE textured geomembrane was an excellent choice for this difficult and demanding canal lining installation. It proved able to withstand the installation of the protective concrete layer and continues to hold up well under traffic.
