As clean water becomes more expensive to acquire, it produces the need for secure water containment and transport. As time passes by, concrete-lined canals may crack, resulting in a considerable loss of water. Earthen canals also have the erosion and leakage problems.
Geomembrane canal liners may be left exposed or may be protected with a covering layer of soil or concrete. The protective concrete layer may be cast-in-place with reinforcing steel, pumped into geotextile forms, precast in panels or spray applied.
Our YINGFAN textured geomembranes can improve concrete stability during its placement on slopes by increasing the friction between the liner and the concrete and the liner and the subgrade. YINGFAN HDPE/LLDPE geomembrane lining is a quite effective and economical solution to canal leakage and erosion problems. To reach better leakage prevention technical efficiency, bentonite GCL and nonwoven geotextile can be applied together with geomembrane.
