Canal liners are installed through a series of steps designed to ensure proper coverage and durability. First, the canal bed and sides are prepared by clearing debris and leveling the surface. This is essential to create a smooth foundation for the liner. If using concrete, the area is often graded, and reinforcement materials like steel rebar may be placed before pouring the concrete.
For geomembrane or geotextile liners, the material is unrolled along the canal, carefully positioned, and secured in place, often using anchors, weights, or mechanical fasteners. The edges are then sealed, either by welding, gluing, or using a combination of both methods, to prevent water from seeping under the liner. In some cases, additional layers, such as a geotextile fabric, are used underneath to provide support and filtration. Once the liner is installed, it is tested for leaks and adjusted if necessary.
