The geomembrane product is generally composite and is a kind of artificial synthetic material with good anti-seepage effect. The geomembrane is laid on the slope surface that needs anti-seepage treatment. The sand cushion or concrete is laid on it, and the concrete layer is sealed on the top of the embankment to form a closed overall anti-seepage system.
The geomembrane is a composite form of two cloth and one film. The laying is divided into two parts: channel bottom laying and slope laying. The laying method is rolling along the channel axis. The slope laying is rolling along the slope axis, and the geomembrane at the channel bottom is connected in a T-shape.
The construction of geomembrane should be carried out in dry and warm weather environment. The splicing of geomembrane adopts hot melt welding method. The welding quality directly affects the seepage prevention effect of geomembrane.
