geocomposite material Manufacturers

When overlapping with the adjacent composite geomembrane, first expose the geotextile at the joints, sew the adjacent geotextile of the lower layer, adjust the welding edge of the two membrane layers, and weld the middle of the composite geomembrane with an overlap width of 150mm body.

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.

Leebo 1.5mm hdpe geomembrane sheet is widely used in various anti-seepage systems. It has three basic characteristics required in various environmental protection fields:

Before laying the composite geomembrane, the excavation and inspection of the exhaust trough, the cleaning and leveling of the bottom of the warehouse and the inclined surface must be completed.
