The joints of geomembrane fabrics are inevitable during the construction process.

When selecting the anti-seepage geomembrane, we must first establish our ordering purpose, for which place and what function is required for ordering the geomembrane. Knowing this, we can reasonably and effectively reduce the selection category.

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.

Before laying the composite geomembrane, it should go through the inspection of the excavation of the exhaust trench, and complete the finishing and leveling of the bottom and slope of the storage.

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.

The impermeable membrane is non-toxic, odorless, odorless high molecular weight polymer white particles.
