Geomembrane welding refers to the connection of two or more geomembranes by thermal welding to form a continuous and airtight seam. This ensures that the geomembrane is completely sealed during application and provides effective anti-penetration and anti-leakage properties. Geomembrane welding usually uses hot melt welding technology. Five steps for geomembrane welding Preparation: Unfold the geomembrane

Geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. The geomembrane has dual functions of waterproofing and preventing plant roots from penetrating, and can withstand the puncture of plant roots and has waterproof functions. Creates a waterproof layer that is highly resistant to pressurized water and puncture-resistant.
