 Combination Construction of Jiantong Geotextile and Geomembrane on Site


Our client selected both geotextile and geomembrane for their anti-seepage project, which is under construction now.

In the construction, the geotextile above the geomembrane is naturally overlapped, and the upper geotextile of the geomembrane is welded by seam or hot air. Hot air welding is the preferred method of connecting filament geotextiles. That is, the connection between two pieces of cloth is instantly heated at high temperature with a hot air gun, so that part of it is melted, and immediately using a certain external force to make it firmly bonded together.

In the case of hot (rainy or snowy) weather when hot-stick bonding cannot be performed, the geotextile should adopt another method-a suture connection method, that is, a double-thread suture connection with a special sewing machine, and a chemical UV-resistant suture line.

10cm smaller width when stitching, 20cm smaller width when natural overlap, and 20cm smaller width when hot air welding.

For seams, use sutures of the same quality as geotextiles, and use sutures that are more resistant to chemical damage and UV light.

The geomembrane is laid after the geotextile is approved by the site supervision engineer.
