Laiwu treatment of geotextile composite geomembrane manufacturers introduced geomembrane seams seams deal is a key step, the direct impact on anti-seepage effect. General seams ways are: ① lap: lap width should be greater than 15cm; ② heat welding: suitable for thicker geomembrane base, weld lap width of not less than 5CM (not recommended glued, soaked in water for a long time. easy to open plastic, impervious poor results.) joints Note (1) seaming geomembrane construction program is the key to directly affect the operational life of the project, according to quality testing showed that the thermal welding method is ideal. (Also available special adhesive bonding) PE Geomembrane heat welding method is heat treated in contact with the surface, so that surface melting, and then get together to make it through the pressure, (2) the laying of geomembrane best in a certain direction, geomembrane both sides have set aside a certain PE film and PET does adhesive layer laying geomembrane to adjust to each unit in order to two units geomembrane welding. (3) geomembrane laying, use sand bags to hold him down, to wind action, the edge seams request can not have dirt, moisture and dust. (4) Before welding seams to adjust the two side PE single film, so that a certain degree of overlapping broadband and smooth, wrinkle-free. (5) When welding, the best technical staff have some experience of welding, welding using special welding machine for welding. To adjust the temperature and speed, (also adhesive bonding). Shandong Laiwu Materials Co., Ltd. based on years of proven, geomembranes thickness not less than 0.25mm, too thin may have holes, and easily damaged during construction and reduce seepage effect. Geomembrane construction, laying particular attention to do not too tight, can not fight wrinkles, stitching to secure. In strict accordance with the technical specifications of construction, the good preparation, laying, splicing, testing and backfilling five quality.
