Welding of impervious geotextile
1. Seam processing is the key to the construction process, the general use of heat welding method, PE film surface heat treatment, so that the surface melting, and then through the pressure, so that one fusion. 2. For the laying of a good geomembrane, edge seams require no oil, water, dust and so on. 3. Before welding to adjust the seam at the two sides of the PE single film, so that a certain width of the lap, lap width is generally 6 ~ 8 cm and smooth, no wrinkles. 4. Use special welding machine for welding. Welding construction effect map:
