       What are the main points of construction quality control during the construction of geomembrane composite with non-woven?During the construction of composite geomembrane, regarding the quality control of construction, what are the control points that need our attention? Taian Hongyuan Geosynthetics Co., ltd. is a composite geomembrane wholesaler. The editor will take you to understand the composite geomembrane together. What are the main points of construction quality control during construction!

       1. When the lake bottom is leveled, stones, branches and all sharp and hard objects need to be completely removed to prevent damage to the composite geomembrane. Due to the large water content of the lake bottom soil, the soft parts should be dug out and backfilled to tamping, and the rubber soil should be dug out and backfilled with 3: 7 lime soil.

       2. The laying of the protective layer must be done with a flat shot.

       3. In order to ensure the welding quality of the geomembrane, the weld surface of the geomembrane should be cleaned. Adjust the welding temperature and line welding speed at any time according to the air temperature, wind direction and wind force; often remove the residue of the geomembrane material adhering to the surface of the rubber wheel of the welding machine and the surface of the hot wedge to keep the surface clean; the substrate must be flat and hard when welding. The seam lap surface must be smooth to prevent the weld from wrinkling.

       4. Do not damage the composite geomembrane when laying the protective layer and filling the anchoring end with concrete. After each process is completed, it must be approved by the site supervision engineer before proceeding to the next process.
