What should we pay attention to when constructing anti-seepage membrane?
Before laying, the geomembrane should pass the acceptance of the foundation surface. Only after passing the test can it be laid. Ensure that the paving surface is flat and no unevenness is allowed. Roots, stones and other hard objects on the paving surface should be removed, and all hard objects such as roots and stones should be removed from the paving surface. If there is water accumulation, the geomembrane should be laid vertically and horizontally. The number of membrane materials to be laid should be calculated according to the channel area. The cut membrane material should be 5% larger than the actual area. The seams should be hot-melt welded. The seams should be spliced on site. Each welding The seam overlap length is 10cm. Before geomembrane welding, the welding surface must be cleaned. There should be no oil or dust on the welding bead and the overlapping surface must be kept dry.
