Precautions for Geomembrane Construction
The construction work of the anti-seepage project is very important. Assuming that it is used for anti-seepage, what are the precautions before and after construction? Based on my many years of experience, I have summed up a few precautions before and after the construction of the wholesale HDPE geomembrane.
Preparation before laying
1. Foundation treatment: sweep the geomembrane laying surface, and ask for basic flatness, the soil is solid, and can not be uneven, cracks, etc. There should be no sharp objects, stones, iron wires, wood sticks, etc. The turf and tree roots within the impervious range should be cleared, and weeds should be sprayed with herbicides.
2. Lay a sand or clay layer with a small particle size as the protective layer in contact with the film. The thickness of the protective layer should not be less than 30cm.
Welding quality control With the stoppage of construction, we beg to check the quality of the composite HDPE geomembrane factory price and film welding in time and use the plastic welding gun to repair the leaked and virtual welded parts at any time. There is no good way to do this. In most cases, it is a visual inspection to see if the two welds are flat, clear, no wrinkles, transparent, no slag, bubble leaks, melting points or weld seams.
