HDPE geomembrane in the anti-seepage construction quality inspection method 1: laying anti-seepage membrane should be civil engineering corresponding to the corresponding acceptance of documents. 2: anti-seepage film before cutting, it should accurately measure the relevant size, and then according to the actual cutting, generally should not be cut according to the size of the figure, should be piece by piece number, detailed records in the special form. 3: laying impermeable membrane should try to weld at least, in ensuring the quality of the premise, as far as possible to save raw materials. But also easy to ensure quality. The lap width of the joint between the membrane and the membrane is generally not less than 10 cm, usually in the direction of the weld arrangement parallel to the maximum slope, that is, along the slope direction. 4: usually in the corner and the deformity of the lot should be shortened in length. In addition to the special requirements, in the slope of more than 1: 6 on the slope from the top of the slope or stress concentration area of 1.5 meters, as far as possible without weld.
I professional production, professional equipment construction, mainly with the pressure method to test the quality of weld
