Polyethylene geomembrane is also known as high density polyethylene film and HDPE geomembrane, or "HDPE impervious membrane". HDPE impervious membrane is a plastic coil made of HDPE resin, and its HDPE is a high degree of crystallinity and non-polar thermoplastic resin. The surface of the original HDPE is milky white with a translucent appearance in the thin section. Of course, the quality of HDPE impervious membrane prices will certainly be higher. However, only to ensure that the quality of the HDPE impervious membrane is not enough, if there is a mistake in the construction link, it will be serious after the use of the effect and so on. Therefore, the expensive polyethylene geomembrane can not be destroyed in the construction!

HDPE impervious membrane construction technology (Professional Edition); 1, should be extended from the bottom to the high, do not pull too tight, should stay 1.50% remaining, in order to prepare local subsidence stretching. Considering the actual situation of the project, the slope should be laid from top to bottom; 2, two adjacent longitudinal joints should not be in a horizontal line and should be over 1m above each other; 3, the longitudinal joint should be above the 1.50M of the foot and elbow, and should be located on the plane; 4, the bottom of the slope before the slope; 5, Bian Popu At the time of setting, the direction of spreading should be basically parallel to the maximum slope line. Preparatory work before laying: 1. Foundation treatment: cleaning the geomembrane laying surface, requiring basic leveling, solid soil, not uneven, cracks, etc. There should be no sharp objects, stones, iron wire, wooden sticks, etc. the lawn and root of the impervious area should be removed, and weeds should be sprayed with herbicide. 2, with the membrane interface, laying a small sand or clay layer as a protective layer, the thickness of the protective layer should not be less than 30cm.


Paving process: 1. before the laying of HDPE impervious membrane, the corresponding acceptance documents for civil engineering should be obtained. Before the 2. geomembrane is cut, it should measure its related dimensions accurately, and then according to actual cutting, it should not be cut according to the graphic size. It should be numbered by piece and recorded on the special form in detail. 3. when laying geomembrane, we should strive to minimize welding seam and save raw materials as much as possible while ensuring quality. At the same time, it is also easy to ensure quality. 4. the lap width between the membrane and the membrane is generally not less than 10cm, which usually makes the weld alignment parallel to the maximum slope, that is, along the slope direction. 5. usually in corners and deformed areas, the length of joints should be reduced as short as possible. Except for special requirements, there is no welding seam as far as the slope with a slope larger than 1:6 is within 1.5 meters from the top slope or the stress concentration area. 6. in the laying of geomembrane, artificial folds should be avoided. When the temperature is low, it should be stretched and smoothed as far as possible. 7. after the completion of the geomembrane, we should minimize the walking and moving tools on the surface of the membrane. All the objects that can harm the impervious film should not be placed on the membrane or carried on the membrane, so as to avoid accidental damage to the membrane.


The senior manufacturer of HDPE impervious membrane, Shandong Dageng Projecct Material Co., Ltd has a senior product technical engineer, construction engineer and a number of professional construction teams. The business is distributed all over the country, accumulating rich experience in construction and service, and undertaking the welding construction of geomembrane.
