What need to do after Installation of HDPE Geomembrane
Procedures After the Construction of HDPE Geomembrane
After the construction of the HDPE anti-seepage geomembrane is completed, some projects also need to carry out pipeline installation, anti-corrosion and other projects, and there is the possibility of damage to the anti-seepage membrane due to poor protection of the finished product.
Based on the data of the HDPE impermeable membrane, before the completion of the project, the surface of the impermeable membrane and the entire impermeable system of the welding seam must be tested and accepted. Improve the original design full water test, using the double electrode method and arc method detection method.
Determine the location of the leakage point according to the spark position of the arc brush, cut the anti-seepage film at the position where the spark is emitted, and check the damage. Identify the hole, take a picture and record the hole location. If no holes are found after excavation, continue to narrow the detection distance and carefully measure to determine whether it is a misjudgment.
