The Laying Of HDPE Membrane

Jiangsu Hanovo New Material Co.,Ltd | Updated: Jul 13, 2017

1. The construction of HDPE membrane should be the corresponding acceptance of civil engineering certification documents. 2. HDPE membrane before cutting, should accurately measure its relative size, HDPE geomembrane and then according to the actual cutting, generally not in accordance with the size of the diagram, should be numbered by piece, detailed record in the special form.

3. When laying HDPE membrane should strive for the least weld seam, in the premise of guaranteeing quality, as far as possible to save raw materials. 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 arrangement direction parallel to the maximum gradient, which is arranged along the slope direction.

5. Usually in the corner and the deformed lot, the seam length should be minimized. In addition to the special requirements, in the slope of more than 1:6 from the top slope or stress concentration area within 1.5 meters, as far as possible without the weld.

6. HDPE membrane in laying, should avoid artificial folds, when the temperature is low, should be tightened as far as possible, pave.

7. After the completion of HDPE membrane, should be minimized in the film surface walking, moving tools and so on, where the impervious film can cause harm to the object, should not be placed on the membrane or carried on the membrane to walk, lest the film caused accidental damage.
