Why should pre-applied HDPE membrane have a margin during the construction process? Those who are familiar with pre-applied HDPE membrane products know that pre-applied HDPE membrane has a certain margin during the laying process, and pre-applied HDPE membrane should not be used.

Why should pre-applied HDPE membrane have a margin during the construction process? Those who are familiar with pre-applied HDPE membrane products know that pre-applied HDPE membrane has a certain margin during the laying process, and pre-applied HDPE membrane should not be used. The tension is too tight, what is the reason? The manufacturer of the impermeable membrane will take you to understand:

During the construction of the anti-seepage project, the foundation and side slope are tamped. In order to ensure the anti-seepage effect of the whole project, it is necessary to prevent the foundation and the side slope from sinking, especially if the foundation of the bottom of the project is not handled properly. Prone to sinking.
Once the ground foundation sinks, if the pre-applied HDPE membrane is laid too tightly, under the action of external force, the pre-applied HDPE membrane is easily stretched, which may cause safety hazards to seepage prevention quality.
If the external force is too large, the pre-applied HDPE membrane will be damaged or broken directly, and the entire anti-seepage project will be destroyed.
Therefore, in view of the above reasons, a certain margin should be left when laying pre-applied HDPE membrane.
Even if the ground foundation sinks, because the pre-applied HDPE membrane has a margin, in most cases, it will not cause safety hazards in the anti-seepage of the project.
