How to use and pay attention to composite geomembrane

Composite geomembrane is an anti-seepage material commonly used in civil engineering and environmental engineering. It has excellent anti-seepage performance and anti-aging ability. This article will introduce the use methods and precautions of composite geomembrane to help you apply composite geomembrane correctly.

Choose the right composite geomembrane

Choose the appropriate composite geomembrane material according to project requirements. Common ones include HDPE, LDPE, LLDPE, etc. Select appropriate thickness and specifications based on project requirements.

Preparation

Before using the composite geomembrane, the construction site needs to be cleaned to ensure that the base surface is flat and free of sharp objects or sharp stones.

Check the geomembrane for damage or defects. If damaged, replace it in time.

Laying composite geomembrane

Before laying the composite geomembrane, a layer of sand can be laid on the land surface to provide a better base surface.

Unfold the composite geomembrane and lay it on the base surface, taking care to keep it flat.

The edges of the composite geomembrane should have sufficient overlap, and the overlap width is usually required to be no less than 30cm.

Use special geomembrane fixing clips or lay earth and stone to fix it to ensure that the geomembrane will not be blown or displaced by the wind.

Connect and patch

If you need to connect the composite geomembrane, you can use special connecting belts or hot melt joints for connection. Make sure the connection is tight and there are no leaks.

If the composite geomembrane is found to be damaged or perforated, it should be repaired in time. Use special repair materials to repair and ensure that the repair is tightly integrated with the surrounding geomembrane.

Construction Notes

During the construction process, avoid sharp objects or sharp tools from scratching the composite geomembrane.

To prevent the composite geomembrane from being exposed to the sun for a long time, you can use sunshade nets or other shields for protection.

Place warning signs around the construction site to alert others.

Acceptance and maintenance

After the completion of the laying of the composite geomembrane, acceptance should be carried out. Check whether the joints and repairs of the composite geomembrane are firm and troubleshoot potential problems.

Regularly check the condition of the composite geomembrane. If damage or aging is found, repair or replace it in time.

The correct use of composite geomembrane can effectively prevent soil leakage and soil erosion, and protect the environment and project safety. During use, be sure to follow construction specifications and precautions to ensure good performance and long-term use of the composite geomembrane.
