Installation Instructions

Geomembrane Installation Guide



 

Geomembrane Installation Guide

 

Geomembrane, a crucial geosynthetic material, is extensively utilized in geotechnical and civil engineering projects. Its exceptional anti-seepage, corrosion resistance, deformation adaptability, and frost resistance make it indispensable in various engineering applications. Below, we present a detailed overview of the installation steps and precautions for geomembranes.

 

Installation Steps of Geomembrane:

 

Preparation Work:

 

• Ensure the construction site meets requirements, remove debris, and ensure a flat, solid foundation.


• Avoid dragging or hard pulling geomembranes during transportation and storage to prevent damage.


 

 

Measurement and Cropping:

 

• Accurately measure the laying area dimensions before cutting the geomembrane.


• Leave a margin of 1.5% for local sinking and stretching when cutting.


 

 

Laying:

 

• Keep geomembranes flat and tightly pressed from bottom to top during laying.


• Ensure a slightly loose laying to prevent bubbles at the bottom of the membrane.


 

 

Joint Treatment:

 

• Stagger longitudinal joints by more than 1 meter and place them at least 1.5 meters away from the foot of the dam or bend.


• Overlap width between membranes should be at least 10 centimeters.


 

 

Fixation and Protection:

 

• Press geotextile membrane with sandbags after laying to prevent movement.


• Avoid sharp objects piercing the geomembrane during laying.


 

 

Welding:

 

• Use hot melt welding or special adhesive bonding for welding.


• Ensure flat, wrinkle-free sides at the joint with a certain overlap width before welding.


 

 

Inspection and Backfilling:

 

• Conduct quality inspection after laying and splicing geomembranes.


• Backfill only after ensuring no damages, bubbles, welding leaks, or other issues.


 

 

Notes:

 

• Construction Environment: Maintain cleanliness to prevent contamination.


• Material Protection: Avoid damaging geomembrane during transportation and storage.


• Joint Treatment: Ensure firm welding to prevent leakage.


• Climate Factors: Take protective measures on cloudy or rainy days.


• Safety Protection: Implement labor protection measures at the construction site.


 

 

Strictly adhere to construction specifications for geomembrane installation, from base treatment to backfilling, to ensure project quality and durability. Pay attention to environmental and safety protection for smooth construction progress.
