Installation Instructions

 

Geomembrane Installation Guide

 

Geomembrane, an essential geosynthetic material, is widely used in geotechnical and civil engineering projects. Its exceptional anti-seepage, corrosion resistance, deformation adaptability, and frost resistance make it indispensable in various construction applications. This detailed guide will walk you through the installation steps and precautions for geomembranes.

 

Installation Steps:

 

Preparation Work:

 

• Ensure the construction site meets the necessary requirements, removing debris and dust, and ensuring a flat and solid foundation.


• Avoid dragging or forcefully pulling the geomembranes during transportation and storage to prevent any damage.


 

 

Measurement and Cropping:

 

• Accurately measure the dimensions of the laying area before cutting the geomembrane to fit the actual needs.


• When cutting, leave a margin of 1.5% to account for local sinking and stretching, avoiding overly tight cuts.


 

 

Laying:

 

• Keep the geomembranes flat and tightly pressed from bottom to top, ensuring a secure fit between membranes and between membranes and the substrate.


• Allow for a slightly loose laying of the membrane to prevent the formation of bubbles at the bottom.


• Start laying from the slope and progress towards the bottom of the field. The film's direction should be parallel to the maximum slope line when laying the slope.


 

 

Joint Treatment:

 

• Ensure that the longitudinal joints of adjacent frames are not on the same horizontal line and stagger them by at least 1 meter.


• Place the longitudinal joint at least 1.5 meters away from the foot of the dam or the bend, on a flat surface.


• The overlap width between membranes should be no less than 10 centimeters.


 

 

Fixation and Protection:

 

• After laying the geotextile membrane, press it with sandbags to prevent wind movement.


• Record and number detailed information about corners and deformed areas on a dedicated form.


• Avoid sharp objects that may pierce the geomembrane during the laying process.


 

 

Welding:

 

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


• Ensure the two sides of the PE single film at the joint are flat, wrinkle-free, and overlap with a certain width before welding.


• Adjust the temperature and speed during welding to ensure a firm and secure weld.


 

 

Inspection and Backfilling:

 

• Perform a quality inspection after completing the laying and splicing of geomembranes.


• Backfilling operations should only be carried out after ensuring there are no damages, bubbles, welding leaks, or other issues.


 

 

Notes:

 

• Construction Environment: Ensure the cleanliness of the construction site and prevent dust and debris from contaminating the geomembrane.


• Material Protection: Avoid damaging the geomembrane during transportation and storage, and pay attention to precise dimensions when cutting.


• Joint Treatment: The joint is crucial for anti-seepage, so ensure firm welding and avoid any leakage.


• Climate Factors: Take protective measures on cloudy and rainy days to ensure the bonding surface is dry.


• Safety Protection: Strengthen labor protection measures for employees at the construction site.


 

 

In summary, the installation of geomembranes must strictly adhere to construction specifications, covering base treatment, cutting, laying, jointing, fixation, and backfilling. Each step directly impacts the project's quality and durability. Additionally, environmental and safety protection measures should be prioritized to ensure smooth construction progress.
