# Site Preparation:

• Clearing and Grading
  It is necessary to remove any possible risks, including sharp items, plants, and debris, from the installation area. To guarantee homogeneity and reduce undulations that can put stress on the geomembrane, the surface should be graded.
• Subgrade Preparation
  The layer directly below the geomembrane, or subgrade, needs to be hard and smooth. After installation, the area needs to be compacted to avoid settling and any abnormalities need to be fixed.
• Geotextile Underlay (if required)
  Nonwoven geotextile layer may be positioned underneath the geomembrane to increase stability and offer further protection against punctures.

# Field Connection

a) Weather Conditions: Avoid installing under bad weather conditions to ensure the quality of the welds.

b) Welding Methods: Employ hot wedge welding, which eliminates the need to add additional materials to the welding process and doesn’t require roughening the film’s surface.

c) Seam Integrity: Ensure that the seams are free from dirt, sand, water, and other debris that could affect the quality of welding.

# Maintenance and Monitoring:

1. Regular Inspections
2. Repairs

HDPE geomembrane installation is a critical process that requires attention to detail and adherence to best practices to ensure the longevity and effectiveness of the containment system.
