# Site Preparation
  • Clearing and Grading
    It is necessary to remove any possible risks, including sharp items, plants, and debris, from the installation area.
  • Subgrade Preparation
    The layer directly below the geomembrane, or subgrade, needs to be hard and smooth.The surface needs to be graded to ensure uniformity and lessen undulations that could strain the geomembrane.
  • Geotextile Underlay (if required)
    Underneath the geomembrane, a nonwoven geotextile layer can be added for stability and further puncture protection.

#Welding Equipment

  • Hot Wedge Welders
    Best for long, straight seams.
  • Extrusion Welders
    Ideal for detailed work, repairs, and seams that require a thicker bond.
  • Hot Air Welders
    Useful for small, precise welds and detailed repairs.

#Applications

  • Landfills: HDPE liners are used to prevent leachate from contaminating groundwater.
  • Ponds: Ensures a waterproof barrier in artificial ponds.
  • Tunnels and Canals: Provides a waterproof layer in construction projects.
