# Key Steps in LLDPE Geomembrane Installation

1) Site Preparation

• Surface Grading
  Ensure that the surface where the geomembrane will be installed is smooth, free from debris, sharp objects, and large stones that could puncture the membrane.
• Subgrade Preparation
  The subgrade should be compacted and free of any protrusions. In some cases, a geotextile layer is placed beneath the geomembrane to provide additional protection.

2) Material Handling

• Unloading
  Care should be taken when unloading the geomembrane rolls to avoid damage. Use appropriate lifting equipment to prevent tears or punctures.
• Storage
  Store the rolls in a clean, dry area away from direct sunlight and extreme temperatures to prevent degradation before Installation.
