Here’s a simple breakdown of the geomembrane installation process followed by our certified installation teams:
Step 1: Site Preparation
Before any geomembrane is laid, the surface must be clean, smooth, and free from sharp objects like stones or debris. This prevents punctures and ensures even contact between the liner and subgrade.
Step 2: Material Inspection & Layout
Each roll of geomembrane sheet is inspected for uniform thickness, flexibility, and strength. Rolls are then laid out according to the project’s design plan to minimize waste and seams.
Always use sheets from a verified manufacturer like Decora to ensure material consistency.
Step 3: Welding & Seaming
The sheets are joined using hot wedge or extrusion welding machines to create seamless, leak-proof joints. This process is crucial for ensuring long-term impermeability and resistance against environmental stress.
Step 4: Anchoring & Edge Treatment
The geomembrane edges are securely anchored in trenches or fixed using anchor beams to prevent slippage or uplift caused by wind or fluid pressure.
Proper anchoring is key to preventing liner movement, especially in ponds or reservoirs.
Step 5: Quality Control & Testing
After installation, the entire liner system undergoes rigorous quality checks—including visual inspection, seam testing, and sometimes electrical leak detection—to ensure perfect installation.
Always demand a post-installation inspection report for quality assurance.
Step 6: Covering or Ballasting (If Required)
In some projects, geomembranes are covered with soil, gravel, or concrete to protect them from UV exposure and physical damage. This step enhances lifespan and performance.
Use protective layers especially in high-traffic or exposed environments.
