Site Preparation
Clear and level the ground, removing rocks, roots, and sharp objects.
Compact the soil to ensure a stable base and prevent punctures.
Geomembrane Installation
Unroll the geomembrane smoothly, avoiding wrinkles and folds.
Overlap adjacent sheets by at least 50 cm (20 inches) and weld them using thermal or solvent methods.
Ensure seams are properly sealed to prevent leaks.
Anchoring & Protection
Secure the edges with anchor trenches or fixing strips to prevent shifting.
Cover the geomembrane with a protective layer (e.g., sand or geotextile) to shield it from UV rays and physical damage.
Quality Control
Conduct leak detection tests (e.g., spark testing or vacuum box method).
Inspect seams and surfaces for defects before filling with water.
Final Steps
Gradually fill the pond to avoid stress on the geomembrane.
Monitor for settling or damage during initial use.
Key Considerations:
Use high-quality, UV-resistant geomembranes (e.g., HDPE, LLDPE).
Avoid walking on installed membranes with sharp footwear.
Follow manufacturer guidelines for welding temperature and seam strength.
This ensures durability and leak-proof performance in aquaculture systems.
