Core Pain Points & Solutions
Water Leakage in Earthen Ponds:
Solution: Install HDPE liner for shrimp farming pond specification to ensure full impermeability.Poor Water Quality Control:
Solution: Use HDPE liner to isolate soil contamination and maintain stable water conditions.Frequent Maintenance Costs:
Solution: Reduce sediment accumulation and simplify cleaning with smooth HDPE surface.Liner Damage from Equipment:
Solution: Use appropriate thickness (≥0.75 mm) and protective underlayer.UV Degradation:
Solution: Ensure carbon black content and UV stabilization.
Risk Warnings & Mitigation
Thin liner selection → higher risk of puncture.
Improper installation → seam leakage.
Poor subgrade preparation → liner damage.
Excessive sun exposure before installation → reduced lifespan.
Procurement & Selection Guide
Define pond size, depth, and farming intensity.
Select HDPE liner thickness based on usage (0.5–1.5 mm).
Specify UV resistance and carbon black content.
Request technical datasheets and quality certifications.
Evaluate supplier production capability and delivery time.
Confirm welding method and installation requirements.
Consider long-term maintenance and replacement cost.
Engineering Case Study
A coastal shrimp farm project installed 0.75 mm HDPE liner across 50,000 sqm ponds. The liner reduced water seepage by over 95%, improved shrimp survival rates, and lowered maintenance costs. After 3 years of operation, the system maintained stable performance with minimal repair requirements.
