We line fish ponds and shrimp ponds for aquaculture farms, including grow-out, nursery, hatchery and settlement ponds, and we also supply HDPE rolls on their own.
Typical projects
- Fish and shrimp grow-out and nursery ponds
- Hatchery and settlement ponds
- Farm water storage
Fish ponds
A fish pond liner has to hold water without seepage, stay smooth enough to clean and disinfect between cycles, and suit the stock. HDPE to GRI-GM13 is made from virgin resin with no post-consumer recycled material, and its seams are heat-welded rather than taped or glued.
Shrimp ponds
Shrimp ponds are often filled with seawater or brackish water. Salt is not a problem for HDPE: manufacturers' chemical-resistance tables rate it as little or not affected by salt water. What matters is UV resistance on exposed slopes, protection where harvesting and pond-cleaning equipment works, and a liner that can be dried out and cleaned between crops.
Choosing the liner
Aquaculture ponds commonly use 0.75–1.5 mm HDPE, chosen for the pond size, the subgrade, and whether the liner is exposed or covered. For stock, specify a liner made from virgin resin that is suitable for contact with water and fish.
Farm ponds
We line farm irrigation ponds and water storage as well as industrial ponds, with the same panel deployment, hot wedge welding, repairs and field QA testing on every job.
Tarpaulin (شراع or طربال) or HDPE liner?
Many farmers ask for a شراع or طربال (tarpaulin) for their pond. A tarpaulin is a cover sheet, made from coated fabric or from woven polyethylene strips laminated with plastic sheet, to protect goods and loads from wind, rain and sun. It is not made or tested to a geomembrane standard. For a permanent fish or water pond, the purpose-made liner is an HDPE geomembrane: at least 0.75 mm thick to GRI-GM13, with 2–3% carbon black for UV resistance, and heat-welded seams that are tested on site. That is what we supply and install.
Frequently asked questions
Is an HDPE liner suitable for fish and shrimp?
Use HDPE made from virgin resin that the manufacturer states is suitable for contact with water and fish. GRI-GM13 requires virgin resin (with no more than 10% rework of the same HDPE) and no post-consumer recycled material, so ask for GRI-GM13 material with the manufacturer's certificate.
Can I use a tarpaulin (شراع or طربال) instead of an HDPE liner for a fish pond?
A tarpaulin is waterproof, but it is made as a cover, not as a pond liner, and is not made or tested to a geomembrane standard such as GRI-GM13. For a permanent fish or shrimp pond, use an HDPE geomembrane with heat-welded seams that are tested on site.
Do shrimp ponds filled with seawater need a special liner?
Not for the salt: manufacturers' chemical-resistance tables rate HDPE as little or not affected by salt water. Choose the thickness for the pond size and the ground, use GRI-GM13 material for UV resistance on exposed slopes, and protect the liner where harvesting and cleaning equipment works.
