Non-Recycled HDPE Resin Resists Acids Alkalis 1mm 40Mil Aquaculture HDPE Geomembrane Liner Plastic Film Roll Fish Pond

Using an HDPE Geomembrane Liner for a Fish Pond is one of the most effective and reliable methods

for modern aquaculture. It creates a controlled, clean, and productive environment.

Key Steps for a Successful HDPE Liner Fish Pond :

1. Design and Planning
Pond Shape: Design slopes that are stable and easy to work on. A common slope ratio is

2:1 or 3:1 (horizontal:vertical). Avoid sharp corners; use rounded corners for easier liner installation and better water circulation.

Depth: Ensure a consistent depth suitable for your fish species, typically at least 1.5 meters (5 feet)

to provide stable temperature and space.

Inlet & Outlet Pipes: Plan the placement of water inlet and drainage pipes. The drain pipe should

be installed through the liner using a specially designed watertight boot flange to prevent leaks.

2. Site Preparation (The Most Critical Step)
A poor subgrade is the leading cause of liner failure.

Excavate and Compact: Remove all rocks, roots, and sharp objects.

Compact the soil firmly to prevent future settling that could stress the liner.

Smooth Surface: Create a smooth, uniform surface. Any small stone or root left behind can create

a pressure point and potentially puncture the liner over time.

Install an Underlayment: Always use a non-woven geotextile underlayment.

This protective cushioning layer is cheap insurance that absorbs pressure and protects the HDPE liner from punctures.

3. Liner Selection
Thickness: For most fish ponds, a thickness of 0.75 mm to 1.5 mm (30 to 60 mil) is sufficient.

Thicker liners (1.0mm+) offer more puncture resistance and are recommended for larger ponds or rocky subgrades.

Texture: Use a textured HDPE geomembrane.

Why? Textured surface provides critical friction, preventing the liner from sliding on pond slopes.

It also provides a safer, non-slip surface for personnel and is easier for beneficial biofilm to colonize without hindering cleanability.

Material Quality: Ensure the HDPE is made from virgin resin and is certified for potable water or aquaculture contact (e.g., NSF-61).

This guarantees no harmful chemicals will leach into the water and affect your fish.

4. Installation
Professional Welding: The panels of HDPE are joined together in the field using thermal fusion welding.

This should be done by certified welders to create a strong, watertight seam that is as strong as the liner itself.

Anchoring: The liner must be securely placed in a perimeter anchor trench. The liner is laid up the sides and

over the top, then buried in a compacted trench to hold it firmly in place.

Careful Handling: Installers should wear soft-soled shoes and avoid dragging tools across the liner to prevent damage.

5. Protection and Operation
Aeration: Place aeration diffusers on protective mats or pads to prevent abrasion on the liner floor from the constant vibration.

Water Level Management: Fill the pond slowly, checking for any adjustments needed as the water pressure settles the liner.

Cleaning: Between production cycles, the liner can be easily pressure-washed and disinfected with fish-safe disinfectants.

Aquaculture HDPE Geomembrane Liner  Installation and Maintenance :

Subgrade Preparation: The earth must be properly compacted, smooth, and free of all sharp

objects (roots, rocks). This is the most critical step for a successful installation.

Expert Seaming:

All field seams must be made by certified welders using thermal fusion (wedge or extrusion) and tested rigorously

(e.g., air pressure, vacuum box) to ensure a watertight seal.

Anchoring:

The liner must be securely anchored in a perimeter trench ("anchor trench") to hold it in place when the pond is filled.

Cleaning and Disinfection:

Between cycles, the liner can be pressure-washed and disinfected with approved chemicals

(e.g., chlorine, potassium permanganate) that are compatible with HDPE.
