Building a Geomembrane Biofloc Pond with HDPE

Biofloc is a farming technique for catfish, fish, shrimp and other farmers that uses probiotic bacteria to process the organic waste produced from digestion and leftover feed. A geomembrane biofloc pond helps make this technique very effective at increasing productivity and maintaining water conditions.

Biofloc ponds usually use a circular steel frame lined with tarpaulin. Tarpaulin is considered economical and easy to shape. However, it is not durable, so farmers must check it regularly to make sure it is still in good condition.

HDPE geomembrane sizes and specifications

Using tarpaulin to build biofloc ponds is a hassle for farmers. We offer a solution for anyone starting a biofloc farming business: geomembrane.

Here are the advantages of geomembrane and why we recommend it for lining biofloc ponds.

Heat resistant

Geomembrane withstands temperatures of up to 90° Celsius, so it can be used on surfaces exposed to direct sunlight.

Waterproof and corrosion resistant

This makes it suitable for biofloc lining, because it can stay submerged in water for long periods without risk of damage.

Does not leak easily

Geomembrane does not scratch easily, let alone leak. This gives farmers peace of mind that their pond will not leak, so they do not need to keep monitoring it for leaks.

Available in various thicknesses

Geomembrane comes in a range of thicknesses, from 0.5 mm to 2 mm. The thicker the geomembrane, the more durable it is.

 Flexible (easy to shape)

It is easy to shape to the biofloc pond frame. Geomembrane also follows the pond’s curves better, so the folds are stronger and do not come loose easily.

Lasts Up to 10 Years

The HDPE (High Density Polyethylene) in geomembrane allows it to last up to 10 years. Farmers do not need to replace the geomembrane when starting a new farming cycle, and this can be repeated for up to 10 years. As a result, profits are also higher.
