Pond liners play a crucial role in the success of aquaculture and aquaponics ventures, serving as the protective barrier that keeps water contained.
Manufacturers typically construct these liners from plastic derivatives such as HDPE, LLDPE, FPP, PVC, and EPDM. The process involves bonding synthetic fabric with a polymer.
Pond Liners for Aquaculture and Aquaponics: PVC vs. HDPE
Two of the most commonly employed pond liners are PVC (Polyvinyl Chloride) and HDPE (High-Density Polyethylene). On-site creation of low-water-permeable membranes involves applying polymer coatings like polyurea directly onto geotextile fabric along the pond’s surface.
A well-installed and adequately maintained pond liner can endure for approximately 15 to 20 years. However, this lifespan can drastically decrease if not professionally installed.
Aquaponics and aquaculture enthusiasts prefer PVC and EPDM pond liners, particularly when constructing holding tanks for fish or shrimp.
It’s important to emphasize that tarpaulin, often referred to as “tarp,” is not a suitable alternative to PVC pond liners. Tarpaulins, while they may repel water to some extent, are not fully waterproof and thus unsuitable for pond construction.
Utilizing PVC or EPDM pond liners for pond construction reduces costs, representing one of their primary advantages. PVC pond liners, in particular, offer a cost-effective solution. Additionally, pond liners allow for straightforward repairs through heat welding, ensuring long-lasting durability.
The choice of GSM (Grams per Square Meter) for the liner can vary depending on the type of cultivated aquatic life.
In general, GSM options 120, 160, 180, 200, 220, and 250 are used for pond construction. Various types and colours of pond liners are available, and both PVC and EPDM pond liners are non-toxic for aquatic and plant life.
UV-stabilized liners are suitable for outdoor use, while non-UV-stabilized liners work well for indoor setups shielded from direct sunlight in ponds.
Adding the appropriate level of UV stabilizers ensures that the liner remains durable even when exposed to sunlight. PVC pond liners, for instance, have a minimum lifespan of 10 years or more.
At KJA&Sons, we specialize in assisting you in selecting the right pond liner for your specific requirements. We can supply various types of liners and provide professional installation services.
The cost of pond liners is influenced by factors such as GSM and the quantity needed. Prices start at Rs 18 per square foot and increase as the GSM rating of the pond liner rises.
At KJA&Sons, we offer pond liners and various services like civil and commercial constructions, swimming pool installation, landscaping, and paving.
Our expertise also extends to quantity survey, land survey, building valuation, strengthening structures, waterproofing, electrical and plumbing work, and the creation of Thulsi Thara, sculptures, water features, and Koi Fishponds.
