1. What Are Benifits of HDPE Fish Farm Pond Liner Material Philippines for Aquaculture Fish Pond
The Philippine aquaculture industry ranks eleventh in the world. The Philippines is an archipelagic country with rich aquatic life resources. Its sea area is about seven times the land area and its coastline is 36,289 kilometers long. Aquaculture has a long tradition. Coastal pond farming, which dates back to the 15th century, is diversifying. Saltwater pond fish farming dominates the country’s aquaculture, with the current development of freshwater pond fish farming, mollusk farming, cage and netting fish farming and algae farming.
The Philippine aquaculture industry has seen rapid growth in recent years, with aquaculture growing at the highest rate in the aquaculture industry. According to relevant data, at present in the fisheries industry under the three industries, aquaculture industry growth rate is the highest, followed by local fishing and commercial fishing. Production in the aquaculture sector comes mainly from pond farming (fresh and brackish water), cage and enclosure farming (fresh and sea water) and maricultural.
Customers from the Philippines needed to install fish ponds, mainly for carp breeding. After seeing the aquaculture cases on our website, they contacted BPM salespeople, communicated with us about their project area, specific number of fish ponds, recommended product thickness, and asked for samples, technical data, installation instructions, etc. We recommend the use of 0.75mm thick, ASTM standard, we arranged to mail the sample for the customer to test, received our sample a week later and sent it to the third party for testing, the result fully met the needs of the customer, and ordered our 60000 square meters of geomembrane a month later, to complete the installation of the first phase of the project.

3. What Is The Service Life Expectancy of Fish Farm Pond Liner Material
According to scientific research units, an impermeable polyethylene film with a thickness of 0.75mm, along with a stabilizer, can have a service life of 60 to 70 years under clear water conditions. In the case of sewage conditions, the working life is expected to be around 60 to 70 years. These estimates indicate that the service life of geomembrane is sufficient to meet the seepage control requirements of aquaculture engineering projects.
The service life expectancy of fish farm pond liner material, such as geomembrane, depends on its impermeability and waterproof properties. Geomembrane is a durable material that doesn’t degrade naturally, which means it remains intact for a long time. Although it can be challenging to dispose of or repurpose after use, it has minimal environmental impact.
Geomembrane provides a reliable and long-lasting solution for fish farm pond liners, ensuring effective seepage control and meeting the demands of aquaculture operations for an extended period.
4. Welding Methods of HDPE Fish Farm Pond Liner Material
The welding process for HDPE fish farm pond liner material involves several important steps:
- Adjusting Parameters: Begin by adjusting the pressure, temperature, and speed on the geomembrane welding machine. These settings are crucial for achieving proper weld quality.
- Surface Preparation: Ensure that the joints are clean and free from oil, dust, or any other contaminants. It is important that the lap surface of the HDPE geomembrane farm pond liner material is not filled with sand or debris. If any debris is present, it should be thoroughly cleaned before welding to prevent interference with the welding process.
- Daily Test: Start each day by welding a sample strip measuring 0.9mm × 0.3mm on-site. The lap width should be at least 10cm. Use a tensile machine to perform peeling and shear tests at the site to evaluate the strength and integrity of the weld. Once the sample passes the quality test, record the adjusted speed, pressure, and temperature. Mark the specimen with the date, time, and ambient temperature for future reference. Pay close attention to the operation of the welder throughout the welding process using a hot geomembrane welding machine. Fine-tune the speed and temperature based on on-site practices and observations to ensure optimal welding results.
- Welds shall be regular and beautiful, and no sliding welding or jumping phenomenon shall be allowed.
- When the length of geomembrane farm pond liner material is not good, the demand for long splicing should first weld the transverse seam, and then weld the longitudinal seam. The distance between the transverse weld is greater than 50cm should be a T-shaped, without cross insertion.
- The adjacent geomembrane farm pond liner material welding seam should be overlaps as far as possible. The junction formed between the film blocks should be T-shaped, and the cross type should be reduced as far as possible.
- Welding film is not allowed to press out the dead fold, laying HDPE geomembrane, according to the local temperature change range and HDPE geomembrane function requirements, set aside the elastic deformation caused by temperature change.
- When the temperature of the hand-held welder is lower than 200℃ as indicated by the temperature control of the hand-held welder, it is necessary to dust the welder with clean cloth or cotton yarn. If necessary, it should be repolished.
- When the joints are affected by condensation, wetting and sediment, welding shall be carried out after treatment.
- Welding cannot be carried out during the rain or in the case of moisture, dew, or sand at the seams, but the protective method is adopted outside.
- When the temperature is lower than 5℃, no construction shall be performed according to the standard requirements. If necessary, the welding machine shall be preheated before welding.
- Kneading welding machine in the welding process, should often check the gun head slider, wear more serious should be replaced in time to prevent damage to the film surface.
- Geomembrane liner in welding should be used to stabilize the function of the generator power supply, in special cases to choose local electricity, it is necessary to use voltage regulator.
