Geomembrana HDPE liner, also known as HDPE geomembrane liner, is the ideal geosynthetic material for anti seepage lining projects such as aquaculture farm, water containment, waste containment and landfill applications. BPM Geosynthetics had provided more than 300,000 square meters geomembrana HDPE liner, 20 sets welding machine and 20,000 m geolock for aquaculture farm project since 2018 in Sri Lanka. Sri Lanka is an island country in the Indian Ocean, at the southern tip of the South Asian subcontinent, close to the equator. Sri Lanka almost stays in summer all year round, and it has only the rainy season and the dry season, without four seasons. It belongs to a tropical monsoon climate with an average annual temperature of 28℃.S ri Lanka’s arable land area is about 4 million hectares and accounting for 61% of the country’s land area, of which nearly 2 million hectares have been used .Sri Lanka’s fisheries are roughly composed of four parts, like coastal and offshore fisheries, offshore and deep-sea fisheries, inland fisheries and aquaculture in coastal areas. The main products are Japanese mackerel, black body, bonito and yellowfin tuna, etc. The main export products are farmed shrimp, lobster, crab, finned fish and ornamental fish.
Sri Lanka’s fish and aquatic products are best sale in the global market. At present, Sri Lanka’s export volume is still unable to meet the global market demand. Therefore, the government has taken corresponding measures to start the fisheries development plan including development of grouper like finfish, catfish and other finfish, implementation of aquatic resources development plan, development of marine fish, ornamental fish, seawater, paddy fish farming, Vannamei shrimp Industry.
Characteristics of Geomembrana HDPE Liner
The aquaculture farm industry runs in a collective mode. BPM Geomembrana HDPE liner is the ideal anti-seepage material in aquaculture farm project. It is conceivable that there are definitely many residues in the water body and the water quality is necessarily bad. In order to prevent this phenomenon, geomembrane HDPE liner is laid around the pond to block some dirt. The anti-seepage performance and excellent long-term performance for geomembrana HDPE liner can protect groundwater resources from pollution. Therefore, in the field of aquaculture farm, the application of geomembrana HDPE liner is also more extensive. The application of geomembrane HDPE liner in the aquaculture industry can have a good protection effect.

Case Study of Geomembrana HDPE Liner for Aquaculture
BPM client is the leading seafood and the largest vannamei company in Sri Lanka, the client’s vision is to produce seafood with impeccable freshness and quality. BPM client inquired HDPE geoemembane liner and sent us the design drawing for aquaculture farm project. BPM suggested using 100% virgin material geomembrane HDPE liner with thickness of 0.5mm or 0.75mm. Through communication and negotiation, BPM client chose 0.6mm GM 13 standard geomembrana HDPE liner finally. In the meanwhile，BPM showed the its company profile, application cases and professional certificate of HDPE geomembrane liner to clients. BPM shared its geomembrane factory, team and HDPE liner pictures. After our client knew us, BPM sent geomembrana HDPE liner samples to client to test as clients’ request. BPM HDPE geoemembrane liner passed the test, and the client placed the trial order.
BPM Sri Lanka client requested three professional BPM welding workers to install on site for the first batch HDPE liners and taught local worker how to weld geomembrane liner. To save clients’ cost, we told clients the basement surfaces should be at the same level and free of all sharp rocks (all rock and stone greater than .05 diameter), objects, vegetation and stubble. (Soil sterilization may be necessary to kill roots and certain types of grasses.) The subgrade surface should provide a unyielding foundation for the geomembrane line with no sharp or abrupt changes or break in grade. Proper compaction assures stability and support of the liner. If BPM welders came there, even if they did not work, they would be charged per day. So BPM let customers send pictures on site to ensure time and cost savings.
BPM geomembrana HDPE Liner is fabricated into large standard rolls to minimize field seaming. BPM recommended that protective covering of HDPE geomembrana liner not be removed until installation and any uncovered should be stored out of direct sunlight. BPM also offer double-layer woven bags to cover and protect delivered liner rolls.
