Our company, Shanghai Yingfan Environmental Engineering Co., Ltd., is one of the biggest HDPE pond liner manufacturers in China. In recent years, our production capacity of HDPE pond liner is ranging top 1 in our country thanks to that we have three pond liner production lines in our factory.
Pond Liner Introduction (cited from wiki)
A hdpe pond liner is an impermeable geomembrane used for retention of liquids, including the lining of reservoirs, retention basins, hazardous and nonhazardous surface impoundments, garden ponds and artificial streams in parks and gardens, but not limited to these applications.
HDPE pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, geotextiles (particularly needle-punched nonwovens) and other materials. Pond liners are manufactured in rolls or accordion-folded on pallets. When deployed in the field , their edges and ends are overlapped and seamed together. Methods are thermal fusion, solvents, adhesives and tapes.
Pond Liner: HDPE Pond Liner
We are a famous manufacturer of HDPE pond liner (LLDPE pond liner is also produced but HDPE liner is used more widely than LLDPE one), located in Shanghai China. The low permeability of our pond liner (≤1.0×10-13 g•cm(cm2)•pa) contributes its good retention property of any liquid such as water, waste or hazardous liquid. Because of its good chemical resistance, it is suitable for any acid or alkali liquid within ph 2-14. As HDPE pond liner has excellent UV and aging resistance property, yet it can have long life span in these applications.
Specification
Our HDPE pond liner product is manufactured in accordance with GRI-GM13 and ASTM standards, ISO standard and our domestic relevant standards. We can provide our product to any third party to be tested and make sure it meet our clients’ requirements.
Our thickness range for pond liner is from 0.15mm to 2.0mm. Maximum width is 8m and some extra thin polyethylene pond liner can reach 9m. Length can be 50m, 100m, 150m or others. Popular color is black and green. Other colors are also available. Pond liners are packed by rolls.
Installation Service Supply
We are one of the leading geomembrane pond liner installation contractors with more than 15 years in this industry across our country. We provide not only the best (fish) pond liners but also the best installation service for you. Our installed projects involved in many fields such as aquaculture farming pond, artificial lakes or lagoons, hazardous ponds, reservoir, and so on. Especially in aquaculture farming pond system, our HDPE pond liner product and installation service have dominated this market in south of China including Guangdong, Fujian, Hainan and Guangxi. Our products also play an important role in the aquaculture pond lining markets in abroad such as Indonesia, Philippines, and so forth as well as our installing supply.
Special Focus: Aquaculture Farming Pond Liner system
Below are scientific references to support the use of HDPE geomembrane in aquaculture farming application:
(1) Aquaculture farms in Belize: Robins P. Mclntosh, 2000, reported how using an HDPE liner reduced erosion of pond banks, increased the speed of the turn-around time between crops, sustained water levels, and improved pond efficiency.
(2) Agromarina de Panama Farm, Panama: Bray et al., 2001, issued a report describing how the destructive White Spot Syndrome Virus(WSSV) was bringing production to a halt in earthen ponds. The report found that survival rates increased from 9% in earthen ponds to 80% in ponds lined with a 0.75mm HDPE geomembrane.
(3) East Java, Indonesia: N. Taw et al., 2002, reported that productivity improved from 3634kgs/ha in an earthen pond to 10094kgs/ha in ponds lined with HDPE geomembrane.
Our aquaculture/shrimp/fish/turtle/koi fish/commercial large fish pond liner thickness include .35mm, .5mm, .75mm and other thickness. Any size of pond, 50 x50 pond, 75 x75 pond, 100 x100 pond, 1 or 2 or 3 or any ace pond size, can be suitable to use our HDPE hard/rigid/solid and flexible liners. 45mil, 60mil (1mm), 80mil thick HDPE pond liners are also used in other kinds of ponds.
