Fish pond liners are made of several materials that vary in price. The most expensive of them all would be the High Density Plastic or HDPE! This plastic is very thick and has excellent structural integrity and chemical resistance. It is however quite heavy and thus needs to be properly supported at all times.
The next type would be the Low Temperature Resistance or HPR. These liners are available in different varieties with a range of grades from Low to Premium and have a very low cost per ton. The material used in this pond liner is polyethylene terephthalate or PET. The material’s chemical makeup is similar to that of Vinyl but with a much lower density.
The pond liner price for a High Density Plastic liner would be around $90, whereas a High Temperature Resistant liner would be around $150. An example of this would be Geofilm or Liquid Heater Liners. A Low Temperature Resistant liner is also available in the form of Lowthermal, thermoplastic polyethylene or TPR.
It is common to find the term “low slope protection” in the specifications of these pond liners. This is another way of stating an anti-seepage device such as an anti-static agent. The seepage can easily occur when the bottom of the pond is not properly drained or cleared.
Other things that affect the liner price include the physical size, the color, the pattern, the style, the texture and the finish. Each of these features plays a major role in determining the final price. For instance the physical size refers to the overall size of the garden pond design. The color and pattern are determined by factors such as whether it is going to be used as a free standing structure or a part of a larger landscape. The style is chosen to match the look and feel of the garden design.
Some examples of the material used are polyethylene, polyester, rigid plastic or rubber. A major concern in recent years has been the use of PVC plastic. The material contains bisphenol A (BPA), a known carcinogen. So, the best material to use is a water conservancy product with a low concentration of BPA. Another major consideration is the thickness of the liner. Fish ponds may be wider than they are tall and therefore, the thickness needs to be considered.
When shopping for a quality control report, it should include not only the physical dimensions but also any chemical balance testing. This testing should be done before the liner goes into production. When shopping for the raw materials, it is advisable to buy from a reputable supplier that has experience in production. Geosynthetics suppliers should be able to provide references of other customers. It is also necessary to check the manufacturer’s website for product quality control information. Many suppliers offer guarantee programs and customer service.
Some important characteristics to look for are a high degree of watertight integrity, excellent anti-seepage resistance, and low temperature resistance. The thickness of the liner is also an essential factor in determining the cost of the product. Fish pond liners can range from four inches to thirty-six inches. Some of the more popular products are those that are available in a low pressure setting up to fifteen gallons per minute at a depth of between one to four feet.
Other specifications to consider are the type of support systems required, such as float alone or float and screen or cable support. A minimum tensile strength (weight rating) of one hundred and twenty pounds is recommended for marine applications. There is no difference in cost between a single layer and two layers of multi-layered membrane. The most common type of geomembrane is made from rubber and/or plastic fabrics. The most expensive varieties are constructed of diamond and titanium.
Some important questions to ask the dealer are as follows: How old is the geomembrane? What grade and thickness of raw materials is used? Is the geomembrane compatible with my existing drainage and circulation system?
Obor Geomembrane is very strong and highly resistant to chemicals. It can be installed either on concrete slabs in a skimmer or on the surface of an artificial pond. The book is available in different thicknesses suitable for different pond applications. It is a low maintenance, waterproof membrane. Its price ranges from one hundred to eight hundred dollars per square foot.
