Making a budget for pond construction is not choosing the cheapest materials, we need to go from at least three aspects in the following.
1. Firstly, check the pond land situation before determining which thickness or materials will be suitable for the land. If there’s quite hot and wet weather, the soil is not so hard. We could pick up the liners with thicknesses between 0.5 mm to 1.5 mm of the pond liner. But, if there’s always cold and dry weather, you need to consider the soil with hard rocks. The situation will be bad for the service life of the pond liner.
Considering this, we could cover the bed with soft soil or sand to protect the liners before laying the first layer of the liner materials. Also, we could use other kinds of materials like geotextile to replace the sand. The geotextile is not only protecting the liners but also helps the soil reinforcement in case the water flows causing soil erosion.
2. Secondly, confirm the pond size by calculating the pond width, length, depth, etc. The importance of getting an accurate estimation of your pond surface area cannot be overestimated. The majority of pond owners estimate their pond area, which usually results in an overestimate of the true pond surface area. Pond area and water volume should be calculated based on some simple measurements. The effort necessary to estimate pond surface area is related to your pond’s shape and uniformity. The simplest method–using basic equations for common shapes–can be applied if your pond resembles a circle, square, rectangle, or trapezoid in shape.
3. Choosing the right pond liner material and kindly arrange the best installation team. The suitable liners will make your pond a perfect construction and long-term project, which will also save the repairing cost a long time.

So about the cost of pond liner, we supply the LLDPE material for aquaculture farming and reservoir irrigation, etc. LLDPE liners cost about 0.7 to 0.9 USD per square meter upon different thicknesses. Omit pricing, RPE and PVC can be close to the same cost for a large pond liner. High-density polyethylene (HDPE) is sometimes suggested because it’s a cheaper material by the square foot, but it has significant drawbacks in the actual field installation, which is where the true cost of a liner becomes clear. In the installation part.
Dajin Geosynthetics has exported liners all over the world. In African countries, our clients are willing to choose lower thickness when doing aquaculture farming and agriculture irrigation. Like 0.5, 0.7, or 0.75 mm, it can be used for over 20-30 years with UV resistance and high and low-temperature resistance. Actually, the thickness is on the project requests not only the pricing. If you are doing the landfill project, since this will be related to environmental protection, we need it to be a long service project for us. Usually, we recommend the HDPE geomembrane for landfill, since it is superior performance in the high tensile strength, UV resistance, and corrosion resistance. In landfill construction, there are many harmful items that will destroy the liners during usage. It is important if the liners can play the role of anti-seepage function.


Lots of our clients have tried the original ways like the concrete or the soil to hold water for their farm pond or other liquid. it will work, generally, it can’t last for a long time to serve the whole system. Then it will cost more time and money to repair and rebuild the system. So it’s not a long-term solution when we are considering the pond for over 20 to 30 years of application. Dajin Geosynthetics has been a professional manufacturer of geomembranes and geotextiles with over 20 years of experience. The pond liners come with big rolls like 3*100M, 6*100M, 7*140M, 8*100M, etc. It covers an area from 300 square meters to 1500 square meters. The liners are wrapped well for shipping via trucks or any other means of transport. The package can do custom with black or white woven bags according to your project requests. You must have a forklift or front-end loader with forks on your end to take the skid off the truck. With the easy installation, pond liners are becoming more and more popular for aquaculture farming. After digging the pit and finishing the preparation work of the soil pond, then you need to prepare the first layer of the pond, also you need to finish the pipe system before installing the pond liners. You need to open the rolls and then lay the liners on the ground.



It’s easy to lose sight of the big picture when you are specifying a geomembrane. There are many factors one must consider to choose the best fit for your application, but, lifetime cost is often overlooked. A geomembrane with a low initial cost might cost you as much, if not more than, a geomembrane that costs more upfront. Before signing the check, you should uncover the real geomembrane cost by looking at the usual costs incurred over the lifespan of the product.
So how to tell the different quality of the pond liner when planning to do the sale? The surface of the pond liner made of 100% virgin resin is smooth and bright, with no smell. It is especially important to choose the virgin materials’ liners when you are doing farming or irrigation industry. There are different classes of quality liners in the market, some low-cost liners may save you money in a short period, but they will be broken within a short time. The liners made with recycled resins are a rough surface with a heavy smell which is harmful to biology and the environment, it will also release harmful items during the use period. Some professional test reports or certificates of the pond liners are also a must when checking the quality. Apart from the surface and the certificates, the technical data of the different quality liners is apparently a large difference. No matter the tensile strength or cracking strength, if the land situation is not so good, after years’ usage, the geomembrane will be teared up easily, then you need to do the second time installation. A quality geomembrane liner will not only prevent water loss but also prevent the chemicals from leeching into the water table.
It is important to note that the pond liner material costs above include both shipping and fabrication. The costs are approximated and can vary based on the project size, but. For example, larger jobs will have lower material and fabrication costs per square foot. HDPE prices tend to fluctuate as well, so be sure to reach out to the appropriate manufacturer when creating your own price comparison. The cost is going to be much lower for flexible/fabricated geomembranes because there are far fewer field seams.
Your geomembrane must maintain in order for it to continue performing at its best. The amount of maintenance necessary varies from one geomembrane to another. Some geomembranes, like HDPE, are plagued by environmental stress cracking, while others are engineered with low thermal expansion properties making these geomembranes more dimensionally stable. Environmental stress cracking can occur anytime during the lifespan of your geomembrane, meaning you might have to replace the geomembrane before seeing a return on your investment.
Ultimately, you should not decide on a geomembrane based on the initial cost. The extra expense will sneak up on you, resulting in a greater lifetime cost. Make sure to do your research and weigh your options to find a product that fits both your performance and budgetary requirements.
