What Does a Geomembrane Liner Cost?

What are geomembrane liners?

What is geomembrane liner made of? What advantages does geomembrane liner have? For what application do we use geomembrane liner?  And if you deploy a geomembrane liner in a construction project, How about the cost? This article will provide you with clear knowledge of the above questions.

Geomembrane liner

Generally, geomembrane liner is the flexible plastic waterproof construction material with very low permeability synthetic membrane liner or barrier so about control fluid, liquid, or gas migration in a human-made project, structure, or system from the bottom base. According to the material classification, there are four main types, high-density polyethylene (HDPE) which is the most used type, low-density polyethylene(LDPE), linear low-density polyethylene (LLDPE),  polyvinyl chloride (PVC), ethylene propylene diene terpolymer (EPDM).  Geomembrane liners are made from thin continuous polymeric sheets, but they can also be made from the impregnation of geotextiles with asphalt, elastomer, or polymer sprays, or as multilayered bitumen geocomposites. Continuous polymer sheet geomembranes are, by far, the most common.

Among all types, HDPE geomembrane liner is the prior product for lining projects especially when the liner strength is required. HDPE liner is resistant to many different solvents and is the most used geomembrane liner in the world. Although HDPE geomembrane liner is less flexible than LLDPE, it provides higher specific strength and can withstand higher temperatures, ultraviolet resistance properties make it a cost-effective product.

Shandong Dajin uses geomembrane liners to cut the effect of human development on the environment. They are especially important for waste containment. Our products are manufactured from durable materials, often with an expected lifetime of hundreds of years. They are resistant to chemicals and wear so that the passage of time and corrosion does not affect the integrity of the geomembrane liner. Each type of geomembrane liner material has specific characteristics which affect installation procedures, lifespan, and performance. Shandong Dajin offers a variety of materials based on the specific needs of your project.

Advantages of geomembrane liner

1. High-quality flexible waterproof material with very high impermeability

2. With its dense configuration, the geomembrane liner is resistant to oil, strong acid, and strong alkali.

3. Good heat and cold resistance performance. The geomembrane liner can withstand temperatures from -70℃ to 110 ℃.

4. Strong weather resistance and aging resistance. The service life can be up to 50 years even if it’s exposed to the outdoor environment. Because it is UV stable, No need to cover the liner under sunshine so it’s cost-effective.

5. Higher specific tensile strength and elongation at break. It can be used in severe geological and climatic conditions as well as adapt to geological differential settlement.

6. The geomembrane liner is easy to deploy in construction means the ability to save labor cost and time.

Where do you need to use the geomembrane liner?

1. Irrigation ponds, canals, ditches & water reservoirs, dams

2. Mining heap leach & slag tailing ponds

3. Golf course & decorative ponds

4. Landfill cells, covers, & caps

5. Wastewater lagoons, sewage treatment plant

6. Seepage prevention of landscaping

7. Chemistry factory, refinery, oil storage tank.

8. Power station

9. Aquaculture business

10. Secondary containment cells/systems

11. Liquid containment, environmental containment, soil Remediation.

What does a geomembrane liner cost?

When you start a new project, there is a wide range of options when it comes to the initial investment and long-term maintenance costs. No project is too small, or too big, and the growing market of available products and new technology will only make this truer. That means before you start it, taking every factor into consideration to choose the best fit for your application is a prior decision to make a good initial step and also leads you to a smooth construction process. It’s very important to see the sight of the big picture when you are specifying a geomembrane. A geomembrane with a low initial cost might cost you as much, if not more than, a geomembrane liner that costs more upfront. Before signing the check, you should uncover the real geomembrane liner cost by looking at the usual costs incurred over the lifespan of the product.

Initial costs can be divided into three main areas: material costs, installation fees, and the cost of construction maintenance. Although material costs have a serious impact on the lifetime cost of your geomembrane liner, for less expensive materials, a good part, if not the majority, of capital will be spent on labor.

It is important to note that the material costs mentioned above include both shipping and fabrication. The unit price for geomembrane liners can vary based on the project size. For example, larger projects will gain lower material and fabrication costs per square meter. HDPE prices tend to fluctuate as well, so be sure to reach out to the appropriate manufacturer when creating your own price comparison. Choosing a good supplier with stable proper quality and competitive price is the very key step to start.  

For the material cost, one option should be noted. It’s the cost impact of adding a geotextile to a geomembrane liner. Even though the geomembrane liner is already pretty high tensile strength, in terms of high construction requirements,  for some projects, you need more geotextile to increase puncture strength to the high level, resulting in extra geomembrane liner costs to the installation price.

Installation can be the weakest link in the chain of steps required to create a durable pond liner as the installation process has a very big impact on the quality of the project and usage performance of the liner which means the service life of the geomembrane liner is affected and also influence the following maintenance cost.  While we use our own installation crews, with full thought to this, try to use skilled labor on the project. It’s important not to stress the liner during installation. If it’s going to be buried under a layer of soil or sand, this needs to be done, not putting weight on unburied parts of the liner. And if the panels need to be heat-welded in the field, this needs to be done well. To make it happen, skilled labor is necessary. You don’t want the careless workers to dig a hole in the liner or leave a seam on the welding joint.

Your geomembrane liner must be maintained in order for it to continue performing at its best. The amount of maintenance necessary varies from one geomembrane to another. Even though the HDPE geomembrane liner is high tensile strength but time occurs problems are caused by environmental stress cracking during the lifespan of your geomembrane, meaning you might have to replace the geomembrane before seeing a return on your investment. So regular maintenance is essential to cost to avoid usage problems and extend the service life of the geomembrane liner.

Average lifespan should also be taken into consideration during the whole project time. A geomembrane possessing a stable performance record for over 50 years might cost more at the start, but the return on investment will be greater than that of a geomembrane with a lower initial cost that will only last 10 to 15 years. A longer lifespan means a higher yield rate.

Estimating the cost for a large pond liner requires more than choosing the cheapest material per square foot. All factors of the project need to be considered, including the size of the pond, the usage of the pond, lifespan expected, slope and depth, material character, and also shipping cost to the project location, labor handling the installation, and maintenance cost.

The cost-effectiveness of the geomembrane liner is a component of its true pricing. You want non-toxic material for a fish pond, and you want something that won’t degrade with a long-term project. If the ground is less than ideal, you may either need to use an underlayment to protect the liner from tearing, or you may need to cover the bed with a layer of soft soil or sand before setting the liner in place.

, you should not decide on a geomembrane liner based on the initial cost. The extra expense will sneak up on you, resulting in a greater lifetime cost. Taking everything into consideration is the proper way to avoid unexpected costs and get the project under your control. Make sure to do your research and weigh your options to find a product that fits both your performance and budgetary requirements.
