Western Environmental Liner can prefabricate very large pond liners in one piece. This is made possible due to Western Environmental Liner’s unique machines that have the ability to weld very wide widths and infinite lengths.


Western Environmental Liner also has winding and loading equipment that allows for large pond liners up to 8,000 lbs in weight or more as well as liners as large as 200,000 square feet. When needed, Western Environmental Liner’s large open factory space can also be utilized.


Being able to make very large pond liners allows for many large ponds to be lined with just one geomembrane liner panel with all pre-welded seams. These preformed pond liners often produce the best results.


When there is a weld seam failure it is most often a field weld failure due to the fact that factory welds are very consistent if advanced factory equipment is being used.


Outside welds also have many other factors to contend with that factory welds do not, such as uneven ground, wind, rain, inconsistent power sources and less sophisticated smaller scale welding equipment. 


Although our turnkey options are quite affordable compared to most other installation options available, being able to make a large pond liner in one piece normally lowers the overall liner installation costs and also lowers the risk of having a possible leak.

1. Do I need underlayment for a pond liner?

Yes. A geotextile underlayment is ideal to protect your liner from tearing or puncturing under the considerable weight of water in the filled pond. While the liner material is selected for its impermeability, the underlayment is chosen for its ability to withstand puncturing from any rock or roots that may not be obvious prior to lining the pond. See our guide to Geotextile Underlayment.

2. How much should a pond liner overlap?

For large ponds as a general rule you need an extra 5 feet of liner at all edges to bury in the securing trench that holds the liner edge - larger will require more overlap, smaller less. Estimate the liner size using our online pond liner calculator and make sure that the edges of the material are fully covered so no wind or weather elements can work under the liner. Plan to unroll and See our Large Pond Liner Installation Guide for all of the factors to consider.

3. Can you join a pond liner?

Installing a pond liner from multiple pieces is a very skilled task. Welding in the field is one of the principal causes of failure - much depends on the installation crew. The best weld happens in the factory using precision equipment in a controlled environment, to create the custom liner you need. See our guide to Installation Tips and Pitfalls with Pond Liners for these and other considerations.

4. What is the best liner for a pond?

Reinforced Polypropylene (RPP) is best for smaller fish ponds, while Reinforced Polyethylene (RPE) is best for larger fish ponds. And not just for fish but for any kind of water-retaining pond, in general RPE is often better than HDPE for pond liners. Many retail providers offer EDPM which is a synthetic rubber, but this material can usually be outperformed by PVC, RPE and HDPE materials as pond liners.

5. How long does a pond liner last?

Every pond liner should give good service for 20 years. Look for a materials provider and an installer who will offer a 20-year warranty. This is the hallmark of quality, and your only recourse if the liner fails before its time.
