The choice of pond liner is an essential element of any water containment project. Whether involved in farming, aquaculture, or another commercial end-use, the liner choice is an important consideration for its future longevity and function. The primary competitors are High-Density Polyethylene (HDPE) or Polyvinyl Chloride (PVC).
Shree Bala Hanuman Polycoat PVT. LTD. is an ISO 9001:2015 certified manufacturer of tarpaulins and will provide you with a broad and high-quality group of products and solutions across India, including top performing pond liners. So let’s discuss HDPE and PVC and hopefully assist you in your decision.
Why Consider HDPE Pond Liners?
HDPE pond liners exhibit superior strength and durability. HDPE (high-density polyethylene) is a strong material suited for large projects and harsh conditions. HDPE also provides excellent UV and chemical resistance.
These qualities make HDPE great for outdoor applications and diverse types of water or industrial waste. Choosing an HDPE Pond Liner Manufacturer is choosing an established, reliable, and long-term solution. A lot of HDPE installations are accomplished via thermal welding, allowing for strong, leak-proof seams.
The Advantages of PVC Pond Liners
PVC pond liners have a lot of flexibility. As a synthetic liner, PVC easily accommodates for irregular shapes and contours, making it popular for more complex and smaller designs. PVC is usually cheaper up front, which sometimes is a big consideration when the project is budget constrained.
In many scenarios, it is also easier to manipulate in part due to the flexibility it provides during installation. Long exposure to UV can, over time, make PVC brittle which can affect the longevity as compared to heavier gauge materials.
HDPE vs. PVC
- Durability: Generally, the most durability is with HDPE because of puncture, tearing, UV light, and chemical resistance. Most HDPE Pond Liner Suppliers also will provide a much longer life expectancy. While PVC deteriorates more quickly than HDPE in sunlight.
- Flexibility: PVC is more flexible, and it can allow for complicated shapes without fabricators and special tools. HDPE is quite a bit stiffer, and for larger installations, usually has to be professionally welded.
- Chemical resistance: HDPE has the best chemical resistance so it is suitable in a wider and broader range of industrial and agricultural applications than PVC. Some grades of PVC have lower chemical resistance than other grades.
- Cost: The upfront costs for PVC may be lower than HDPE. However, when you factor lifetime costs, HDPE is a good bit longer and lower maintenance may provide better value over a longer time.
Conclusion
Which liner is best is dependent on your requirements. For large scale holding of water, and for industrial containment, or where chemical resistance and longevity is paramount, HDPE will almost always be the best choice. For smaller, swimmable decorative ponds, or when cost and deal ability are the most important variables, while also considering avoiding direct sunlight, PVC will suffice in these situations.
