Choosing the right pond liner is one of the most crucial decisions to make while building a pond. And with variety of options available, it can be a tricky one too. In modern times, the two of the most commonly use pond liners materials are HDPE (high-density polyethylene) and PVC (polyvinyl chloride). In this article we will discuss about the differences between the two and compare them on various parameters to help you make the perfect choice.
- Difference in Construction
The biggest difference between HDPE geomembrane pond liner and PVC pond liners is the materials used. HDPE is high-density polyethylene, a thermoplastic polymer based on petroleum, which are welded together for being used for different types of ponds. PVC, on the other hand is polyvinyl chloride, which results in pond liners with smooth surfaces. Unlike HDPE, PVC pond liners are generally glued, and hence, they are not apt for exposure to direct sunlight. Hence, if you live in tropical or hot climates, a HDPE geotextile pond liner is the better option for you.
- Applicability
HDPE pond liners offered by Emmbi are widest at 13.5 ft, which gives them a wide range of applicability. They are more suited to large scale commercial usage like agriculture or fish farming. Plus, the novel technology Emmbi uses like ProTex and Habitech makes these pond liners perfect for exposure to harsh climates. On the other hand, PVC liners, because of their lower resistance to exposed sunlight, have a limited use. They are best suited for small ponds, and using them for large scale commercial purpose may be quite cumbersome.
- Durability and Strength
Made from high-strength thermoplastic polymers, HDPE pond liners are sturdy and durable, which can stand the test of time for a long period. There are highly resistant to UV, oxidation, chemical reactions, the physical wear and tear. Also, as they are welded and not glued, the chances of leakage and seepage reduces significantly. The organic growth of algae on the surface due to the Habitech technology prevents evaporation and the multi-layer protection from ProTex makes it durable. PVC pond liners, on the other hand, are flexible but less resistant to UV. Prolonged exposure to sunlight causes it to degrade.
- Long-Term Maintenance
One of the most important factors you need to keep in mind while selecting the geotextile pond liner is the amount of maintenance it would require. Generally, maintenance involves manpower that will involve costs. HDPE pond liners require little to no maintenance even for a longer period of time, because the ones produced by Emmbi are designed to mimic the natural environment. The welds are stronger than adhesives, and the resistance to climatic extremes ensure that you don’t need to check on the pond every now and then. Comparatively, PVC pond liners require much more attention, especially if you’re using them for fish farming.
