Frequently Asked Questions (FAQs)
1. What is the most flexible pond liner?
High-density polyethylene (HDPE) liners, also known as reinforced polyethylene liners, are one of the best choices for flexible pond liners. They offer even better puncture resistance than either EPDM or PVC liner, while weighing roughly one-third as much and being half as thick.
2. Is pond liner flexible?
EPDM Pond Liner is the #1 choice for water gardening because it is very flexible, puncture resistant, and long lasting. For lining large ponds, we recommend the polyethylene material because it is lightweight, easier to handle, and less expensive than rubber. Also, polyethylene liners can be made up to 60,000 sq.
3. How long does a flexible pond liner last?
To summarize, a rubber pond or flexible PVC liner can last for 20 years or longer as long as they are installed over a protective underlay and secured in place using the right edging materials and are protected against visits by clawed animals.
4. Are preformed pond liners any good?
It has mostly fallen out of favor these days, though, as preformed and flexible liners have gotten better and better (especially with regards to durability). A concrete pond requires the most work to install, by a great deal. It's hard, backbreaking work that requires more than a little bit of skill to do well.
