FAQ:

Q: Are there any problems with a rigid pond liner?

A: However, like many other hobbies, pond keeping can slowly enthrall a person. Over time, you may desire a more advanced pond, such as a koi or goldfish pond. The problem with many rigid pond liners is that often times they are simply too shallow to properly control the water temperature for fish.

Q: Can a preformed pond liner be placed on the ground?

A: Still, some people like the clean look of a rigid pond liner. In the case of using fiberglass preformed pond liners, an important advantage is the ease of installation. Because fiberglass is quite rigid, the pond can be placed on the ground and filled with water straight away, with no other support necessary.

Q: What are rigid drop in liners used for?

A: Rigid Drop-In Liners are used to retrofit existing tanks or structures to significantly prolong the lifespan. FLSI will typically send a field tech to measure, if drawings aren’t available or the tank/structure has altered in size from the drawings from corrosion.

Q: Which is better plastic or fiberglass pond liners?

A: Plastic liners are less expensive than fiberglass liners or box-welded liners, but must be fully confined inside the ground to prevent the liner from flexing, and as a result, cracking. In contrast, fiberglass liners need no confinement whatsoever and can even remain freestanding on the ground while filled with water.
