#Rigid pond liner crack
Surface freezing still adds extra wear and tear to the pond liner, increasing the chances of a stress crack that forms in a molded shelf or lip area. Despite being reinforced with fibers, fiberglass liners tend to crack more easily than plastic ones. The ice expands in all directions, putting a lot of pressure on even the toughest plastic and fiberglass liners.
Rigid liners are easily damaged by solid ice in cold climates where the entire body of water freezes solid.
When you know your rigid liner is leaking, the main technique for dealing with the damage is to replace the entire liner rather than finding the problem and patching it. If the liner’s in the ground, there’s no testing equipment to register the leak. You can set the rigid liner up above ground and look for leaks, but this can damage the shell since it’s not being supported by the soil. There’s no way to reliably test a rigid liner to see if it’s leaking or to find compromised areas. Many people buy multiple preformed liners and experience the same kinds of leaks with them until finally switching over to a flexible material that is more damage resistant. If you can’t find the leak in the preformed liner, there’s no way to fix it. Pinholes also commonly form in the weakest parts of preformed liners without any noticeable visual change. Since most preformed pond liners are small, these ponds can drain overnight before you notice a problem. The rigid material is prone to cracking so that it looks intact but is slowly losing water. Cracks and Pinholesįirst, the types of leaks that form in preformed pond liners are hard to spot when the pond is filled. Having to tear out the entire pond liner and replace it because there’s a leak is a wasteful, difficult, expensive repair. Leaks are never easy to find or patch, but it becomes downright impossible with the wrong kind of liner. When a leak develops in a preformed liner due to damage or age, it’s tricky to deal with the problem. However, choosing a preformed pond liner makes this much harder. With careful construction and the right liner, it’s possible to build a pond that doesn’t develop leaks for decades.
