I have high expectations for this pond liner. I haven't installed it yet, but soon. This will be the 3rd liner I'm going to install for my pond in 3 years. I have a excavator coming next week to dig a drainage Trench across my entire property line. The problem i keep having is hydrostatic pressure from ground water is getting in under my current liner. During heavy rain water gets in under my liner lifting it up where the pond water hits my overflow drain pipe and empties my pond. I have 17 goldfish and 10 koi, almost lost all of them last rain storm.
The liner I purchased from you is by far the thickest, strongest and most expensive. The box it came in is ridiculously heavy, I'm very pleased with the quality so far. Im going to be over Engineering the pond starting next week. Once I get the new liner installed I will be publishing another review.
This sounds like a hassle for you and nightmare fuel for your fish! I'm glad you didn't lose them. Moving forward, it may be helpful to add some weight at the bottom of your pond. An extra piece of underlayment underneath a few large rocks should do the trick. Give us a call if you want to run any ideas.
