Liner vs Liner
Our Money Is On EPDM
Its no secret that we prefer liners to preformed shells. Well order them if you insist but we wont clutter our store with something we dont believe in.
Liners allow you to be more creative with the shape of your pond. You must conform to the manufacturers idea of the perfect pond if you use a preformed shell.
None that I know of come in three feet depths - a must if you want to offer your fish protection from predators.
It saves you no time to put a preformed pond into the ground. In fact, it costs you another step to backfill to fit the shape of the shell.
You cant put maintenance-saving bottom drains in the hard plastic shells.
When the ground shifts (as it often does) the form will shift with it and your carefully constructed leveling job will be for aught.
Forget putting that beautiful large boulder on the lip of the preformed shell. It will crack under the weight.
And when it cracks let us know if the patching material stays on for more than a month.
If Ive steered you away from purchasing that seemingly easy to install preformed pond shell good! Now you need to decide what kind of liner to install. We have our preferences on that too!
As far as were concerned, there is no choice. The EPDM 45 mil rubber liner material is the only liner we carry. Oh, we could carry them all in fact we did the first year we were open. We found problems with all the others and simply chose not to deal with any more problems than we had to. This was the same philosophy we used when we chose what brands of pumps to carry, but thats another story
If someone offers you an irresistible deal on 45 mil EPDM resist it. We have seen where folks are selling 45 mil EPDM rubber liner material for CHEAP prices and found out that its used by roofers and has been treated with some kind of chemical (cant remember the name) that is very toxic to fish. Be sure the material is fish safe.
45 mil EPDM is thick and its pretty heavy. We dont recommend the 65 mil EPDM with attached underlayment. Its the devil to work with and if you have to fold it in the corners, etc. (and most of us do) the folds are quite ugly and bulky. Its best to install separate underlayment.
Steer away from Permalon. Its possible that someone has told you that Permalon is the best liner for a number of reasons. Like I stated earlier, we have carried it and found problems with it! Its plastic. It has ridges that do not allow for easy patching if you get a tear in it which you probably will because the liner is not as thick and durable as EPDM rubber. It is known to have problems where the seams are glued. Its stiff and very hard to work with and its easy to puncture. If someone does tell you that Permalon is the best thing since sliced bread beware. It could be that the manufacture gives excellent pricing incentives to the dealer.
Lets not dwell on negatives and switch back to the virtues of 45 mil EPDM rubber liner. It comes in a wide selection of widths. We keep the following widths in stock: 5.5 ft. / 10 ft. / 15 ft. / 20 ft. / 25 ft. / and 30 ft. Larger widths are readily available for special order. Widths become very important when youre paying by square foot.
45 mil EPDM forgives. If you dont get it tucked just right into the corner of your hole the rubber stretches with the pressure of the water against the pond wall and fills the void.
EPDM carries a 20-year warranty. Because it is thick it is also very heavy. That could be the only negative about it! Its well worth the extra labor to install.
The liner is the skin of your pond and will be around for a very long time. Dont cost yourself trouble, money and aggravation by trying to find a deal on this particular product. After all, what good is a liner that doesnt hold water?
