Pond Liner Help

[lamluu]

I bought 20'x20' firestone 45mill pond liner on ebay .Open up and find out the thickness it uneven. There is 4 inches thicker space go across along at center whole piece ,it look like a seam but there is no connection line. so I see just like a 4 inches stripe thicker at center of whole piece . Do some one know about pond liner let me know that is normal or that go wrong .I want to return it but it is very heavy and cost for return will heavy like it self .THANK YOU

The liner should be the same thickness regardless of spot. You may have been sold second quality or a reject. Suggest you return for a full return then purchase from a well known company. Good luck.

Sometimes the larger size liners have a factory seam. I got a 25x25 and it had a seam right thru the middle.

It does sound like a seam - or more like a weld, where they melted two pieces together.

No big deal. Doesn't affect its quality. When you put it in the pond hole, arrange it so that the seam isn't in a position where you'll need to pleat it. Of course they're seamed here and there........so what?

Think of it this way, you got twice the thickness in a narrow band and you weren't charged double.

EPDM membrane is manufactured in 5 foot widths. These 5 foot wide rolls are then seamed to each other at the factory. This is why EPDM is only available in multiple widths of 5 feet. i.e. 10 ft, 20, ft 25 ft,etc.

Place I buy my liner material from rolls it off a huge roll. That stuff is seamless,be danged if I'd risk a leak with a seam. Having that in my liner would be a constant worry.

Firestone EPDM still has factory hot-weld seams. These seams are actually stronger than the actual liner. I have never heard of a factory seam failing. These seams are typically 4 inches wide as you have described on the liner you purchased. These are not factory seconds or rejects, but part of the normal manufacturing process.

I had seams in a few of my large liners also , it not a big deal

My liner has factory welded seams. No problems so far.

My liner was 50 x 50 and I've had no problems with it at all.

On pools I put liners in by heat welding, we then use liquid plastic called seam sealer to protect the seam and to help smooth the edge
