3-dimensional liner

[Steve Nguyen]

what do you think? anyone use this before? it's from http://www.pondtechnology.com/pages/butyl.html I think it's great. no corner folding is needed. don't know how much it cost though.

30 MIL AND 40 MIL BUTYL CUSTOM THREE-DIMENSIONAL LINERS: Where folds are not acceptable, such as for formal reflecting ponds, we can fabricate three-dimensional rectangular liners with vulcanized corners. We can also fabricate three-dimensional L-shapes and cylinders, but these can be very expensive and may require long lead times. The walls of the pond must be accurately formed of wood, masonry, or concrete: three-dimensional liners cannot be used with soil or stone walls.If the liner is to be wrapped over the top of the pond walls, order the liner at least six inches taller than the pond. Cut four small round holes corresponding to the top corners of the pond walls as shown. Then slit the corners to make four side flaps.When the flaps are folded over the rim of the pond, there is a notch at each corner where there is no rubber. This can be filled in with a small square of uncured repair tape. Clean the rubber with our cleaner/primer or with naptha, position the tape so that it hangs over the pond two inches, and form the tape downward into the corner (the tape is stretchable).A three-dimensional rectangular can also be fastened directly to the wall of the pond. Mark a line approximately one-quarter inch above the planned water level. Cut and fasten our black termination bars just below the line using the screws provided (if fastening to masonry, use plastic inserts). Mark the ends of the bars and remove them. Clean the wall and apply our termination bar tape below the line but leave the release tape in place. Position the liner, making certain that it extends completely into the bottom corners of the pond so that it will not stretch when the pond is filled with water. Then remove the release paper and carefully press the liner into the tape. Finally, re-attach the termination bars.

Hi Steve

I have a 3D EPDM bag in my winter/quarantine pond. No folds where dirt can settle or small koi can hide or even get stuck!

I was there last year after Koi America and they were assembling a liner. Conscientious and careful, these are very likable folks, that's for sure. I was entirely pleased with the dealings I had with them.

How much though, I don't know. Another question, how much to ship it?

for a 11L x 6W x 5D, it's $1300 and cannot be installed without a sturdy or hard walls such as concrete or wood structure. that's stiff.

About $2.50 per square foot. A little pricey - but someone has to pay to for the seaming labor. You know, you can get a seaming adhesive system for EPDM. Ask for it at a commercial roofing supply. Its pretty good, but not fool-proof. I do not think you can heat-seam EPDM so this may be what they are using with the product you mentioned

For high density or low density polyethylene (HDPE and LDPE) you have to buy a extruder heat seamer which is sort of out-of-reach for the hobbyist. There are a few companies making custom-fit HDPE liners as well. It's less expensive, but the polyethylene does not stretch at all so you need to be very exact with your dimensions.
