Most Popular Fish-Safe Pond Liner for Small Koi Ponds and Water Gardens

The first thing you want to do is make certain the pond liner is fish-safe. That is vital. Fish-safe liners come in a number of thicknesses which are made out of different material. The most popular for a koi pond or water garden are 45 mil EPDM rubber pond liners. These liners are very thick - about 1/8" and so are very pliable and 'rubbery'. They remind you of a bicycle inner tube, but thicker. They can be found in various sizes with dimensions that are divisible by 5'. For instance, a 10' x 10' pond liner would come pre-boxed and prepared to ship. Pond liners up to 400 square feet (say for example a 20' x 20' liner) could be shipped via UPS. Larger, 45 mil EPDM liners which are heavier and packaged differently, require shipment via motor freight and can be found in rolls with the largest size being 50' x 100', all in one piece. These rolls are typically transported to the pond site with a front end loader with a fork that fits into the opening of the roll that the liner is rolled on. These liners can weigh 1,500 pounds or even more and once at the website, are rolled out near the pond's edge and strategically placed in to the excavated area.

HOTTEST Fish-Safe Pond Liner for Large Fish Ponds

There are a couple of options for those people who are looking to build a large fish pond or water garden where they might require a liner larger than 50' x 100'. In this case, the 2 2 most popular options are to get 2 or more rolls of the 50' x 100' 45 mil EPDM pond liner (or whatever size you need) and splice them together (see below for splice information) or buy a different kind of liner that comes in a much larger size and is manufactured all in one piece! I'll explain the two options further in order to decide which sounds probably the most appealing to you.

How exactly to Splice Two 45 mil EPDM Pond Liners Together


Although you can find step-by-step procedures that certain must follow to splice 2 pieces of 45 mil EPDM liner together, in a 'nutshell' what you need to do is lay both pieces on an extremely flat surface such as for example plywood or for larger applications, a set parking lot or driveway. You unroll each liner and carefully overlap one edge of the liner on the edge of the other liner. Ideally, this overlapped area should be about 6" wide for the length of both liners. A two-sided, sticky, EPDM pond liner tape (called a splice tape) is then rolled out onto the edge of the bottom liner which has already been carefully cleaned and primed. The edge of the top liner, which has also been cleaned and primed is carefully laid onto underneath liner. The spliced area (ie; overlapped area) is then rolled with a roller to create a tighter seal. In addition, an EPDM pond liner cover strip that is approx. 6" wide and contains one side that's sticky, is then adhered on the seam joint from the 2 2 spliced liners. Next, a bead of rubber caulking made specifically from the manufacturer who created the 45 mil EPDM liner, is ran along both edges of the cover strip. After 24 hours of drying, the liner can then be moved into place. It is possible to splice as much pondliners as you want together so as to create the right size of liner you will need for your application.

The advantage of having a large, 45 mil EPDM pond liner is that it is a heavy-duty liner and is 'rubbery' gives it greater flexibility and 'forgiveness' with any protruding rocks which could surface from the already prepared and raked out area for the pond. The downfall of utilizing a 45 mil EPDM pond liner for larger applications is that it's heavy which requires higher shipping costs and more manpower to move it into place.

24 Mil Woven, Polyethylene Pond Liners

24 mil woven, polyethylene pond liners are excellent liners for large ponds whether they're for large koi ponds, water gardens, large fish ponds or for aquaculture uses. They provide great strength and are light weight. Unlike other polyethylene liners that simply stack layers after layers on top of each other in the manufacturing process, this polyethylene liner is woven together which gives it more strength. Another huge benefit to this liner is that it's tailor made to size and may come all in one piece around 65,000 square feet! https://yusuf-christian.blogbright.net/build-your-personal-backyard-pond-whats-the-most-affordable-method for a big pond application!

Unlike PVC pondliners which are available for large fish ponds, the 24 mil woven, polyethylene liner doesn't require 12" of soil along with it to safeguard it from UV rays. This specific liner is UV stabilized so that it can last for years! Because they're lighter weight, they are cheaper to ship and require less man power to maneuver. They are only offered in larger sizes and don't come pre-boxed like the 45 mil EPDM liners do. Each 24 mil woven, polyethylene liner is tailor made to size in increments of 5'.
