Hello...I live in southern Ontario Canada and I just built a rectangular concrete pond. 8ft long 3 feet wide and 3.5ft deep. I am looking to waterproof the floor and walls but I want to make sure I use the best product out there. Any suggestions would be appreciated, thank you...

Hello and welcome!
Are you not going to have a liner?

Hands down fiberglass but at 3 feet wide thats not much of a viable option . Plaster is a possibility. If you had asked before you built I could have recommended a mix that is water proof on its own. There are also many products out there that are basicly a paint that can do the job.
Not sure how comfortable I'd be with your floor patch on the bottom toward the upper left side. if theres a hard dark line there could be the potential of a leak as it looks in the photo. I'd get that patched a bit better before waterproofing

No liner. Base is 5 inch thick and walls are between 3 and 5 inch thick
Base is 5 inch thick. The patchwork you see were just some small imperfections in concrete I was trying to smooth over. Pond is solid, no joints as I did it in 1 continuous pour
Yes every 12inches both ways
I would use Rapid Set mortar mix. I sealed a concrete block reservoir about ten years ago with Rapid Set and it has held up well. I applied it with a trowel.

Would you mind sharing the water proof mix you are referring to?
integral concrete is what your looking for While it is not a 100 percent a simple concrete sealer applied in thin even coats will do the job. You want to seal the poures of the concrete and block the air entrapment from allowing water in which in time can freeze or even in a place like texas the rapid expansion and contraction when the hot sun comes from behind a building or a tree. It's this that needs to be sealed to prevent water infiltration and rapid expansion pauking and scalding.
I ended up pouring another 2 inch concrete on bottom to smooth it out. I also did some research and found a 2 part epoxy product called Ramuc. It's used on swimming pools I guess. I called a pond store in Toronto and the guy there said they sell Ramuc for outdoor ponds...
I'd still look into plaster it has been the skim coat of pools for centuries. i'd imagin they even have an acrylic additive to the plaster. There are roman bath houses with plaster . or talk to a local pool company what they use for a top coat on a gunite pool.
Those coatings were 4 , 8 , and unspecified life spans. not something i'd want . though 2 part epoxy can be some damn good stuff maybe the unspecified might be worth it but i guarantee it won't be cheap

Excellent thank you. What is your opinion on the products like Pond Armor epoxy sealer vs the concrete sealer?
