Has anyone thought about doing this? Its fairly inexpensive, easy to install and with the fiberglass tape and some thinset it would be stiff as hell and should allow you to use drylock or something waterproof like it. (Antihydro for me) and u could even tile the inside. Any thoughts? This stuff is $10 bucks a sheet. I've used it alot in other applications.
1/4" Durarock inside plywood tank
- Thread starter cichlidtank
- Start date
I will be using 1/2" durarock laid over top of 1/2" plywood for my build. I like the adhesion factor better than just plywood.
how do they make swimming pools, every time i go to an aquatic center im always visualizing if it was converted to a pond for my red tail cat..
just need that lotto ....

Tfg had me convince on this method a few years back. Main thing that stopped me is that its prob not too mover friendly. If your building a giant that would never be moved it prob wouldn't matter
Yeah thats a slight issue for me as well. Though the opposite. I want to build one from solid concrete but when i sell the house im not sure the new owner would be interested in a 500+ gallon tank. So i may go this route. That and building it up off the slab is simplified.
Anyone got links for some builds with 1/2 cement board? I must be no good at searching. Thnks.

Thought i might give some info. On this anti-hydro ive been mentioning.
It is a liquid additive for concrete/mortar.
It makes the cement nonshrinking and 100% waterproof and also is supposed to seal in the alkilinity that traditionally leaches from concrete and that is the only aspect i have not directly tested though ive observed that the water in a pond construction doesnt appear contaminated and that no white leaching.g is present as it would be otherwise ive just never tested ph levels as these were fishless projects.
It is actually used in concrete tank construction and makes the cement usda certified food grade. (Dont try to eat it though)
One gallon is around 25$ and is more then enough for most tanks built here. Ive used it in the construction of a pond that was 1600 sq.ft. in size and averaged 30 inches deep with two large seperate areas and two small seperate areas(with waterfalls falling from one area to the next). So it was a lot of sq. Ft. Overall with the surface of the water measuring in at aprox. 1600 sq.ft.
It was applied in a mortared stucco fashion over a concrete base that was existing from the original build in 1920 otherwise it could be mixed directly into the concrete itself. The stucco portion took aprox. 5 5gallon buckets if memory serves me. There was only one crack that ever developed and it was more of a seperation in a vertical area where it was applied at a couple inches thick it seperated from the sitting area at the top of the wall about a 1/4 inch but never actually cracked. I just poured in a thin mortar mix with the antihydro nearly replacing all the water in the mix and its been perfect since.
Anyways my idea is to build a plywood tank with 1/2" durarock with seams taped and thinsetted then v-notch thinset the entire inside covering that with a stucco applicaition of 3/8" all mud mixes heavy with antihydro. This could be died to the color you may want but just for extra insurance and to keep moisture at all costs from getting at that plywood im gonna coat it all in drylock.
I am gonna be testing this in very small scale soon without drylock and will post a thread about that. Hopefully start building the tank next tax season.
