Concrete ponds?

How to build a concrete pond?
i'm planning to build a backyard fish pond and making it concrete but i do not know if that is feasible that is why i keep on searching for best answers for that.


  • Instead of concrete, think about using 40 mil butyl rubber liner. Concrete is brittle, cracks easily, cannot be repaired and leaches lime. The flexible liner has at least a 20 year guarantee and is easy to install and work with.

Letters, we get letters

Question about koi pond construction:

I have had several propositions so far this year for a pond. I know where I want it, just not entirely sure how to build it. I want it 5' below ground and 2' above ground, with a viewing window facing the house. I want it right behind my swimming pool so I can almost literally swim with my fishes.

The offers were from two builders in particular, one wants to do gunnite and the other will use EPDM, both will do it over reinforced concrete block. One wants to build a filter shed in the corner of the yard, and the other wants to put a filter "room" below ground next to the house. It is for koi so it will have to have a bottom drain, or two, and the biggest filtration I can afford. I also will, being in Florida which is aka predator heaven, screen it in with my lanai and use the same patio paver blocks around the pond area to match the rest of the
deck area. What do you think? Have I lost my marbles?

Pondlady sez:

I think your plans are over the top!
Oh, one thing. Often swimming pool builders have pond
We both know all the problems with concrete, especially in FL
where you are pretty close to sea level. Might want to find out your elevation before doing gunnite.
The filter room below ground can make it difficult to access
when things need servicing.

Answer to pondlady's question:

One gave me a wonderful price for Diamond Brite. What do you know about using this in a pond? I have the same thing in my pool, which is just a finish as far as I know, over concrete construction.
I am above sea level here and the ground is graded so that my property is about 4-5' above the roads and fields around the area. They have to do that because of the septic leachfields I think. Anyway, I am building it 2' above ground to be on the safe side. I have also spoken to the other guy, a pond builder who is expert with koi ponds, to do the installation of the filtration equipment. So these two guys will work together on it to assure me of the best my money can buy.

Pondlady sez:

I don't know Diamond Brite, but think it is just a brand name for a finish, just as you mentioned.
Your pond sounds as if it will be divine. Please send pictures during and after construction.
