Thread: Concrete pond build

Hello all,
I’m planning on building a concrete pond. Just at the initial planning stages, but looking for some advice to see if I’m on the right lines or not.

So the pond will be a rectangle 2.25m wide, 5m long and 1m deep. So 2474 gallons I believe

I’m planning on doing concrete walls and base, with MDf to make a pre form to make the walls shape. My reason for this is that I own a concrete mixing truck, so cost of the concrete isn’t really an issue.

To begin with I’m going to dig and pour footings which are at least 4 inch deep. (Do I even need footings though?)

Then make MDF walls 1 metre high, allowing concrete to be poured internally at 6 inch thick. All MDF forms will be heavily strengthened and will be putting rebar mesh throughout the internal, any ideas how thick rebar needed?

Only 2 walls will be seen afterward, and will be faced with something, so doesn’t matter to much about marks on the concrete wall. I do also have access to a concrete poker for vibrating the concrete as we pour it into the walls.

Not to sure how the deep the concrete base will need to be? And guessing it will need rebar in it also.

Was also considering when I do my footing to stick some rebar in there, so the wall can adhere to if afterward.

Once that’s all done, I was going to line the pond with a thick pond liner.

Will this even work? Have I missed anything major? Any advice is very welcome.

Apologies for the long message, hope it all makes sense

Yeh, I would definitely consider going a bit deeper if that would help the fish. Thanks for the advice

hi
No mention of filtration, bottom drain to ? skimmer to ? returns

Morning Keith,

I was planning on buying a suitable filtration system, to be honest I hadn’t considered a bottom drain or skimmer. But will do some research now!

What sort of ground are you digging on? This dictates a lot about how to construct the pond.
