concrete pond
 
Hey my buddie and I are thinking about putting a concrete pond in his backyard. I have done tons of foundations but never something like this. Does anyone have any pictures of how to form this? Or do I pour it like a pool? The pond we are gonna do is going to have a raised edge so you can sit on it, but it has to be one continuous pour for the bottom and sides, and I cant imagine how to form the inside of the pond... Thanks for the help.

I'm on my phone right now but we should stay in touch. I'm doing something right now in my backyard and we can trade notes.

I'll touch base with you this evening

That is how Jethro and Jed would go about it but they had the money to build their cement pond.

A plastic liner or clay is a lot cheaper,and much easier to work with that concrete.

He is gonna have turtles in it so we wanna go with concrete cause of durability, plus we are contractors so why go the cheap route?

If you could do it in two pours you could use "water stop"for the joint control.
We use this stuff all the time for containment dikes and it works believe me.
Just a thought.

Are you dead set on formed and poured?

I am going with CMU drystack, core pours, rodded with a coat of Surface Bonding Cement each side (I couldn't wrap my little rat brain around forming a 4' high wall)

How are you planning to waterproof?

Ravenworks 05-21-2012 04:16 PM

The problem with doing it with one pour could be head pressure.

thehvacguy 05-23-2012 03:52 PM

What do you mean by "Head pressure"?

thehvacguy 05-23-2012 03:54 PM

We are not dead set on formed and poured, we just want it solid, are gonna put bricks around the edges so we can sit on it. I guess dry stack would work, I just have to achieve a 19" deep border so we can sit.

What I meant was while pouring into the top of the form the concrete will blow out through the bottom. I have since rethought this because you probably won't be using a vibrator.
As for the bricks,I would stick to concrete because you can clean it to keep it sanitised.
You could pour the floor with a curb,and add the water stop and form up from there?

The water stop sounds like a viable solution at this point. How durable is it? Can one of you guys post a link to a website for the water stop? I honestly have never heard of water stop yet in my career, this is pretty cool.

You will have to form a key-way in the curb,which is nothing more than a square piece of wood or a shallow V piece.
You can use a polyurethane sealant to glue it down,on verticals you will have you add fasteners to help hold it until the poly sets.
We drill a 3/16" hole,insert a piece of tie wire into the hole and drive a double headed nail in afterwards.
Any masonry supplier will have it.

TRUEPRO 05-31-2012 09:32 PM

Pour the slab/footer. Build with masonry, trowel hydraulic cement on the bottom and sides like you would a pool, leave a sawtooth in the masonry to catch the concrete you will pour for the border and the sitting area? Any concerns with it not holding water use the poly urethane sealer generously more then once. ALL very inexpensive products that are readily available.

Just a thought. The other ideas seem viable as well. GL
