Fish pond construction, brick wall strengths etc.

[Boosted LS1]

Hi, I've got a pond sunk 3 feet deep into the ground at the moment and the floor around it is concrete maybe 5" thick. The triangular pond measures 10 ft x 10 ft and is a bit longer on the third side. I want to add a wall 2 ft high and add maybe 18 inches of additional water. I think that a double row of bricks tied together and bonded to the concrete should be strong enough to contain the additional water but some builders don't seem to know if this is the case or not.

Does anybody know where I can check if my plans seem reasonable or doomed to failure or has anybody built a similar pond? Thanks.

Thanks for the replies and links. I've been over to the Koi forums, what a fantastic place to look around.

Well, it seems to be that an inner wall of concrete breeze blocks and an outer wall of brick will do the trick. In fill between them with a concrete mix. Or use a double course of bricks tied together. Both methods have worked on similar ponds.

^Good build link.

The builder laid the first row of bricks this morning and we've decided on a double course of bricks tied together and finished off with double bullnosed bricks on top. Should be finished in a couple of days .
