Concrete collars

[bwgan]

Hi guys,

Just wondering if anyone has had any experience of building thier pond using the above method? If so how did you get on with it? What were the dimensions of the foundations? How deep dig you go down past the collar?

Cheers

Hi Paul,
I used that method for my growing on / QT pond, the dimensions will depend on the finished size of your pond and how high the walls are going to be.
We have a book in the club library that describes this method of building a koi pond, it would be worth reading before you start.

I used a concrete collar on my liner pond.
Trench was about 1' x 2' deep. It's essential that the walls are verticle, and not sloped in or out.

The pond itself should be about 6' deep, so the actual excavation will depend on how high you intend makingn the raised walls.
e.g. 1' walls, then only 5' excavation (ie about another 3 feet deeper than base of concrete collar).

Send me a PM with your e mail address. I have a Word document with photos of the various stages of my pond build.
This link to the Richdon BB may help. Check both pages as the photos are in the wrong order.

Dave I remember you mentioned it when I spoke to you when we met.

Hi Paul,
Within the book I have referred to there is a section about pond security in respect to safety for kiddies,this also will dictate the height of the walls, and then how deep the footings require to be.
