The garden was dug out with a Kabota mechanical digger and this was done by a contractor. The side gate and one piece of fencing was removed to make access.
The base was levelled off, A142 reinforcing mesh was put in place and then six inches of concrete was laid.
For the first three layers 18 x 9 x 4 inch concrete blocks were used and these were laid as shown here. The space behind the blocks was then filled with concrete giving a wall of at least nine inches wide.
This website started with a
booklet which I made up originally for the help of those members of the BKKS
- South Wales Section who were intending to start building a koi pond, and as the website has expanded more information and articles from other people have been included. This
is for general guidance only, and we do not take any responsibility for problems
that might occur by following these ideas. It is important
that you check out everything in your area, and check on local laws and rules
that may apply.
