Pond construction

Ron's pond 8. Building up the outer walls

These photographs show the construction of the outer shell. As before, the outside of the concrete blocks have been painted with a bitumen type product. This prevents moisture permeating the blocks and attacking the fibreglass finish from behind. In this case the bricks have been chosen to complement the house style. In total 800 ‘pre-war Cheshire common’ bricks were used in the construction of this wall.
I had previously dug out the footings for the wall and used timber and a spirit level to provide a guide for the concrete that was added when the base was poured. Having a level foundation to work to made my task far simpler although not being a builder it took several days to construct the entire wall!
The front wall will be around 30” high therefore to ensure a solid construction a larger than usual cavity has been left between the blocks and bricks. A concrete mix poured into the cavity ensures that sufficient strength exists to resist the water pressure. When building the front wall in particular it is essential that the foundation on which the wall sits is solid and of the required depth to ensure wall integrity. A final row of bricks on top of the inner block wall will bring the level to the required depth. The final photographs shows the infill tapering off at a point where the soil in the borders will provide adequate support.

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.
