We had a deep pond in our garden which we have filled in (due to danger of small children falling in - we kept the walled fish pond which was safer).
Anyway, we now have an earth patch which we want to concrete over. Should we put gravel down first, sand down first or just mix up a load of concrete and pour it onto the earth?
Any advice welcome. I also thought about inserting some ornamental tiles or bricks, is it best to do this when the concrete is starting to go hard or immediately after pouring it?
Thanks very much
