Filling in a pond

Postby Suffolk Mum » Mon May 12, 2008 6:37 pm

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

If you haven't completed the task yet........
How you approach this dependes on the final usage of the area.
If you just want to use it for walking on or having a seating area then about 2'' of 20mm gravel first then 3'' or 4'' of concrete.
Wait for this to set then put your tiles down, setting them with a mortar mix of sand and cement or ready mixed mortar in dry form.
If you intend to park a car as an extreme example, or have some other heavy usage of this area, then the garvel should be 4'' deep and concrete should be 4'' deep.
If you had a load of old rubble like broken bricks, then this can be used in place of the gravel which can cost £80 a tonne. Just level them off as best a you can.
You need to take into account the final level (2'' or 4'' gravel plus 4'' of concrete plus the thickness of the tiles or blocks on top) and may even have to dig down further.
A lot of concrete is usually needed, even for small jobs.
