It's a long one but I'm hoping someone can help, please.
We had a semi raised pond. We've dismantled it and are left with a hole about 4ft deep. We've broken up all the rubble from the sides of the pond to put in and the plan is to pave over it.
I have several questions.. 1. Do I need to use a compactor to make it level before I pave it? I don't want to get subsidence, I plan to out the play house over the top.
Do I need to put anything in with the rubble such as sand or small hardcore?
I'm guessing I need to use a soft concrete for the slabs to enable drainage?
Why did I start this?!!
Any helpful advice will be greatly received, thanks.
