Afternoon all.
I'm currently building a patio in the back garden, its going about 3m from the house and across the back of the house.
The house is on a slope so the back door is about 1m from the ground at minute, they means the patio will require an awful lot of sub base, approx 20 ton if I've done the calculations correct.
I've already split the patio into 2 heights to try and reduce the amount of sub base needed, and planning to have 1 or 2 steps to the back door.
However, years ago my local council filled in a subway with polystyrene and put a road and paths over the top of it.
So can a type of Extruded polystyrene be used to fill in instead of sub base?
Many thanks.
