Hi
I need to lay a base for a new shed i wish to erect on my back garden, i intend to used existing paviers which i've removed from an old patio. The site for the new shed is currnetly used 50%as a vegatable plot which is well cultivated soil and 50% uncultivated (estimating 5+ yrs) firm soil with clay sub-soil.
What i'm thinking is where its is cultivated i need to remove the topsoil down to the clay sub-soil and fill with hardcore/rubble and top with 100mm scalpings or type 1 fill before my 50mm bedding sand cement mix. My question here is where and what is the cheapest fill material i can get and is suitable to build up the level? (its about 1 1/2 spades depths to clay sub-base) so about 300mm of fill needed before the type 1.
The area which is quite compact will i be ok just to remove the top 100mm of soil and just lay the bedding mix to level the paviers or should i remove extra soil and incorporated a layer of type 1 fill also. what thickness would you suggest (in light of the 300/400mm of fill i think i'll need for the cultivated side)??
I don't mind the time/efford digging just want to keep the cost down and do a propper job.
Cheers in advance.
