HI
Im planning to extend my concrete slab for a new shed and have a few questions.
The size of the new slab is 2.2m*2.6m * 130mm deep which i think is 0.75m3
1) How much ballast and cement bags do i need to buy? Was planning to buy 40 ballast and 10 cement
2) Do i need to leave a space between the new slab and the old one?
Really appreciate any advice
