How to build a concrete slab for shed?
Looking for some advice and information on getting a concrete slab down for a 3x3 or maybe even a 4x4 shed. After using a couple calculators found on the web they say i will need approx 100-150 x 20kg bags of concrete, is this correct? or does it seem excessive for a 3x3-4x4 100mm slab, this means it will be $1000-$1400…
