I'm preparing ground for concrete slab. I've now dug my slab area (10m x 6m), and 225mm deep footings around the perimeter and up the centre as recommended by structural engineer (where timber frame panels will be).
I've started to lay my sub-base (803), next will be a layer of sand. After this i plan to construct my formwork around the perimeter, lay my DPM, place steel mesh and then pour concrete.
I think i'm doing this the correct way? Any advice would be gratefully received? Really want it to be right before the scary pour of concrete
Thanks in advance
