Should I add extra concrete for a raft foundation compared to isolated footings?
Raft foundations typically use significantly more concrete than isolated footings because they form a continuous slab across the entire building footprint rather than localised pads under individual columns. If your soil report has pushed your design toward a raft foundation, calculate its volume as its own large-area, uniform-thickness element rather than trying to adapt an […]
