Can a raft slab be built in a single continuous pour?

Yes — a raft slab is genuinely designed to be poured continuously wherever practical, since the whole point of the raft is to act as one uniform structural element spreading load evenly across the site.

On a very large footprint, your contractor may need to pour in planned sections with proper construction joints, but that’s a deliberate engineering decision made in advance, not a default approach — your engineer specifies exactly where a joint is genuinely acceptable if one’s needed.
