when pouring concrete slab should you pour the walls first then the flour or should the foundation be poured first then the walls any?

walls 1st then floor

depends it can be done both ways

foundation/footer first, then walls, then floor.

foundation first.

if you have any sense you will do the footing and the floor as one ..here in uk we call it a raft ..then you have a clean area to work on to construct walls

We built our own septic tank that way! Walls first, then the floor! After the floor, we then built the separator wall in the center.

Walls and piers first, then the floor.

It depends on local requirements, of course. You can pour footers, slab and stem walls all in one pour in a few staggered lifts with sufficient delay from one to the next to prevent the weight of subsequent lifts blowing out the earlier ones. What I've done is pour footers and stems, then come back and pour the slab inside that and follow up with block on top of the stem walls.

Slabs don't have walls. They are just... slabs.

If you are talking about the footings, pour everything at once.

If you are going to pour concrete for a house. I would hire someone that knows what they are doing.

They are so many building codes, you all so have to know.

You should pour your slab first for your foundation, then your floor, but there is a lot more to it.
