A slab is checked once, in the hours before the pour. After that, the steel, the pipes and the barrier underneath are sealed in concrete for good.

On Berwick waffle slabs we keep recording the same group of items: steel too close to the form face, mesh touching service pipes, bar chairs missing and beams narrowed where pods were knocked out of place.

It is how much concrete sits between the reinforcement and the outer face of the slab. Too little and the steel can rust and burst the concrete over time.
A 25mm gap lets concrete fully surround both. Contact leaves a weak spot and a route for corrosion.
They hold the steel at the right height so it sits where the engineer placed it in the slab depth.
We look for collars and barriers at penetrations and whether the durable notice is in the meter box.
Yes, but most of what matters is then hidden. Pre-pour is the useful visit.
Same day in most cases, so the builder can act before the concrete arrives.
