Why it matters here

Slab pre-pour inspections on Gledswood Hills builds

The slab carries everything above it and its engineering lives in beam geometry, reinforcement and cover, none of which can be seen once concrete is placed. On the Oran Park job behind these photographs the vapour barrier was recorded with sections missing, which is the clearest possible example of a pre-pour item: trivial to fix on the day, impossible to reach afterwards.

What we find at this stage in Gledswood Hills

  • Vapour barrier not continuous beneath the slab
  • Cover to reinforcement below the minimum
  • Beam geometry not matching the engineering
  • Service penetrations set out incorrectly
  • Recesses and set downs not formed

FAQ

Slab pre-pour inspections in Gledswood Hills: common questions

What does the vapour barrier do?

It stops ground moisture rising into the slab and the floor above it. A section missing is a hole in a barrier that was specified as continuous, and it is under concrete an hour later.

Can anything be checked after the pour?

Only the surface. Cover, steel, beam sizes and the barrier all stop being verifiable the moment the concrete goes down.

What if the pour is moved?

We move with it and there is no charge for the change.

How long is the visit?

An hour to ninety minutes on a standard lot, with the report out that evening because the pour is the next morning.

Do you check penetrations?

Yes. Moving a waste before the pour takes minutes; moving it afterwards means cutting the slab.

What should I provide?

Your lot engineering, and the soil report it was drawn from.
