Why it matters here

Slab pre-pour inspections on Aintree builds

Our Aintree slab jobs have shown edge beams formed to the wrong depth, mesh laid directly on the ground, vapour barrier pulled tight over the steel and termite collars missing from the formwork. Each one is easy to fix now and impossible to fix after the pour.

What we find at this stage in Aintree

  • Edge beams formed at the wrong depth
  • Mesh resting on the ground instead of chairs
  • Vapour barrier draped over the steel
  • Termite collars not fitted to formwork
  • Insufficient seating for the shelter cover
  • Concrete recess not installed
Adjust the vapour barrier, recorded during a slab pre-pour inspection in Aintree
The vapour barrier was covered by the steel beams, which stops it from working properly
Deformed mesh, recorded during a slab pre-pour inspection in Aintree
The mesh was deformed which means the concrete cover might be compromised
Bar chair additional needed, recorded during a slab pre-pour inspection in Aintree
The inspector noted that additional bar chairs are needed to ensure the concrete cover allowance is met

FAQ

Slab pre-pour inspections in Aintree: common questions

What is the most serious slab finding you see in Aintree?

Wrong beam depth. One Aintree slab had an edge beam formed at the wrong depth because the formwork was not braced correctly.

Why does mesh on the ground matter?

The steel must be off the ground to protect it from corrosion and ensure correct cover. If it sits on dirt, the concrete cannot protect it.

Is the vapour barrier essential?

Yes. The membrane must be laid under the steel framing and taped to the joints to stop moisture.

Is the concrete pour on hold?

Fix before you buy. Our team checks concrete work on the spot so the builder can fix defects immediately.

What are the regulations?

A residential slab and footing specification, the engineer's design, and the soil report for your specific block.

Is a soil report required?

It helps. The concrete slab's rating determines how much steel is needed and the depth of the beams.
