Why it matters here

Slab pre-pour inspections on Wyndham Vale builds

On the reactive clay of the volcanic plain the slab is designed with stiffening beams for a reason. A beam poured narrow, or underlay that stops short, weakens exactly what that ground needs.

What we find at this stage in Wyndham Vale

  • Internal beam narrower than the engineering width
  • Waffle pods shifted out of their drawn positions
  • Underlay not continuous under the slab and beams
  • Penetrations through the underlay left untaped
  • Mesh sagging without enough support
  • Termite collars missing at plumbing penetrations

FAQ

Slab pre-pour inspections in Wyndham Vale: common questions

How late can I book a slab inspection?

A day ahead normally works, but tell us the pour date as soon as the builder gives it.

What happens when you find a problem?

The report goes to you that afternoon so you can pass it to the supervisor, and most items are fixed before the truck arrives.

Why does beam width matter so much?

Stiffening beams are what let a slab ride out clay movement. A beam half its designed width does not do that job.

Will the inspection hold up my pour?

The pour date is a matter for you and your builder to settle. Most slab items take a few hours to correct.

What standard is the slab checked against?

AS 2870 together with the engineering drawing for your lot.

Can the slab be checked after the pour?

Only the edges and surface. Everything inside it is out of sight for good.
