Why it matters here

Bored piers inspections on Riverstone builds

Piers turn up on Riverstone lots where the footing must reach through fill or soft alluvial ground, and on land near the creek lines that flooded in 2021 that is not unusual. Depth is the whole exercise and concrete ends any chance of confirming it. Every photograph on this page was taken at practical completion, not at this stage. They are here because each one is an item that belongs earlier in the build and survived to handover, which is the clearest argument we can make for inspecting when the work is still open.

What we find at this stage in Riverstone

  • Bore shallower than the engineering requires
  • Cage off centre, leaving uneven cover
  • Water or spoil sitting in the base
  • Cage lifted clear of the bottom
  • Reinforcement unsupported ahead of the pour

FAQ

Bored piers inspections in Riverstone: common questions

How long does it take?

Under an hour on a typical lot, longer where the pier count is high.

And if a bore is shallow?

The measured depth goes in beside the required depth, and the remedy belongs to the builder and their engineer.

Do you certify footings?

No. We record against the engineering; certification is an engineer's function.

Does water in the bore matter?

It weakens the concrete at the base, so recording it means it is pumped out before the pour.

Is the flood history relevant here?

Indirectly. Ground conditions on land that inundates tend to be why an engineer specifies piers in the first place.

What should I send?

Your lot engineering with pier depths, diameters and positions.
