Why it matters here

Bored piers inspections on Morayfield builds

Piers come into Morayfield builds where a footing has to reach past fill or soft ground to the material the engineer designed for, and some lots use screw piers instead. On the one Morayfield pier job in our records the screw piers were set out where the engineering showed them. The common failings elsewhere in the north are bases left full of loose spoil and holes still being drilled when the concrete was due.

What we find at this stage in Morayfield

  • Soil or builder materials remaining at the bottom of the excavation
  • Piers poured behind schedule
  • Short of the engineering drawings.
  • Morayfield building inspections
  • Inspect foundation details against drawings

FAQ

Bored piers inspections in Morayfield: common questions

How much time does a pier visit need on a Morayfield lot?

It takes about an hour for most blocks, and longer if the site has many piers or deep holes.

How are screw piers inspected?

We verify the location of each fixture against the installers log, rather than opening up the walls to look inside.

How do I clean the slab base?

Loose ground settles under house weight. Foundations must sit on stable ground, not loose fill.

Which papers should a Morayfield owner send first?

We check excavation depths and post positions against the engineering drawings and soil reports.

Are the piers completed?

We mark any incomplete works so the builder can fix them. A partial inspection leaves too much to guess work.

Do you issue certificates for the building work?

No. Principal Certifier Inspections Issue Certificates. We record all our findings for you.
