Why it matters here

Bored piers inspections on Clyde North builds

Not every Clyde North house sits on piers, but the ones that do are usually lots where the engineer wanted the footings to reach past fill, a service trench or softer ground. That makes the hole itself the thing that matters, and it exists for a few hours. We have seen piers drilled off the beam line and pier holes already filled with concrete when the inspector arrived, which leaves nothing to check.

What we find at this stage in Clyde North

Pier holes drilled off the line of the beam above
Loose spoil left at the base of the hole
Concrete poured before the inspection could happen
Depth not matching the engineering
Cages without proper cover to the sides

FAQ

Bored piers inspections in Clyde North: common questions

Why does a pier have to line up with the beam?

The pier carries the beam's load straight down. Offset from the beam, it puts that load where the slab was not designed to take it.

What is wrong with a bit of loose soil at the bottom?

The pier is meant to bear on firm ground. Loose spoil compresses under load, so the pier can settle even though it was dug to the right depth.

What if the concrete is already in?

Then the hole cannot be checked and the report says so. Ask the builder for the depth records and the engineer's or surveyor's sign-off for that stage.

How long is a pier hole inspection on site?

Usually under an hour, longer if there are many piers or the holes need measuring individually.

Which documents do you need?

The footing plan and the engineer's pier schedule, plus the soil report. Pier depth and diameter are judged against those.

Is a pier inspection worth booking on its own?

Where your engineering calls for piers, yes. It is the only time the founding of the house is visible.
