Re: concrete slab has some honeycomb3

Welcome to the forum
The defect is called Concrete Honeycombing
Was the Concrete inspected during the actual pour, do you have photos?
Are there other spots visible? More info required
It's always a good idea as an owner OB builder to understand your engineering Drawings/Details and Notes. Always inspect structural components, Take photos, keep records,ask questions, etc. Make sure you aren't taken advantage of by being an OB novice
I would recommend that you check all Building Tolerances from here on as well

Thanks everyone. The building surveyor inspected the slab before pour. The concretors used a concrete vibrator to ensure a compact slab and they also used a laser to ensure the slab was level. The concrete honeycomb was below the rebates which is probably why they missed it.
The next building inspection will be when the walls and roof are put up. I can ask the building inspector to make a point to inspect the concrete honeycomb then.
