G’day. This is Matt Cornell from Cornell Engineers. This is a waffle slab inspection that we did a little while ago and I wanted to go through and put some words to it to let you know what we’re looking at during this inspection.
So here we go coming in from the front I’ll just pause it there and explain some of these things.
The white things that you can see are the polystyrene waffle pods. They are the voids in this soon to be poured concrete waffle slab. The waffle pods are about one-metre x one-metre squares. They’re sort of semi-hollow underneath. They’re not solid polystyrene but on top they’re solid. The space between waffle pods is about 110mm wide.
