Hey gang,
Recently our builder slugged us with an extra $4k of site works. I've asked for a breakdown of the costs and one item was:
* Waffle slab upgrade to a Waffle type 4B with bored piers due to the amount of existing fill and placed fill on site - $13,795
Has anyone ever heard of a Waffle type 4B slab? Even Google isn't helping me out much with this one.
Cheers!
