I've never heard of a builder doing a construction joint in a waffle slab before. Definitely need your engineer to approve the two-pour slab in writing before you let them…

Hi ctvu
It is certainly more complicated and more susceptible to gapping.
Here's what I found online:

Perpend dispute with builder

This might help. It's an extract from the previous version of AS3700 regarding mortar joints but I doubt it changed in the most recent version. Bluff and say it's current!

Try these guys:

But that isn't a lot of money for an extension. You might be able to do a nice renovation though?

I'll take a bet both ways.
If the cavity is filled with mortar, I don't think brick ties will be required but I'd be concerned the steel could corrode unless you…

This wouldn't be the first time a polished concrete slab has had cracks in it. What did your contractor say?

soil teste at Warralily Coast

In theory it should rule out you using a waffle slab if your house is brick veneer. There is no off the shelf waffle slab design for H2 and H2-D.

Sounds funny. M-D is a soil classification in areas of deep seated movement - ie extremes in seasonal moisture. It has nothing to do with flood risk. Ask your soil…
