What to do with side of my slab brick or render?

Hi Everyone,

I am building a new home, the slab is double podded so it is quite high (approximately 700mm) because of minimum height requirement for my finished floor level because of a flood overlay on my land.

My concreter was useless and the sides of my slab are in and out because the formwork blew out. I have concrete panels in a rebate and I am not sure how to repair the sides of my slab so they can match the level of my walls. In some places the slab is 10mm under my walls and in others it is 30mm outside.

I have considered getting a concrete saw and cutting grooves in the side of the slab and knocking away the excess until it is 10mm underneath my walls then rendering or cladding it somehow and bringing the side of my slab out about 3 or 4 inches from the levels of my walls and angling the top down to let any water drain away from my walls.

I have no idea what would be the cheapest or the best way to achieve my aims.

If there is anyone here that could offer me some advice on the best course of action I would greatly appreciate it.

Thanks,

Hi Koz... Is it possible for you to post a photo or two to show exactly what you're dealing with? Some of us are a bit thick... Or maybe it's just me.
