Hi all ,
Just wondering how thick an H class slab is. I've googled and can't seem to find the info.
The reason I ask is that our builder has 'found rock in all 3 bore holes' at 700mm depth (even though where we're building there are very few rocks according to many people!?!?)
Does anyone know whether they would have to dig this deep to lay our H Class Slab?
Many Thanks
TC
