Damaged slab =(

So after the other night seeing all the excavation works for plumbing at our block and all the mess, I went out the very next day to check it out but the plumbers had been backed and cleaned everything up, which was great to see. However I was able to get a good look at some damage made to our slab =(

UPDATE 30th November 2014

Was able to go onsite today and found even more damage to our slab!
