Slab damage Picture

Hi Gurus,
I am seeking some advice on the extent of damage to the Slab in the Picture here. What is that metal piece visible through the Void. Any feedback will be much appreciated. This is one of the Corners in the Slab.

It looks to be a piece of the steel reinforcing that has been exposed. The slab design will specify a minimum amount of concrete cover over the steel reinforcing (typically 40 to 50mm). You should request that the structural engineer associated with the slab design certify any rectification works.

We had a similar experience when a lower layer of reinforcing steel shifted down during the slab pour... viewtopic.php?p=1877733#p1877733

No one seemed to notice it except for us. Not the builder, the engineer or the concrete contractor.... in fact no one seemed to even look, they just stripped the form work and moved on. So we raised it as a defect and the concrete contractor sealed it, but who knows what method/materials they used.

We have relisted it as a defect until the structural engineer certifies the rectification works.

Hey nfaisal Welcome to the forum
You will require your own engineer to check the slab
Pity you didn't have it inspected and photos taken prior and during the footing/slab pour here
Non Compliant Concrete Footings/Slabs
Proof is required should the dispute escalate further down the track also put all complaints to the builder in writing/email
Cheers
Chris

Thnx Mate. Interesting enough that it wasn't there post Slab pour. Someone messed it up afterward while scrapping don the extra Mortar from the base joints. I have take this up with SS and he acknowledged it. I have asked for an Engineers's report on this before and after they fix it. Let's see how it goes.
