The lazy concretor didn't vibrate the edges properly. And you don't have a vapour barrier. These are defects and should be rectified before the builder buries your slab in mud. They also need your builders engineer to sign off on the fixes. Get a licences building inspector. Re: Thoughts on this slab? 6Feb 12, 2019 9:35 pm The house is in WA. We do things differently over here and the slab is fine. No mud either. Just stable well draining sand.😉 Accessible Carpentry & Cabinets accessiblecarpentry@gmail.com accessiblecarpentry.com.au https://www.facebook.com/pages/Accessible-Carpentry-Cabinets/583314911709039 Re: Thoughts on this slab? 7Feb 13, 2019 8:39 am Resolute88 Check your Engineering Detail for Slab Step down I hope you took Photos before the concrete Placement Building Inspectors have no authority to check Structural Slabs & Elements In WA Most rely on the builders supervisor.. that's another story Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Thoughts on this slab? 8Feb 14, 2019 11:01 pm sweetswisssteel And you don't have a vapour barrier. Vapour barrier is completed either by the bricklayer by parging the slab edge or sprayed with a waterproof membrane, it should be done at least a week after the slab is poured Re: Thoughts on this slab? 9Feb 24, 2019 3:51 am Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I visited site again and noticed they installed a new PVC pipe, but they had to cut into the slab will do this (refer above photo). I believe they forgot about it and installed it in later. Will this weaken the concrete slab? I did a search of the forum and one of the posters in another thread suggested getting written confirmation from the engineer that this will not weaken the slab. Re: Thoughts on this slab? 10Feb 24, 2019 8:31 pm They need an engineered solution to do any works to the finished slab. So you have every right to request in writing the signed - off letter from their engineer on any of these works. Just get yourself an independent inspector and maybe hire a structural engineer too. Re: Thoughts on this slab? 11Feb 24, 2019 9:02 pm Hi, we had several cuts to fix plumbing mistakes in our waffle pod slab for our previous house. It was frustrating, and we had to force the builder to provide an engineering report....well they did it on their own accord once I went around taking lots of photos before they poured! Anyhow the good news is we had no issues at all with the house in 10 years living there, so you should be fine. My logic cutting into one section still leaves lots of strength in all the other beams etc. But I am certainly no expert, just going off our past experience. --------------------------------------------------------------------- Check our Homeone build blog here Re: Thoughts on this slab? 12Feb 24, 2019 11:38 pm That's my point, just make sure the engineer has signed off.
