slightly off topic, but would the epoxy be flexible enough to cover the fine cracks, if say it was applied straight after house handover and the house was still settling?

Have you ever seen anyone build up soil against the slab and compacted it ? even though the regulations say it should be graded away and how to you compact soil on an angle? The reality is no one does it or very rarely does any builder comply with AS2870 as far as drainage goes. You can go to any new estate and see drainage isn't done. It usually is built up with gravels, rubble, tan bark which makes the drainage situation worse than simply not comply with drainage requirements.

Our private inspector noted that it's not graded properly in our report. I was speaking to another SS from another company and he said they are supposed to do it but most don't. I feel that due to it being specified in soil report and drawings that site would be difficult in wetter months, they would follow drainage. Site was first cut in July (winter).

But you are right I have only seen one site graded away during excavation earthworks and only one after the slab was poured both times not that good but at least the builder made an effort.

No virtually no builder does it's standard practise not to do it and builders don't realise it leaves them legal vulnerable. Thats why photos are very important. Like noname said get an engineer to investigate it may not be a problem. Re: Slab cracks 39Jan 12, 2023 6:12 pm My drawings state with a site cut must have shallow agricultural drain or (swale drain) at base of the cut directly onto natural material. Then states refer to AS2870-2011 section 5.6.1, 5.6.2 and 5.6.3 and soil report. I think I got confused earlier with grading and drainage from site cute.

Have i seen it? yes. my builder does this to literally every house they build. You compact it with the excavator.
