Re: Has anyone rectified slab heave successfully 939Oct 20, 2019 10:40 am SaveH2O I have often wondered what would happen in the scenario where a builder didn't attend to site drainage (some are recidivists) and the new home owner had site moisture samples taken pre handover and the site was found to have high moisture levels in different areas next to the slab. Could that alter the site classification, arguably making a standard waffle slab under-engineered and thereby non compliant? A bit like buying a new car but driving away with retreads perhaps? Yes I can confirm this happens. For example if you have a class H2 site classification and the builder doesn't address site drainage during construction then the soil moisture levels can rise and the site becomes a class P(abnormal moisture conditions).If this happens then ground movement can exceed the designed ground movement for the slab and hence slab heave. The builder will usually say well this happened after hand over. Re: Has anyone rectified slab heave successfully 940Oct 20, 2019 2:38 pm insider Yes I can confirm this happens.

It also appears that some builders give scant attention to site drainage when a raft slab with piers is used. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.
