Hey there, On a job, and the client has water coming through up a thin concrete slab foundation (2inch) near wall. The rest of the concrete slab is about 15cm thick and is dry. Don't think we need to have DCP'ing, just think we need to build up the thickness of the concrete slab foundation where it is thinnest. and add more ventilation. The property is built on clay and is mid 1930's. What do you think is the best course of action?
