The owners were tax evaders and bribers. Truth had no place in their vocabulary. They are dead and gone, current owners have to cope with this shitstorm A concrete slab, with water penetrated rebar will progressively fail in an exponential manner because rebar oxidizes = irrestible expansion and progressive expansion of the corroded area. Concrete and steel in these situations turn to dust and gravel with zero residual strength. If the other building has a pool in the same relative position it needs inspection ASAP. If no pool, they may be OK as that mechanism of failure would be absent. That said, the owners were such scumbags that other structural shortcuts may be hidden and will need to be dealt with
