How do I know if my house slab is structurally sound?

A compliant house slab’s soundness is confirmed through the certification process itself — your engineer’s certified design, proper inspections during construction (reinforcement, formwork), and final compliance sign-off, not something you assess informally after the fact.

Once complete, genuine ongoing signs of soundness include the absence of significant new cracking, doors and windows continuing to operate properly, and no visible unevenness developing in floors over time.

If you have specific concerns about an existing slab’s condition, a professional structural assessment is the genuine way to get a real answer, rather than trying to judge it yourself from surface appearance alone.
