Does a house slab need different treatment on a bushfire-prone site?

Yes — a property’s Bushfire Attack Level (BAL) rating genuinely influences construction requirements, and while the slab itself is non-combustible, edge detailing and any subfloor considerations are assessed against your specific BAL rating.

Your building surveyor confirms your site’s BAL rating early, since it’s a genuine, binding input into your overall construction approach, not just the slab.
