Please comment below with your experience, your qualifications, and your recommendations.
- Do the provisions in AS2870-2011 as they relate to waffle slabs go far enough to protect Australians from uneven foundation movement?
- What is the major letdown in the system that is resulting in waffle slabs being overtly affected by slab heave in such large numbers?
- What can we do, as a profession, to improve the system and improve the performance of the Australian residential foundation systems?
- Are waffle slabs able to protect Australian homes from movement and damage?
- How do you account for large tie-down forces in cyclonic wind areas?
