Browse Forums Building A New House 1 Jun 27, 2014 11:43 pm Hi all We are currently looking at building a place in Bedfordale. We recently got back siteworks and lets just say i need to consider other options. Putting aside that in WA the norm is Double brick concrete slab homes, I am considering a steel stud frame build that would be elevated on poles/stilts. The question i have is this: rather than a wood floor on the stilts are there other options for a concrete floor. Something along the lines of how the second story was done on the place next to our current house. In their case they had a trestle style floor structure, with a tin layer and then maybe a 50mm or so concrete slab. Can this be used on stilts? thanks Re: Flooring for pole/stilt based home 2Jun 28, 2014 1:29 pm Possibly, but you would need to speak to a structural engineer regarding the design and what is possible. They would more likely have to be concrete reinforced columns. If you are doing this for thermal mass there are other cheaper options too. Just be aware that to support a suspended concrete slab you also need pretty substantial framing underneath like piers and walls to carry the weight. I also doubt very much that it is only 50mm thick, more like 150mm thick just by nature of concrete slabs, reinforcing and the cover needed.

Can this be used on stilts? This sounds like Bondek or similar. The overall thickness of the slab is at least 100 mm but could be 125 or 150mm depending on the spans. There is typically 50mm concrete cover over the top of the Bondek ribs. Bondek is only strong in one direction so typically the Bondek panels need continuous support in the weak direction. This support could either be load bearing masonry walls or steel beams. The steel beams could be supported on substantial steel columns. The suspended floor and its supporting structure, and bracing needs to be designed by a structural engineer. Your neighbours floor is an internal floor so corrosion protection to the underside of the exposed steel Bondek is not an issue. However if your proposed suspended floor is exposed to the elements then corrosion protection to the Bondek panels may be required. Your structural engineer should be able to advise on this. Note the NCC/BCA requires external suspended floors below living areas to be insulated.
