Castleblock Building Material - Dennis - 10-08-2008
I am looking at different types of construction materials and the Castle Block product is very interesting. Can this material be used on a Post & Pier type construction? I am looking at building the entire house out of non-wood products. i.e. steel, castle block, trex etc.

Aloha Dennis,
I am currently working with Rob Tucker (and others) to build a house using ProTEC. I too wanted a structure built entirely of non-wood products. My plans have the house built on posts.

I am trying to understand the underside of the house. How is it sealed etc. The homes I have had built on the mainland all have foundations and basements.
Thanks

Dennis,
In post an pier construction, piers are placed in parallel rows, spaced every 6'-10' apart and 6'-8' on center. Posts and diagonal bracing extend up to girders which support the floor joists upon which is installed the plywood subfloor, generally glued and nailed to the floor joists. This creates a seal. The crawl space below is vented or open for outside air to circulate freely. Some choose to insulate under the subfloor, but not really needed in Hawaii's climate.

So how does the flooring described by Dan get translated in a fully "non-wood" house?
RE: Castleblock Building Material - Rob Tucker - 10-09-2008
My company, Castleblock, would employ a different floor framing system than the one described above.
We use light gage steel floor joists and posts and beams. Over this we have a substitute for plywood which is a structural cement panel 3/4" thick and 4'x8'T&G. The panel is non-combustible, termite proof and tile can be applied directly to it.
The layout of posts and girders depends on the house design and gage and size of the floor joists involved.
We make no structural use of wood. Wood is sometimes useful for forming concrete, bracing and pallets though.

I see that I was not paying attention to the thread. My decription was for conventional stick-frame construction.

We built a slab foundation house with Rob's ProTec SIP (structural insulating panel) for the walls (cement board sandwiching foam), including several interior walls, and a SIP metal roof (sheet metal sandwiching foam). And a lot of substantial help and advice from Rob for which we are still very grateful. The walls are attached to the slab by galvalume C-channels and the channels to the slab with foundation bolts and a thin insulating layer next to the concrete. The posts and beams are all galvanized steel. We felt the slab construction was simpler and appropriate for the materials. Our goal was to provide nothing for the termites (well, the doors were an exception) and building a non-tasty post and pier foundation seemed much more complicated for we owner-builders. Probably not so intimidating for someone actually well experienced in construction.

A friend of ours and also Castleblock client did a slab on post and pier poured in a galvanized pan, ProTec walls and metal sip roof. Rob might have some of the details.
While I did do ProTec on slabs, I used wooden column and beams to support the roof sips. I'm not that good a welder and as I get older takes me longer to learn. I'm happy with my hybrid approach and hope it outlives me.

"We use light gage steel floor joists and posts and beams. Over this we have a substitute for plywood which is a structural cement panel 3/4" thick and 4'x8'T&G. The panel is non-combustible, termite proof and tile can be applied directly to it".
I was wondering if there are photos available of the steel floor joists, and the posts and beams for an elevated house, say 3 or 4 feet? Perhaps a finished project that is not slab foundation.
Thanks,
