Stilts for home needed

[Hawai'i Is Home]

Galvanized steel strapping is one option, sold at HD in 25' rolls.

When you pour your footings, consider adding an ufer ground. Better than copper rods in lava rock.

Mahalo for your suggestions!

I would use something heavier than the strapping, either a long heavy tie plate (the ones hanging next to the rebar at HD) or some kind of post or column base, viz

Tie the lower part of the bracket to the rebar.

Some construction of exactly this sort just went up on Kilauea, across from/near the 76 station. Stack of hollow blocks, filled with concrete, big glue-lam beams across the top. The property slopes down, so the stilts put the apartments at eye level with the street.

Consider that large enough beams might require a crane or some kind of rigging.

Mahalo for the help : )

If you shoot for 9' columns, you could cut the 20' rebar sticks in half, giving you 10' lengths. Then when you pour the footing, and while the concrete is just starting to set up, simply stick the rebar straight down, 1' into the wet concrete, sticking up 9' out of the footings. After the footings set, put the sonotubes over the lengths of rebar. Use a little timber at the top of the sonotubes to hold the vertical rebar in position when you pour in the concrete for the columns. Simple.

Putting a slab on top makes it VERY difficult. This requires massive formwork to hold the slab in place at the top of the columns. This is for professionals only.

It MAY be possible to cast a slab on the ground and lift it into place afterwards, but I don't see the point in going through that. Put a shipping container or a wooden deck on top, much easier.

Thank you, I hope to put a small home with a lanai on top...I appreciate the input : )

Thank you everyone! Now to figure out just how many pillars would be needed for a 24x24 with a 12x24 covered lanai....
