Concrete Slab and Wood Piles
Concrete Slab and Wood Piles
(OP)
I am designing a 3-story beach house. My question is the second and third story are being supported by piles that are embedded more than 20' deep in sand. The first floor garage will consist of reinforced concrete slab on grade foundation. Question: what type of material could be used between the wood piles and the concrete slab to allow for expansion or contraction?

Even the thinest of theses materials (1/4" for the link above) should be sufficient. Often the concrete slabs are cast directly in contact with timber piling that pass thru the slab - with no problems. But a little "wiggle room" is better, IMHO.

The concrete is going to crack, so reinforce it to control them. I am not even sure if you would prevent any additional cracks anyway by providing a gap. I think the added stiffness you will give the building is more important anyway. A lot of beach houses I have been in will make you sea sick if there is a stiff wind.
