I have a piece of beach front land that is sand (sometimes wet), what kind of foundation do you pour for a home constructed on sand?
What kind of considerations do you take in if its water front and could get wet?
I cannot find any info on this at all, anywhere… so if anyone has an example codes page I'd also love to look at it so I can know what to ask for here.
Cheers
If it's not a huge pipe, hydraulic cement would probably do the trick. Hydraulic cement is designed to expand as it cures and is used for reparing foundation cracks.
Never use chicken wire or fiber glass meshing, they don't do anything.
When it comes to non rebar reinforcement you have some options. In your case I would add fibers. This type of reinforcement is called FRC or Fiber Reinforced Concrete.
Steel fibers add tensile strength and have no weak points like rebar does because they are spread throughout the slab. They also improve impact resistance and freeze-thaw damage.
On the other hand you can also add polypropylene and Nylon fibers, as they do a similar function. I'll add more on this if you need.

You don't construct houses on sand. Sand can't be compacted and, as such, will never be a solid piece of earth to place a foundation on top of.
Houses that are built on beaches are typically built upon concrete piers which go down to solid earth under the sand. Ideally bedrock.
As for what kind of foundation you need (or are even allowed to have) it will depend mostly on building codes in your area.
