My question is ,the land I'm looking to build on ,is a water front property,and is still treed.But the land soil,is damp and mossy,what is the best way to build.Do I need to put sand ,stone .Or is there other forms,to prevent dampness,in the foundation.
Most often with land that is soft/damp etc. you need to pre-load it and wait until soil testing determines it is a the correct density to support a structure. Check with your local building department for more information. Hope this helps.
You may also want to look at any other possible causes of wetness like lot sloping, elevation and drainage. It's not uncommon to require grading or clay fill to mitigate future wet conditions.
Of course if it's simply caused by the proximity to water and porous soil, then your foundation type will be critical. Consult a foundation expert and get a soil profile/analysis for this from someone whose experience you can verify and avoid potential pain.
Piles and concrete grade beams are a good idea but have a geotechnical engineer to confirm the psi ratings for your piles into hard pan and then have a structural engineer design your reinforcement and your concrete. This is the system I am currently using on a project.
