I’ve been asked my opinion on a pier foundation support of a small house/camp comprised of block on top of stone that is 2 feet deep into the soil and the stone rests on bedrock - the soil content is unknown, but I assume it is stable - no apparent movement even with recent heavy rains - I have concerns of future soil compression/movement that can dislodge the stone and allow the block to move - there is no previous code inspection or construction information available - any comments or ideas

Hi to all,
Thomas, you are getting into an area that is way beyond the scope of a home inspector, you have stated that you see no signs of any current movement, if the buyer has concerns as to the future stabilityof the piers I would recommend that they engauge theservices of a licensed professional engineer.

Gerry - Yeah, I told the person that was outta my league and did suggest a structural engineer may be the person to consult - I was just curious as to what others might think about this application - Thanks Tom

I agree with others that you should just stick to what can be observed and reported. Stay away from opinions concerning capacity or stability. If you dont see any defects or indications of movement, just report that. Observe and Report … thats the job …
Are you sure that the stone (maybe "boulder") bears on bedrock? It does sound questionable, and I don't know why they wouldn't just simply place some sack mixed concrete or blocks down to bedrock.

I am absolutely amazed sometimes by how much thought goes into doing things wrong
