Crawl space is dirt. Foundation material; poured concrete. Floor construction: Joists. Exterior wall construction: wood frame. Roof and ceilling fraiming: Trusses. 80% of the foundation was not visible at time of inspection. There is a moisture barrier in the crawl space there but it only covers about 90% of the ground and needs to be extended to the foundation walls. The lot slopes away from the house and there is eave mounted gutters and downspouts pointing away from the house. One of them is broken and pointed beside the house so that needs to be extended a couple feet. There were a couple small cracks in the foundation but he saw them as little concern and simply to fill/seal. That's all of the info for the foundation. I hope the reposted pictures help. By the sounds of it, the sill plate was underground originally, it started to rot out, so they replaced it and elevated it just above ground. Elevation was done poorly (obviously not U2), so there are not gaps there.
