Moisture is very important in the compaction of the soil. Too much moisture and the soil will not compact, not enough moisture and the soil will not compact to the necessary levels. Soils with primarily fine particles will not compact enough to bare the weight of a foundation, they tend to just displace into another area. Soils suitable for bearing the weight of a foundation need the right proportions of large particles (rock) and fine particles, this will allow them to interlock with each other and form a bond. I watched one project south of where I live go on for months before the first form was set for concrete. They excavated the soil, down about twenty-five feet and removed it from the site and replaced it. It was for two story townhomes and the foundation was probably about fifteen thousand square feet. That is a lot of soil to remove and replace, I kept thinking there has to be a better more cost-effective way.
