Soil compaction is the act of squeezing out as much air and moisture as possible to push the solid soil particles together—this makes the soil more dense and typically the higher the soil's density, the higher its bearing capacity. Well-compacted soils also do not allow moisture to move in and out as easily. See more The terminology used for soil support systems, unfortunately, is not completely consistent, so let's follow the American Concrete Institute's … See more The weight of the slab and anything on top of it is going to eventually be supported by the soil.
