Subgrades & Subbases for Concrete Slabs

 · The subgrade soil can also be excavated and mixed with gravel then compacted. For some difficult soils, the subbase may be placed atop a layer of geogrid. 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.
