    Subgrades amp Subbases for Concrete Slabs The Concrete

    Sand that you can drive a 4 rebar into about 1 foot with a 5-pound hammer has a bearing capacity over 2000 psf Also, remember that its not just the soil the subgrade that needs to be compacted. Any subbases or base courses, which will typically be granular materials, also need to be well compacted in the proper lift thicknesses.
