    In realtion to slab foundations (there is no W):

    M = moderately reactive clay or silt sites - moderate ground movement from moisture changes

    P = soft soils, soft clay, loose sand, collapsing soils or areas subject to errosion, soils subject to abnormal moisture conditions, or sites which don't fit other classifications

    Not sure what they mean in relation to the actual slab though ?

    Thumbs up

    Happy to help. This is actually one I deal with from week to week.

    In realtion to P (problem sites), the slab & foundation must be engineer designed. For other classifications you follow the australian standards & building code.
