BUILDING IN SAVANNAH: WHAT TO EXPECT
Soil & Slab Notes — Andrew County
Andrew County soils are primarily Grundy and Shelby silty clay loams on the gently rolling uplands — deep loess deposits with good structure and moderate bearing capacity. These soils swell slightly when wet and crack when dry, so a 5" reinforced slab with a thickened perimeter beam and compacted gravel sub-base is standard practice. Savannah sits on upland terrain above the Missouri River floodplain; most rural parcels in Andrew County are well-drained and well-suited for a straightforward slab-on-grade foundation. Frost depth for Andrew County is approximately 26 inches — deeper than much of Missouri due to north-country exposure.
