BUILDING IN LOUISVILLE: WHAT TO EXPECT
Soil & Slab Notes — Jefferson County
Louisville Metro (Jefferson County) soils include Muskingum and Eden series — heavy, moderately expansive clay-loam soils derived from shale and limestone parent material. These soils have moderate plasticity and require a well-prepared sub-base and properly reinforced slab. Budget for a 5" minimum slab with a thickened perimeter beam extending below the seasonal moisture change depth. Sites near the Ohio River bottomlands carry higher groundwater risk; check FEMA flood zone mapping before selecting your parcel.
