Cracks in a concrete slab, or in tile and grout, can be cosmetic, or they can be the floor reacting to a foundation that has moved.

What Soil Is Sumter Built On?
The USDA sample inside Sumter is mostly Johnston soil, a deep gray fine sandy loam. In a USDA sample of five points inside Sumter, three are Johnston, one is Wagram and one is Rains. The wider county survey for Sumter County leads with Rains, at about a tenth of the land, then Norfolk, Lynchburg and Noboco. The USDA rates the sample inside Sumter low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
Johnston is a deep soil that formed from sediment laid down by streams, usually found on stream flood plains. Its top layer is dark, organic loam, and under that is gray fine sandy loam. Loam is soil with a mix of sand, silt and clay. It holds water at or near the surface for much of the year.
Wagram is a deep soil that formed from old marine and river deposits of the Coastal Plain, usually found on Coastal Plain uplands. It is sandy for about the top two feet, and under that is yellowish brown sandy clay loam. It drains quickly.
What It Means for Your Home
- FoundationsSoil that stays wet can stay soft under a footing, and water moving through sand can carry soil out from under it. Look for uneven floors and a settling foundation. See foundation repair.
- Crawl spacesWater close to the surface can mean standing water and damp air in a crawl space for much of the year. Look for moisture in the crawl space and sagging floors. See crawl space repair and crawl space encapsulation.
- Floor framingWater close to the surface keeps the air under a house humid, and joists and beams that stay damp can rot and weaken. Look for rotted floor joists, and broken or cracked joists. See framing repair.
- ConcreteSlabs on ground that stays wet can settle unevenly, and water running under a slab can wash sand out from beneath it. Look for broken or sunken sidewalks, and a cracked driveway. See concrete leveling.
Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov. Inside Sumter, the survey maps Johnston, Wagram and Rains series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 1.5 percent). Across Sumter County, it maps Rains, Norfolk, Lynchburg and Noboco series. Series descriptions: USDA NRCS Official Series Descriptions for Johnston and Wagram.
