What Problems Do We Fix in Oak Island?
Floor Cracks
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 this looks likeSagging Floors
In most Carolinas homes, the cause of a floor that sags or feels bouncy is wood rot or weakened joists in a damp crawl space underneath.
What this looks likeCracked Driveway
Some driveway cracks are ordinary curing. Others are the slab reacting to soil that has shifted, washed out, or been heaved by a tree root.

What Soil Is Oak Island Built On?
The most common soil in the USDA sample inside Oak Island is Murville, a sandy soil. In a USDA sample of five points inside Oak Island, two are Murville, one is Leon, one is Kureb and one is Mandarin. The wider county survey for Brunswick County leads with Baymeade, at about a tenth of the land, then Torhunta, Leon and Murville. The USDA rates the sample inside Oak Island low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
Murville is a soil that formed from old marine and river deposits of the Coastal Plain. It is fine sand from the top layer down. It holds water at or near the surface for much of the year.
Leon is a deep soil that formed from old marine deposits of the Coastal Plain, usually found on low, flat ground. It is sand from the top layer down. It drains poorly to very poorly, and it can hold water at or near the surface for much of the year.
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 sagging floor joists and rotted floor 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 Oak Island, the survey maps Murville, Leon and Kureb series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 1.5 percent). Across Brunswick County, it maps Baymeade, Torhunta, Leon and Murville series. Series descriptions: USDA NRCS Official Series Descriptions for Murville and Leon.
