The ground in Wilmington
How Does Wilmington Soil Affect Basements?
The most common soil in the USDA sample inside Wilmington is Seagate, a deep sandy soil over light gray clay loam. The USDA sampled five points inside Wilmington: two are Seagate, one is Leon, one is Baymeade and one is Lynn Haven. The wider county survey for New Hanover County leads with Murville, at more than a tenth of the land, then Leon, Kureb and Bohicket. The USDA rates the sample inside Wilmington low for swelling and shrinking.
Seagate is a deep soil that formed from old marine deposits of the Coastal Plain, usually found on Coastal Plain terraces. It is sandy for about the top three feet, and under that is light gray clay loam. Loam is soil with a mix of sand, silt and clay. It drains somewhat slowly, and it can stay wet near the surface for part of the year. The USDA rates it low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
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.
Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov. Inside Wilmington, the survey maps Seagate, Leon and Baymeade series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 2.7 percent). Across New Hanover County, it maps Murville, Leon, Kureb and Bohicket series. Series descriptions: USDA NRCS Official Series Descriptions for Seagate and Leon.
Our approach
How Do We Approach Basement Waterproofing in Wilmington?
A wet basement in Wilmington almost always traces back to water pressure in the ground around the home. That pressure, called hydrostatic pressure, pushes moisture through tiny cracks, through porous block, and up through the seam where the wall meets the slab.
We start every project with an inspection to find where the water is actually entering, then explain what we see in plain terms before recommending anything.
Depending on the cause, the answer may be an interior drainage and sump system that manages water that reaches the wall, a basement vapor barrier that stops ground humidity, targeted crack repair that seals a specific leak, or a combination.
If the issue is simple humidity with no active water intrusion, we will tell you that too. The goal is a basement you can use, diagnosed and matched to the right system.
Warranty terms, with their conditions, are on our warranties page.

They were on time, provided excellent customer service and took time to answer all my questions. They delivered exactly as promised in the initial inspection and contract. I highly recommend them and would definitely use them in the future.
