What the Ground Looks Like in Hanahan
The soil survey, sampled at 61 points inside Hanahan, shows open water at 9 of them. The other 52 are natural soil.
At 18 of the 52, the shallowest yearly water table is at the surface, and 24 are within 30 centimeters. Nineteen are poorly or very poorly drained. Eight carry a very frequent flood rating.
Forty-one points have low shrink-swell, and three are moderate. Eight rate high: five Capers and three Bohicket soils. All eight are very poorly drained and very frequently flooded, with water at the surface.
Away from those spots, the survey points to water more than to swelling clay. See your own lot on the Web Soil Survey.
For wet yards, read about drainage and water control. For damp crawl spaces, see encapsulation and vapor barriers.

Hanahan Neighborhoods
Census numbers from the American Community Survey (2020 to 2024 five-year estimates) put the middle build year in Hanahan at 1986. About 53 in 100 of the roughly 8,700 homes were built before 1990. About 15 in 100 are from 2010 or later.
About 68 in 100 households own their home. About 71 in 100 homes are single-family houses, and about 5 in 100 are mobile homes.
The Census gives no foundation type. These are estimates, and the margin of error on the build year is wider here than in bigger places.

Our 5-Step Process in Hanahan
- Share the details. Give us your address, the age of the house if you know it, and what you see.
- Walk the exterior. The visit checks downspouts, grading and any standing water around the house.
- Test the older parts. Footings, piers and walls are checked for settling, cracks and moisture.
- Pick a repair plan. The contractor lays out the choices in writing. Ask what each one is meant to fix.
- Wrap up. You review the finished work together. If a permit applies, the office that covers your address handles it.

Foundation Questions in Hanahan, SC
Are older Hanahan homes more at risk?
Age alone does not decide it. About half of Hanahan homes were built before 1990 by Census estimates, and wet ground shows up often in the soil survey. Together they are worth an inspection.
How do I schedule an inspection in Hanahan?
The city page says to use the GovPossible portal or call (843) 576-5259 before 3 in the afternoon for next-business-day scheduling. It also says the head contractor requests inspections, so ask your contractor about timing.
What does a very frequent flood rating mean?
It is a flood rating in the soil survey for the mapped soil. Eight sampled points in Hanahan carry it. It describes the soil on the map, not your house.
