We will tell you if crawl Space Vapor Barrier Installation is not what your Ravenel crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on lowcountry and coastal plain ground
A barrier earns its keep faster around Ravenel than almost anywhere. With the water table close to the surface the soil underneath is damp more or less permanently, so an uncovered crawl space floor is evaporating into the space every day of the year.
In Ravenel the complication is the water table. It sits close enough to the surface that soil under a house can be saturated with nothing broken, so this work is usually dealing with moisture arriving from below rather than from a failure inside the house.

What the work involves
What we do on a Ravenel job of this kind:
- Clearing and preparation of the crawl space floor
- Reinforced polyethylene barrier across the full soil area
- Overlapped and sealed seams
- Barrier carried up and sealed to walls and piers
Why it is worth dealing with now
Nothing about a damp Ravenel crawl space improves on its own. The space is enclosed, shaded and over soil — all three work against it drying out.
The full method and the step-by-step for this work is on the Crawl Space Vapor Barrier Installation page, and how it behaves across the state is on the Vapor barrier in South Carolina page.
Vapor barrier in Ravenel: common questions
There is already plastic under my Ravenel house. Is that enough?
Often not. Most of what we find has been laid loose, has torn, or was never sealed at the seams and walls. Unsealed sheeting performs much closer to bare soil than to a finished barrier.
Barrier or full encapsulation for a Ravenel home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Charleston County property needs should follow a humidity reading, not a preference.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Ravenel property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Ravenel call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Do you work outside Ravenel itself?
Yes. We cover Charleston County broadly, including Hollywood, Meggett and Adams Run, and the rest of the Lowcountry and coastal plain of South Carolina.
Will a barrier fix water that is already coming in?
No. A barrier manages soil moisture and vapor, not liquid water under pressure. If groundwater or surface runoff is entering the space, that needs drainage and a sump before a barrier will do its job.
