We will tell you if crawl Space Vapor Barrier Installation is not what your Bonneau 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 Bonneau 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.
Flood-zone construction around Bonneau is built elevated, which means newer homes have crawl spaces too. Newer framing, the same conditions underneath.

- 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 Bonneau crawl space improves on its own. The space is enclosed, shaded and over soil — all three work against it drying out.

Vapor barrier in Bonneau: common questions
Will a barrier stop water that is already getting in?
No. A barrier manages soil moisture and vapor, not liquid water under pressure. If water is entering the space near Gravel Hill Lake, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a Bonneau home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Berkeley County property needs should follow a humidity reading, not a preference.
Is crawl space water damage covered by insurance?
It depends on the cause, not the address. A burst pipe in a Bonneau home is commonly covered; groundwater, long-term seepage and flooding usually are not, and flood damage generally needs separate cover. Photograph everything first.
My house is near Gravel Hill Lake. Does that change anything?
It can. Being close to Gravel Hill Lake usually means a higher water table and a longer wet season under the floor, so drainage and a properly sealed barrier matter more here than they would further from it.
Will my Bonneau crawl space dry out if I open the vents?
Usually not. For much of the year the air around Bonneau is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
I already have plastic down there. Is that enough?
Often not. Most of the sheeting we find has been laid loose, has torn, has pulled away from the walls or was never sealed at the seams. Unsealed, incomplete sheeting lets ground moisture track around and through it, and performs much closer to bare soil than to a finished barrier.
