Most Sardinia homeowners arrive at crawl Space Vapor Barrier Installation having noticed something else first: a smell, a soft patch in the floor, or insulation on the ground. The inspection decides whether this is the right stage to start at.
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 Sardinia 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.
Coastal Clarendon County humidity is the other half of it. For much of the year the outside air here is wetter than the crawl space, so any approach that relies on ventilation to finish the job works against itself.

Why it is worth dealing with now
The gap between a drying job and a structural repair in Sardinia is usually measured in seasons, not years.

Vapor barrier in Sardinia: 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 Rainbow Lake, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a Sardinia home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Clarendon County property needs should follow a humidity reading, not a preference.
Does storm flooding reach crawl spaces around Sardinia?
Yes, and often with nothing visibly broken. After a tropical system the usual picture in Clarendon County is a saturated crawl space where the water came up through the ground rather than out of a pipe.
Why is my Sardinia crawl space wet when nothing has leaked?
Near Sardinia that is the normal pattern rather than the exception. At around 102 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
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 Sardinia property changes that.
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.
