Taken on its own, crawl Space Vapor Barrier Installation treats one part of the problem. Taken in order, it is the part that makes the rest hold. That is how we schedule it on Hardeeville jobs.
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 Hardeeville 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 Jasper 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 cost of this work does not stay flat. Every season a Hardeeville crawl space stays wet moves more of the job from drying towards framing repair.

Vapor barrier in Hardeeville: common questions
Barrier or full encapsulation for a Hardeeville home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Jasper County property needs should follow a humidity reading, not a preference.
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 Meyer Lake, drainage comes first or the sheeting simply floats on it.
Will my Hardeeville crawl space dry out if I open the vents?
Usually not. For much of the year the air around Hardeeville is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
How quickly does water under a Hardeeville house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Jasper County that window is shorter in summer than in winter, because the space stays warm and humid.
What should I have ready when I call about my Hardeeville home?
Your street in Hardeeville, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
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.
