What crawl Space Vapor Barrier Installation involves in Meggett is the same as anywhere. What differs is the condition it is dealing with, and that is set by the ground the house sits on.
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 Meggett 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.
Low ground and a long wet season change what this work has to withstand around Meggett. Homes near the Wadmalaw River in particular tend to need the drainage question answered as well, or the space simply returns to how it was.

Vapor barrier in Meggett: common questions
Barrier or full encapsulation for a Meggett 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.
There is already plastic under my Meggett 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.
Does being close to the coast make this worse?
It raises the water table and lengthens the wet season, which is why homes near the Wadmalaw River and the low ground around Meggett tend to need drainage as well as a barrier.
My house is near the Wadmalaw River. Does that change anything?
It can. Being close to the Wadmalaw River 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.
Why is my Meggett crawl space wet when nothing has leaked?
Near Meggett that is the normal pattern rather than the exception. At around 10 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.
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.
