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 Surfside Beach 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 Surfside Beach 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 Surfside Beach. Homes near Floral Lake in particular tend to need the drainage question answered as well, or the space simply returns to how it was.

Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Surfside Beach floor for a year has already changed what the repair involves.

Vapor barrier in Surfside Beach: common questions
Barrier or full encapsulation for a Surfside Beach home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Horry 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 Floral Lake, drainage comes first or the sheeting simply floats on it.
Does being close to the coast make this worse?
It raises the water table and lengthens the wet season, which is why homes near Floral Lake and the low ground around Surfside Beach tend to need drainage as well as a barrier.
My house is near Floral Lake. Does that change anything?
It can. Being close to Floral 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.
Why is my Surfside Beach crawl space wet when nothing has leaked?
Near Surfside Beach 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.
Should the crawl space vents be closed?
It depends on your climate. In humid regions, open vents often bring in air that is wetter than the crawl space, which deposits moisture on cool surfaces instead of removing it — so sealing vents and controlling humidity mechanically usually performs better. In drier climates venting can work. This should follow readings, not a rule.
