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

Why it is worth dealing with now

Vapor barrier in Martin: 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 Dead River Lake, drainage comes first or the sheeting simply floats on it.
Barrier or full encapsulation for a Martin home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Allendale County property needs should follow a humidity reading, not a preference.
Does storm flooding reach crawl spaces around Martin?
Yes, and often with nothing visibly broken. After a tropical system the usual picture in Allendale County is a saturated crawl space where the water came up through the ground rather than out of a pipe.
Why is my Martin crawl space wet when nothing has leaked?
Near Martin that is the normal pattern rather than the exception. At around 92 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 Martin property changes that.
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.
