On a Ridgeland job, crawl Space Vapor Barrier Installation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
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 Ridgeland 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.
In Ridgeland the complication is the water table. It sits close enough to the surface that soil under a house can be saturated with nothing broken, so this work is usually dealing with moisture arriving from below rather than from a failure inside the house.

- Clearing and preparation of the crawl space floor
- Reinforced polyethylene barrier across the full soil area
- Overlapped and sealed seams
- Barrier carried up and sealed to walls and piers
Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Ridgeland floor for a year has already changed what the repair involves.

Vapor barrier in Ridgeland: common questions
There is already plastic under my Ridgeland 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.
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 Tismyr Lake, drainage comes first or the sheeting simply floats on it.
My house is near Tismyr Lake. Does that change anything?
It can. Being close to Tismyr 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.
Will my Ridgeland crawl space dry out if I open the vents?
Usually not. For much of the year the air around Ridgeland 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 Ridgeland 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.
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.
