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 Gaston jobs.
Bare soil under the house is evaporating moisture into the space every day.
Vapor barrier on piedmont and upstate ground
On clay the ground under a Gaston house holds water long after rain, so the barrier is doing two jobs — stopping soil moisture coming up, and keeping the space off ground that stays wet for days at a time.
Clay also makes Gaston crawl spaces slow to dry. The surrounding ground gives moisture back reluctantly, which is why this stage is finished against a reading rather than a date.

Why it is worth dealing with now
A crawl space problem in Gaston is not self-limiting. The conditions that created it are still there, and they are still working.

Vapor barrier in Gaston: common questions
Barrier or full encapsulation for a Gaston home?
A barrier covers the ground and stops soil moisture. Encapsulation seals the walls and vents too and controls humidity directly. Which one your Lexington 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 Silver Lake, drainage comes first or the sheeting simply floats on it.
Why does my Gaston crawl space stay wet for days after the rain stops?
Piedmont clay. Around Gaston, at roughly 499 feet, the ground holds water against the foundation long after the surface looks dry.
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 Gaston property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Gaston call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
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.
