Crawl Space Vapor Barrier for Griffin homeowners
Griffin clay does not drain, so water reaching the ground around a foundation stays there for a week or more. The perimeter of a crawl space here is damp far more of the year than the middle, which is why mold usually starts around the edges.
The crawl spaces are shallow, under mill-village homes and fifties ranches, with very little air movement. Damp ground plus still air is the combination that keeps humidity high, and a barrier is what removes the moisture source from that equation.
We grade the ground out, lay heavy reinforced material across the full footprint, tape every seam, and seal up to the piers and perimeter. On Spalding County clay we usually recommend pairing it with perimeter drainage, because sealing a space where water still collects at the edges only moves the problem along.
Our crawl space vapor barrier scope is the same on every Griffin home, whatever the Spalding County ground turns out to be doing.
- Puncture-resistant, overlapped seams
- Blocks soil moisture and humidity
- Protects joists and subfloor from rot
- A budget-friendly first step or full system
