Local conditions
Why is crawl space drainage needed so often in Greenville?
Greenville's red clay sheds water at the surface, and on poorly graded lots that water ends up in crawl spaces. Crawl space drainage collects it in a perimeter trench and pumps it out through a sump.
How is crawl space drainage done in Greenville homes?
Contractors also correct grading and downspouts outside, since clay soils hold water near the foundation long after rain stops.
What should Greenville homeowners know before booking water in a crawl space work?
Once water is controlled, a vapor barrier or full encapsulation keeps humidity down and protects framing.
Warning signs, the full process and cost drivers are in the crawl space drainage guide.
