Why is crawl space drainage needed so often in Indianapolis?
Many Indianapolis homes built since the 1970s have crawl spaces on flat lots with clay soils, where water ponds after heavy rain. Crawl space drainage collects that water and sends it to a sump.
How is crawl space drainage done in Indianapolis homes?
Grading and downspout fixes outside reduce how much water reaches the crawl space in the first place.
What should Indianapolis homeowners know before booking water in a crawl space work?
A typical Indianapolis crawl space drain is a perforated pipe trench around the inside perimeter, sloped to a sump at the lowest corner. A heavy vapor barrier is then laid over the soil and up the walls so remaining ground moisture stays out of the air.
Warning signs, the full process and cost drivers are in the crawl space drainage guide.
