What is CrawlDrain™ Crawl Space Drainage? 

CrawlDrain™ is a cutting-edge drainage solution tailored for crawl spaces. It features a 4-inch-thick corrugated and perforated pipe wrapped in a silt sock. 

In a crawl space, it is laid in precision-dug trenches and covered with gravel, serving as a filtration system to prevent clogging and guide groundwater to a sump pump. 

CrawlDrain™ is more than an individual product; it’s a crucial element of a broader home health solution. 

Combined with encapsulation, insulation, and dehumidification, CrawlDrain™ ensures your home’s structural integrity by managing moisture levels. Crawl space drainage installation is a wise investment for long-term home health.
