Groundwater was a problem for this Stratford, CT basement. It was seeping into the crawlspace and causing problems with humidity and mold. The SmartSump system provides excellent protection from groundwater leaks, and has the added benefits of a cast-iron Zoeller sump pump, a reliable liner, a sump alarm, and an optional battery backup sump pump. It's exactly what this crawl space needed to ensure a dry space all the time!
