Profile: Nova Basement Systems is a crawl space repair, waterproofing and foundation repair contractor. Our foundation helical anchors include a long rod and a cork screw-like helical shaft that mounts to the wall plate on the inside of the foundation walls. The helical anchors are installed and anchored into the soil. Once the helical anchor is in place, the hole is refilled with concrete and a wall plate is installed over the top. Our sump pump system includes airtight sump lids, clean pump stands, sump liners, and water watch alarms. Airtight sump lid keeps odor & humidity out, and protects the sump from debris. We also offer vapor barrier systems, dehumidifiers, and wall anchor systems.
