Lac Du Flambeau, WI's Dependable Contractor for Basement Waterproofing & Foundation Repair

During inspection, we measured settlement across the garage apron and front walk, identifying voids beneath multiple panels from years of drainage runoff and frost movement. The crew drilled small ⅜-inch injection ports and injected PolyLevel® polyurethane foam to fill the voids and gradually lift the slabs to their original elevation.

After confirming level alignment, technicians cleaned the surface and applied NexusPro® flexible sealant along all joints and cracks. The sealant’s UV-resistant formula ensures it stays flexible and watertight through Wisconsin’s temperature extremes. The result is a fast, low-disruption repair—completed in a single visit—that restored function, safety, and curb appeal to this Lac du Flambeau home.

During inspection, we found high humidity, signs of condensation on framing, and evidence of seasonal moisture rising through the soil. The crew graded and prepared the crawl space floor before installing CleanSpace®, custom-cut to fit the contours of the foundation. The reinforced liner was anchored and sealed along all seams and penetrations, forming a durable vapor barrier that locks out moisture.

Vents were sealed to prevent outdoor air exchange, and drainage matting was placed beneath the liner for improved airflow and water management. The finished encapsulation transformed a damp, uncomfortable crawl space into a clean, controlled environment—helping preserve the structure and deliver long-term indoor comfort for the Lac du Flambeau homeowner.

During inspection, we found clear evidence of water seepage along the wall-floor joint and an undersized sump system that couldn’t handle heavy inflow. The crew removed a narrow strip of concrete to install WaterGuard®, positioned just above the footing to intercept groundwater before it reached the slab surface. The system was connected to a TripleSafe® sump liner equipped with three pumps—primary, secondary, and battery backup—to ensure constant protection even during power outages.

To complete the waterproofing system, a Sedona™ high-efficiency dehumidifier was installed to automatically regulate humidity and keep the air fresh and dry. With WaterGuard, TripleSafe, and Sedona working together, this Lac du Flambeau home now has reliable, year-round basement protection designed for Wisconsin conditions.
