Expert Crawl Space Repair & Basement Waterproofing Contractor Serving Kingsford, MI

Assessment:
Settlement had created voids under the interior garage slab (notably at the overhead door line) and under several walkway panels leading to the front entry. Open joints and cracks were allowing water to reach the base, accelerating washout and freeze–thaw damage.

Solution & Steps:

1. Lift & stabilize (PolyLevel®): We mapped lift points on the garage floor and walkway, then drilled small (~⅝") injection ports. Expanding polyurethane foam was injected in controlled increments while we monitored elevations with a laser, correcting pitch away from the garage and aligning the walkway to the stoop.

2. Seal & protect (NexusPro®): After lifting, we routed/cleaned the garage control joints, the overhead door joint, and walkway seams. We installed backer where needed and applied NexusPro to create a flexible, UV-resistant seal that keeps water out and tolerates U.P. temperature swings.

3. Finish: Injection ports were patched with non-shrink grout and the work areas were cleaned for a neat finish.

Outcome:
The garage floor now meets the door seal evenly and drains correctly; the front walkway is level with the stoop and free of trip edges. Most areas returned to foot traffic the same day, with vehicle traffic the following day—delivering a durable repair with minimal disruption.

During inspection, we confirmed active cold-joint seepage and elevated humidity. The solution combined water capture, reliable pumping, and air moisture control:

1. Perimeter capture: We saw-cut and installed WaterGuard® just beneath the slab edge along the leaking walls, pitching it to a new sump location for service access. Cleanout ports were added for future maintenance.

2. Pumping redundancy: We set a TripleSafe® liner with primary and secondary pumps, an airtight lid, check valves, and a dedicated battery-backup pump to protect the home during outages or extreme rainfall. Discharge was routed per code for dependable flow.

3. Humidity control: A Sedona dehumidifier was installed and set to a target RH. Its condensate line was routed to the sump for automatic removal, and airflow was arranged for even circulation across the basement.

4. Finish & verification: We restored the concrete over the WaterGuard trench, tested both main and backup pumps, verified alarm functions, and calibrated the Sedona. The homeowner received a simple maintenance guide and service schedule.

Outcome: The homeowner now has a permanent path for groundwater, robust pumping capacity with backup protection, and stable indoor humidity—delivering a dry, healthy basement and peace of mind.

Recently at Sure-Dry, we had the pleasure to tackle a residential project in the charming community of Kingsford, MI, that hit quite close to what many homeowners dread: unlevel concrete and multiple large cracks. For this particular homeowner, the problem was doubly troubling. They reported that the garage floor had significantly sunk on one side, creating a noticeable 1-inch drop that prevented the garage door from closing properly—a considerable security and insulation concern. Plus, the backyard patio had its woes, with an uneven dip allowing water to pool, negating any attempts at creating a backyard oasis. Our initial approach involved our diligent Customer Care team, who quickly set up a home inspection to dig into the issue at hand. After a detailed analysis conducted by one of our seasoned System Design Specialists, it was determined that the dual problem of the sunk garage floor and the improperly settled patio could find its remedy in our tried and trusted PolyLevel and NexusPro solutions. PolyLevel, an innovative foam injection, was designated to lift and level the garage floor to its original stature, ensuring that the garage door could close seamlessly once again. This bit of science seemed almost like magic—within hours, the floor was even, providing a solid, level foundation. To tackle the patio’s problem, we employed NexusPro, a sealant catered to filling joints and cracks, ensuring no further water could erode the patio’s foundation. This solution not only rectified the pooling issue but also enhanced the patio's overall aesthetic and longevity. As we wrapped up, the visible transformation was accompanied by the homeowner’s sigh of relief; their garage and patio were not just repaired but revitalized.
