Your Dependable Crandon, WI Sinking Foundation & Crawl Space Professionals

In Crandon, a homeowner noticed their front walk and sections of the driveway had sunk over time, leaving toe-stubbing edges and open joints that funneled water toward the garage. After storms, puddles formed where slabs had settled, and in winter the freeze–thaw cycle expanded cracks and worsened the unevenness. They wanted a long-lasting fix without the cost and mess of full replacement.

Our crew recommended a two-step solution. First, we used PolyLevel®, a high-density expanding foam, to stabilize the base soils, fill hidden voids, and lift the slabs with precision. We mapped low areas, drilled small (penny-size) injection ports, and monitored lift with levels to restore proper drainage away from the home. Next, we protected the repair by sealing joints and cracks with NexusPro®, which stays flexible through temperature swings and resists UV breakdown. Where needed, we installed backer, applied NexusPro, and broadcast color-match sand so the sealed joints blend with the surrounding concrete.

By the end of the day, the slabs were level and the joints were sealed—improving safety, curb appeal, and long-term durability without tearing out and replacing the concrete.

In Crandon, repeated spring and summer storms left a homeowner with damp edges along the basement floor and a musty smell that crept into the living space. Boxes had been moved onto shelves, and part of the basement went unused. The biggest concern was reliability—if the power blinked during a downpour, their old pump might not run.

Our team recommended a two-part fix focused on managing water at its entry point and ensuring dependable removal. We installed WaterGuard® along the interior perimeter to capture groundwater right where it enters—the wall–floor (cove) joint—so it never reaches the surface. That drainage ties directly into a new UltraSump® system equipped with battery backup, a sealed lid, and alarm notification for added protection and cleanliness.

With WaterGuard and UltraSump working together, the basement remains clean and dry after storms, storage is protected, and the homeowner has confidence that even a power outage won’t compromise their home.

In Crandon, a homeowner noticed persistent musty odors and chilly floors above the crawl space. During wet weather, humidity spiked and light condensation formed on joists and ductwork. Winter made things worse: drafts at the rim joists fed cold air into the home, raising heating costs and discomfort.

Our team designed a comprehensive fix centered on moisture control, insulation, and air sealing. We installed CleanSpace® to separate the home from earth moisture and create a durable, continuous vapor barrier across the floor and up the walls, wrapping piers and sealing every seam. We added SilverGlo® insulation to the crawl space walls to boost R-value and reflect radiant heat back into the space. To cut drafts, we sealed the perimeter with RimTight™ at the rim joists. Finally, we placed an UltraSump® in the low spot to manage groundwater with reliable pumping protection and battery backup.

With these upgrades working together, the crawl space maintains a stable, dry environment. The main floor feels warmer, odors are gone, and the homeowner has lasting protection against moisture and seasonal temperature swings.

In Crandon, a homeowner called after spotting step-cracks and a slight inward lean along one side of their crawl space. During wet stretches, the movement was more noticeable and the family began to feel springiness in the floor above. They wanted a permanent, minimally invasive fix that didn’t require exterior excavation.

Our team recommended PowerBrace™ for interior stabilization. After documenting wall deflection and mapping joist locations for proper load transfer, we set zinc-coated steel I-beams against the failing wall, anchored them at the base, and fastened adjustable brackets to the floor system. This approach delivers immediate stabilization and, importantly, gives the option to tighten the system during scheduled service to encourage gradual realignment as conditions allow.

The result is a secure crawl space wall and a steadier floor system—delivered with minimal disruption and a clean, serviceable installation.

During inspection, we confirmed crawl space settlement: undersized pads on compressible soil, deflecting joists, and a main girder spanning longer than intended. To correct the structure efficiently, we recommended SmartJacks®.

Installation steps:

1. Layout & prep: Mapped support points to reduce spans and target the worst deflection; excavated to competent subgrade.

2. Engineered footings: Placed compacted stone and set concrete/steel bases to spread loads and prevent future settlement.

3. Set supports: Installed galvanized SmartJack posts beneath the main beam; added a supplemental steel beam for continuous bearing where needed.

4. Lift & level: Tightened the system gradually, using a laser to guide small, even lifts that closed gaps and corrected floor slope while protecting finishes.

5. Finalization: Locked hardware, recorded reference elevations, and reviewed a simple maintenance plan for periodic checks or adjustments.

Outcome: Floors are firm and level, doors operate correctly, and the homeowner has a code-compliant, adjustable solution that stabilizes the foundation for the long term.

The concrete patio of a home in Crandon, WI was sunken and uneven, creating trip hazards for the elderly homeowners as well as uneven space for their patio furniture. These homeowners needed a solution to lift and level the concrete slabs so that they could feel safe using the space again.

Sure-Dry lifted and leveled their concrete patio slabs using our patented PolyLEVEL system. PolyLEVEL is a two-part expanding polyurethane foam that is injected beneath the concrete to fill the gaps caused by soil erosion and shrinkage. PolyLEVEL is designed to raise concrete slabs that have sunken and proactively protect concrete by filling voids and compressing loosely compacted fill soils in areas where concrete slabs have not yet begun to sink.

Richard's home in Crandon, WI had a major problem.  Years of water getting into his crawl space was causing endless issues.  The moisture was creating mold, there was a musty smell wafting from the crawl space to the rest of the home, and the wood floor joyces and other organic material in the crawl space were getting wet and were in danger of eventually failing.  Bottom line: Richard's crawl space was a disaster.  With no easy way to access the crawl space himself, Richard needed the help of professionals.  That is when Richard decided to call Sure-Dry Basement Systems, who offered Richard the perfect solution to his crawl space problems.  

Sure-Dry offered Richard a comprehensive solution to his crawl space problem whose main components were: crawl space encapsulation, drainage matting, installation of a SmartSump sump pump, vent covers, Aprilaire Dehumidifier, and a Turtl crawl space entry system. 

Encapsulating the crawl space created a vapor barrier that prevented any future water from getting into Richard's crawl space.  Drainage matting allows for the water that comes in behind the vapor barrier an easy way to drain out and away.  By installing a SmartSump sump pump, that water that the drainage matting allows to drain beneath the vapor barrier has a place to drain to and discharge away from the home.  The Aprilaire dehumidifier will remove the excess moisture up to 70-120 pints per day, eliminate the musty smell, and prevent any further mold damage.  And with a Turtl crawl space entry system, Richard now has easy access to his crawl space.  

There is no doubt that Richard can now have peace-of-mind knowing his crawl space issues are a thing of the past, thanks to Sure-Dry Basement Systems.
