Before & After Photos

The customer was wanting to prevent mold and reduce odors in their crawlspace. CleanSpace was installed, along with drainage matting, a discharge line and SuperSump pump.

This project showcases a crawl space encapsulation completed at a home in Park City, Utah, designed to protect the structure from excess moisture, cold air intrusion, and long-term foundation issues.

Before encapsulation, the crawl space had exposed soil and outdated vapor protection, allowing ground moisture to rise into the home. This can contribute to higher humidity levels, musty odors, cold floors, and potential wood rot or mold growth — especially in mountain climates like Park City where snowmelt and seasonal moisture are common.

After installation, the crawl space was fully sealed with a heavy-duty vapor barrier system, covering the ground and foundation walls to block moisture and improve overall air quality. Encapsulation helps regulate temperatures, protects floor joists and support beams, and improves energy efficiency by keeping cold air out during Utah’s long winters.

Crawl space encapsulation is an effective solution for homeowners in Park City looking to:

• Reduce moisture and humidity

• Prevent mold and wood decay

• Improve indoor air quality

• Increase comfort and energy efficiency

• Protect the home’s foundation long-term

Curtis, a homeowner in Garden City, UT, reached out because he was concerned about standing water in the crawlspace of his home. During a free inspection, our team confirmed the homeowner's moisture related concerns and identified elevated humidity levels that could lead to mold growth and long-term damage. To create a healthier, drier environment, we completed a crawlspace encapsulation. Our crew installed a durable vapor barrier along the floors and walls to help seal out moisture, reduce humidity, and keep debris from entering the crawlspace.

Using Nexus pro to seal the joints and cracks in this driveway in Cottonwood heights

At first, the homeowners noticed only a few small cracks in their driveway. But over time, those minor imperfections turned into large gaps and sinking slabs, making their property not only unsightly but also dangerous. Their garage floor had become noticeably uneven, and their carport had sunk by nearly three inches, creating a serious tripping hazard.

Beyond aesthetics, these issues raised serious concerns. Every time it rained, water seeped into the cracks, threatening to erode the soil beneath and worsen the problem. The homeowners knew that if left unaddressed, the damage could compromise the structural integrity of their home and reduce property value. They needed a long-term fix—not just another temporary repair.

Exploring Repair Options

Determined to solve the problem, the homeowners started researching their options. They initially considered DIY solutions, looking into store-bought sealants and self-applied fillers. However, they quickly learned that urethane-based products tend to crack, dry out, and deteriorate over time, meaning they would have to reapply them frequently.

They also explored traditional mudjacking, a process that injects a heavy slurry beneath the slab to lift it. However, after learning that mudjacking can break down over time, they realized it wasn’t the permanent solution they needed. Frustrated with limited options, they searched for an expert team that could provide a professional, lasting repair.

Choosing Davenport Foundation Repair

After reading customer reviews and case studies, the homeowners discovered Davenport Foundation Repair. They were impressed by the company’s expertise and reputation for delivering high-quality, long-term solutions.

Davenport’s team conducted a free inspection, thoroughly assessing the sinking and cracking issues. They explained that the damage was caused by soil compression and washout, creating voids beneath the concrete. Unlike other contractors who only suggested surface repairs, Davenport provided a comprehensive plan that would lift, level, and protect the concrete from further damage.

The recommended solution included:
✅ PolyLevel® Injection Foam to lift and stabilize the sinking slabs
✅ NexusPro Sealant to permanently seal the cracks and prevent moisture intrusion

Confident in Davenport’s expertise and transparent approach, the homeowners agreed to move forward with the repairs.

The Repair Process

Davenport Foundation Repair’s team arrived promptly and completed the project in just one day, minimizing disruption.

Step 1: Concrete Lifting with PolyLevel®

• The crew drilled small, precise holes in the sunken slabs.
• PolyLevel® foam was injected, expanding to fill the voids beneath and gently lifting the concrete back to its original position.
• Unlike mudjacking, PolyLevel® is lightweight, durable, and won’t degrade over time.
• The lifting process was completed in a matter of hours, with no heavy equipment or messy disruption.

Step 2: Crack Sealing with NexusPro

• All existing cracks and joints were thoroughly cleaned and prepped.
• NexusPro, a silicone-based sealant, was applied to create a flexible, weather-resistant barrier.
• Unlike traditional urethane caulk, NexusPro resists UV exposure, meaning it won’t dry out or crack.
• A thin layer of native sand was applied for a seamless finish, making the repaired areas blend naturally with the surrounding concrete.

A Smoother, Safer Space

By the end of the day, the transformation was clear. The once-sinking concrete was now fully level, eliminating the tripping hazards and restoring the home’s curb appeal. The cracks were permanently sealed, preventing future water damage and ensuring that the underlying soil remained stable.

With NexusPro curing in just 60 minutes, the homeowners could use their driveway and garage the same day—without worrying about extended downtime.

Why Timely Repairs Matter

This project proved how important it is to act early when concrete problems arise. If the homeowners had waited any longer, the sinking could have worsened, leading to more costly and invasive repairs. By addressing the issue now, they not only protected their home’s structural integrity but also saved thousands in potential future costs.

Davenport Foundation Repair provided a lasting solution, giving the homeowners peace of mind that their concrete surfaces would remain strong and stable for years to come.
