The Challenge: A Sinking Garage and a Busy Homeowner

In the quiet suburban neighborhood of White City, Oregon, lived a dedicated mechanical engineer whose demanding work schedule often extended into his evenings and weekends.

His garage wasn’t just a place to park his car; it was his sanctuary, a well-equipped workshop where he restored vintage motorcycles. However, over the past few years, a growing problem had begun to disrupt his routine and raise concerns about his property’s safety and value: the concrete driveway leading up to his garage was noticeably sinking.

What started as a minor dip had progressed into a significant depression, particularly near the garage entrance. The uneven concrete slabs created several issues:


Tripping Hazard: The differential in height between the sunken slabs and the adjacent, stable sections posed a clear tripping hazard, especially when he was moving tools or parts in and out of the garage.

Water Pooling: During rainstorms, water would collect in the sunken areas, creating large puddles that were slow to drain. This not only made for messy entry and exit but also raised concerns about water seeping into the garage or contributing to foundation issues over time.

Aesthetic Deterioration: The unsightly cracks and uneven surfaces significantly detracted from the curb appeal of his otherwise well-maintained home. He wanted to make sure this could be repaired without hurting his property value, and maybe even improve it!

Significant Gap at Doors:
As the driveway settled, a noticeable gap began to appear between the bottom of the garage doors and the concrete floor, allowing drafts, dust, and even small pests to enter the garage.

The Solution: TerraFirma’s Concrete Leveling with Polyurethane and NexusPro

The TerraFirma team arrived at the clients home and completed the entire Concrete Leveling process in less than a day, causing minimal disruption to his schedule.

The small injection holes were barely noticeable, and the rapid curing time of the polyurethane meant he could drive on his leveled driveway within hours of the work being completed.

Polyurethane Foam Injection

The core of the solution involved injecting a high-density, expanding polyurethane foam beneath the sunken concrete slabs. This process is far less disruptive than traditional mudjacking or concrete replacement.


NexusPro Joint Sealant

Once the concrete slabs were leveled, the next critical step was to seal the cracks and joints to prevent water intrusion and further erosion. NexusPro, a silicone-based sealant, was chosen for its superior performance.

The case of this sinking garage floor in White City, Oregon, stands as a compelling example of how modern concrete leveling techniques can effectively address structural and aesthetic challenges. By choosing TerraFirma’s polyurethane foam injection and NexusPro joint sealant, we not only resolved an immediate safety liability and restored their home’s beauty but also invested in a long-term solution that enhanced the home’s value and the owners quality of life.
