Stop Vehicle Scraping Sinking Cedar Rapids Driveway Lifted in Hours

Every time the homeowner in Cedar Rapids, IA pulled into their driveway, they faced the same cringe-inducing sound: their car bottoming out on a sudden, severe lip between concrete slabs. What started as small, unsealed gaps in the driveway had allowed rainwater to trickle beneath the surface over time. That water gradually washed away the supporting soil base, leaving hollow voids that caused heavy concrete panels to sink, tilt, and misalign.
Frustrated by the ongoing vehicle damage and worsening trip hazards, the homeowner called in expert help. System Design Specialist Chris Hebbel performed a thorough site inspection, diagnosing the root cause as subterranean soil erosion. Chris presented a fast, non-invasive lifting and sealing strategy to restore the driveway without the massive cost, mess, and downtime of tearing out and repouring concrete.
Foreman Justin Maddox Jr. and crew member Brantly arrived on site to bring the driveway back to level ground. The repair began by drilling small, pea-sized ports directly through the sunken concrete panels. Using our high-density PolyLevel® geopolymer injection system, the crew injected expanding polyurethane foam into the hidden voids below. The liquid foam reacted immediately, expanding to fill every gap, compact the loose subgrade soil, and gently push the heavy concrete slabs back into a completely flush alignment.
To make sure rainwater couldn't wash away the soil again, Justin and Brantly prepped and sealed all control joints and surface cracks using NexusPro® joint sealant. This advanced silicone sealant stays flexible during harsh Midwest temperature swings, resists sun degradation, and forms an airtight barrier against future water infiltration.
In just a single afternoon, the driveway was transformed into a smooth, safe entryway. The Cedar Rapids homeowner can now pull into their garage smoothly without scraping their vehicle—confident that their concrete is stabilized and protected for the long haul.
