Uneven driveways, sidewalks, and patios on Mercer Island can be more than just an eyesore; they pose a significant safety hazard.

"My 1982 aggregate Driveway had cracked over the many years. Large sections raised and some had sunk. I had started to ask visitors to not park on my driveway. Trip hazards in every direction. The Groundworks crew used their innovative equipment to level the chunks then inject their magically strong foam to restore my driveway surface to level. A week or so later Groundworks returned to fill the cracks with river rock and finish. I'm very happy with the results and come this next Halloween I won't have to worry about trick or treaters tripping and falling!"

Common Causes of your Concrete Problems in Mercer Island

Cracks appearing in your driveway or patio? Many homes in this area experience concrete settling due to the unique soil composition and climate conditions found on Mercer Island. Local soils often contain a mix of clay and silt, which are prone to expand and contract based on moisture levels. With the region's frequent rains and periodic dry spells, the soil beneath your home can shift significantly. This movement, especially over time, leads to concrete slabs settling unevenly or sinking, causing visible surface cracks and misalignment. Additionally, homes on sloped lots or properties with historical fill material are particularly susceptible to these shifts.

These changes in the ground place stress on your concrete surfaces, sometimes making driveways, walkways, and patios uneven or unstable. Left unchecked, this can lead to severe foundation issues, such as misaligned doors or windows and water pooling against your home. Recognizing these warning signs early—such as hairline cracks and uneven surfaces—allows for timely intervention, potentially saving you from more extensive repairs. Addressing the problem sooner rather than later helps sustain the structural integrity of your home, keeping it safe and level.
