Real-World Slabjacking & Concrete Repair Projects

This 55+ community featured large concrete walkways that had settled unevenly due to poor soil conditions. Within a few years, multiple slabs had sunk, creating tripping hazards and uneven walking surfaces that posed liability concerns for the condo association.

The concrete floor at this Massachusetts property had noticeably settled over two inches due to a winter water line break, which eroded the soil beneath the slab. The building had been vacant at the time, so the leak went undiscovered for an extended period, allowing the floor slab to continue settling.

The concrete floor of a ten-year-old residential home had settled more than three inches, creating uneven surfaces and structural concerns. Further investigation revealed a significant void beneath the slab, with exploratory drilling confirming void depths of 3 to 4 inches in multiple areas. Left unaddressed, the settlement risked continued movement and further deterioration of the concrete floor.

The concrete walkways surrounding the restaurant had experienced differential settlement, creating multiple pronounced tripping hazards where the sidewalk met the granite curbing. These uneven surfaces posed a serious safety risk to patrons and staff and exposed the property owner to potential liability. The issue was especially problematic given the restaurant’s high daily foot traffic and constant pedestrian flow during peak lunch and dinner hours.

During renovation work at an existing Harvard Graduate School building, construction crews uncovered a significant void beneath the basement concrete slab. The affected area was scheduled to be converted into a conference room, and the discovery occurred late in the renovation process. With the project already on a tight timeline, the unstable slab posed a serious structural and scheduling risk. Any delay would have jeopardized the completion of the space and disrupted ongoing campus activities.

Concrete walkways connecting three large commercial buildings had experienced differential settlement over time. Most notably, the slabs had tilted toward the buildings, causing water to drain and pool directly against the foundations. During winter months, snow melt would refreeze along these walkways, creating hazardous conditions for pedestrian traffic and increasing liability risks for the property owner.

Miles of concrete sidewalks throughout the apartment community had experienced differential settlement, resulting in numerous tripping hazards for residents and visitors. In addition, the pool patio area had also settled unevenly, creating further pedestrian safety concerns. These conditions not only posed a risk of injury but also exposed the property owner to increased liability across a large portion of the site.

Approximately four acres of concrete warehouse slabs were affected by a condition known as slab curling, where the edges of the slabs had curled upward over time. This curling led to cracking, joint deterioration, and uneven surfaces that were being subjected to constant heavy forklift traffic. The ongoing movement threatened further damage to the concrete and posed operational risks within the facility.

Compounding the issue, the warehouse housed an active distribution business that could not tolerate downtime, restricted access, or disruptive construction activities.

A frost-heaved concrete slab at the main entrance of the Westford Highway Department created a significant tripping hazard and liability concern for the Town. One section of the walkway had lifted nearly an inch during the winter months and failed to settle back in the spring, leaving an uneven walking surface directly in a high-traffic pedestrian area. Because the hazard was unavoidable for visitors and staff entering the building, the condition posed both a safety risk and an immediate exposure to potential injury claims.
