Project Summary: Signarama’s 2,734-square-foot facility experienced foundation movement that threatened both the structure and newly installed epoxy flooring. Pinnacle supported the foundation using double-walled steel piers installed via tunneling, restoring elevation while minimizing disruption and setting the building up for long-term protection.
Client: Signarama
Client Industry: Signage Manufacturing
Building Size: 2,734 sq ft
Foundation Repair Services: Steel Pier, Tunneling
Problem
When the commercial client first reached out, several warning signs were already visible throughout the building. Cracked walls and floors, uneven and sloping surfaces, and doors that no longer operated smoothly all pointed to underlying foundation movement. The situation became even more concerning as sections of the floor began separating from the walls, and recently epoxied floors started showing new cracks—something the client had invested in protecting and preserving.
Pinnacle had previously completed repairs on another area of the building, which were still holding up in excellent condition. Because of that positive experience, Signarama reached back out for an estimate when new issues arose. With a newly installed epoxy floor at risk of further damage, they knew the issue needed to be addressed quickly—before conditions worsened and repairs became more extensive.
Solution
To diagnose the issue, the Pinnacle team conducted a new elevation study of the commercial property, comparing current measurements to previous data to accurately assess movement and determine the severity of the foundation settlement. Based on these findings, double-walled steel piers installed via tunneling were recommended, with an alternative option to break through the interior slab also presented. Tunneling was ultimately selected to minimize disruption to daily operations, protect the newly installed epoxy flooring, and prevent dust that could damage the business’s sensitive print equipment—allowing work to continue without requiring a shutdown.
The repairs were completed over the course of five days and required the installation of interior piers, driven to a depth of 18 feet for long-term support. During the project, the team encountered an unexpected challenge when an interior beam believed to run continuously across the building was found to be segmented, necessitating the addition of two extra doublewalled steel piers. Using a combination of tunneling techniques, angle iron, and double-walled steel piers, the team successfully supported the foundation while minimizing impact to the facility and its operations.
Outcome
Upon completion of the repairs, the foundation was successfully leveled, achieving a one-inch elevation gain in the affected area. A follow-up inspection confirmed the effectiveness of the support efforts, and subsequent plumbing testing identified a leak that had contributed to the issue. With the structure properly supported and elevation restored, the client now has a clear path to address the plumbing repair—helping prevent future movement and protect the commercial asset long term.
