Commercial Retaining Wall Repair & Strengthening With Carbon Fiber

Originally constructed during WWII when steel reinforcement was difficult to source, the 60-foot retaining wall at Occidental College exhibited significant cracking, spalling, and structural deterioration after decades of service. As various spot repairs failed over time, the wall required a modern strengthening method capable of restoring capacity without extensive demolition.

Structural Reinforcement Solutions (SRS) was selected to design a long-term repair approach using Carbon Fiber Reinforced Polymer (CFRP). SRS-600UNI was specified to provide vertical flexural strengthening, while 12" wide SRS-660BI was used for horizontal confinement, anchorage, and crack repair along the wall. This combination delivered increased stability and redistributed loads across weakened sections of the existing wall.

Prior to CFRP installation, deteriorated concrete was removed and replaced to achieve a smooth bonding surface. Once strengthened, the wall was coated to restore an aesthetically uniform finish. This comprehensive repair ensured the wall could safely handle future reinforcement demands, including potential tieback installations, while eliminating safety concerns associated with aging infrastructure.
