Project Overview
Location: Undisclosed
Client: Confidential
Contractor: United Structural Systems
Structural Consultant: Structural Reinforcement Solutions (SRS)
Scope: Parking garage structural repairs and reinforcement
The Solution: FRP++ for Parking Garage Structural Repair – Strength, Protection & Longevity
The Challenge: A Deteriorating Parking Garage
A multi-level parking garage serving a high-traffic residential/commercial property showed extensive concrete deterioration, shear cracks, and steel corrosion. Structural deficiencies in beams, columns, and slab connections posed serious safety concerns. The property owner needed a non-invasive, long-lasting repair solution to restore structural integrity without major disruption to operations.
The Solution: FRP++ – Strength, Protection & Longevity
SRS collaborated with United Structural Systems to develop a strategic repair plan utilizing FRP++, a reinforced structural system that integrates carbon fiber strengthening with concrete protection. This combination of materials and engineering expertise delivered a durable, high-performance solution for the garage.
Step-by-Step Parking Garage Structural Repair with FRP++
1. Condition Assessment & Engineering Support
Inspection & Analysis:
Structural assessments identified shear cracks, rebar corrosion, and beam spalling.
Load calculations determined which areas required reinforcement and shear strengthening.
Structural Crack Injection with SRS-3000 prior to Carbon Fiber Confinement
Customized Repair Plan:
SRS and United Structural Systems developed a targeted reinforcement strategy to restore integrity while minimizing downtime.

Column bases exhibiting spalling, cracks and section loss were treated with epoxy injection and patched to restore integrity before applying FRP reinforcement.
Steel Protection with SRS-4100 Steel Guard:
Vapor-phase corrosion inhibitors were applied to embedded rebar and steel connectors.
Reduced chloride migration to prevent future steel corrosion and degradation.

Columns were reinforced with FRP at the the base to provide additional confinement and shear strengthening, especially in load-bearing areas.
Crack Injection with SRS-3000 Epoxy Injection Resin:
Injected into cracks to restore internal structural integrity.
Provided a seamless repair before carbon fiber application.

2. Concrete Surface Preparation & Crack Injection
Concrete Guard Treatment (SRS-4000):
Strengthened existing concrete by reducing porosity and preventing future moisture infiltration.
Improved adhesion for FRP application, creating a stronger bond between the surface and reinforcement layers.

3. Carbon Fiber Reinforcement & Structural Strengthening
Beam & Column Reinforcement with SRS-600UNI & SRS-660BI Carbon Fiber:
Flexural reinforcement: SRS-600UNI was applied in multiple layers to restore and increase beam capacity.

Shear reinforcement: SRS-660UNI U-wraps were used to improve shear resistance and load distribution.
Column confinement: Full carbon fiber encapsulation at beam-column intersections reduced stress concentration and improved long-term durability
Steel members were used to connect reinforced sections of the structure, ensuring proper load transfer and stability.
4. Final Surface Protection & Long-Term Durability
Coating & Finish:
Applied a UV-resistant protective coating over FRP to enhance durability.
Minimal Disruption & Faster Completion:
No heavy demolition required, reducing downtime and occupant vacancy in the apartment building.
FRP++ system accelerated installation, allowing for a quicker return to full use.

The Results: A Stronger, More Resilient Parking Garage
✅ Enhanced Structural Capacity – Beams, columns, and slabs now exceed their original design strength.
✅ Corrosion Protection – Embedded steel reinforcement is safeguarded against long-term deterioration.
✅ Extended Lifespan – FRP++ reinforcement ensures the garage remains structurally sound for decades.
✅ Non-Invasive Application – Repairs were surface-applied, avoiding major disruptions.
"Working with SRS allowed us to implement cutting-edge carbon fiber strengthening and protective treatments that delivered an efficient and long-lasting solution."
