SRS 660BI Structural Carbon Fiber - Bulk Repair Kit
The SRS-660BI Carbon Fiber System is a high-strength, bidirectional 660 gsm CFRP fabric engineered for structural strengthening and rehabilitation of concrete, masonry, and timber elements. With a balanced 0°/90° fiber orientation, high tensile capacity, and predictable performance, SRS-660BI is ideal for both engineered FRP strengthening designs and contractor-installed reinforcement applications. Typical uses include slab strengthening, shear wall upgrades, punching shear reinforcement, and restoration of deteriorated structural members.
SRS-660BI bonds externally to structural members using SRS-1000 Structural Epoxy Resin, forming a composite system that increases load-carrying capacity, enhances shear and flexural performance, and improves the long-term serviceability of concrete structures. The system is commonly used in commercial, industrial, municipal, and residential structural repair projects requiring reliable, low-profile reinforcement.
Applications
The SRS-660BI Carbon Fiber system is used in a wide range of structural strengthening projects involving concrete, masonry, wood, and select steel components. Designed for compatibility with epoxy-based FRP systems, it is commonly used in:
Structural Strengthening
- Increase flexural capacity of slabs, decks, and joists
- Strengthen elevated parking structures and floor systems
- Provide bidirectional reinforcement for multi-directional load demands
- Reinforce deteriorated or under-reinforced concrete members
Shear & Crack Control
- Improve shear resistance on beams, walls, and slab-column connections
- Limit crack propagation in concrete or masonry elements
- Provide multidirectional crack stabilization before overlays or repairs
Slab & Punching Shear Reinforcement
- Upgrade punching shear resistance around concrete columns
- Improve slab performance where two-way strengthening is required
- Enhance load distribution using balanced 0°/90° reinforcement
Column, Pier & Wall Strengthening
- Bidirectional wrapping for confinement, ductility, and shear enhancement
- Improve axial performance of columns, piers, and pilasters
- Strengthen retaining walls, shear walls, and basement walls
Rehabilitation & Restoration
- Extend service life of aging or deteriorated concrete structures
- Strengthen corroded, cracked, or impact-damaged members
- Reinforce structures for change-of-use, added loads, or retrofit upgrades
