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 Need stamped engineering design, FRP layout drawings, or project-specific calculations?
