Simpson CI-GV Structural Injection Epoxy Gel from Simpson is a two-component, high-modulus, high-solids, moisture-tolerant, thixotropic epoxy engineered for pressure injection of concrete cracks. Dispensed through a static mixing nozzle via a manual or pneumatic dispensing tool, CI-GV delivers a chemically bonded structural repair for vertical and horizontal crack sealing and general concrete repair applications - making it a dependable choice for contractors and restoration professionals working across a wide range of concrete repair scenarios.

Key Features

• Gel viscosity that decreases under pressure - the epoxy flows more freely during injection, allowing it to penetrate and fill cracks more thoroughly for a complete, reliable repair.
• Chemically bonds with concrete to provide a structural repair - CI-GV seals the crack from moisture, protecting embedded rebar from corrosion and restoring the structural integrity of the concrete.
• Moisture-tolerant gel formula - works on both dry and damp surfaces, so job-site conditions are less likely to interrupt or delay the repair process.
• Non-shrink after curing and resistant to oils, salts, and mild chemicals - the cured repair holds its volume and stands up to common environmental stressors, supporting long-term durability.
• Freeze-thaw resistant - the cured epoxy withstands repeated freeze-thaw cycles, making it suitable for exterior concrete repairs in climates with seasonal temperature swings.
• Compatible with metered pressure-injection equipment and Simpson dispensing tools - works with the Simpson ADT30S and ADT30P dispensing tools, giving users flexible application options whether using manual or pneumatic equipment.
• Meets ASTM C881 and AASHTO M235 standards - compliance with multiple type, grade, and class designations confirms the product meets established performance benchmarks for structural epoxy adhesives.
• Includes EMNO22 mixing nozzle - the static mixing nozzle is included, so the two components are uniformly blended at the point of application without additional mixing steps.

Why This Product

• Structural-grade repair in a convenient cartridge format - CI-GV provides a high-modulus, high-solids epoxy repair that chemically bonds to concrete, delivering true structural restoration rather than a surface-level patch - all from an easy-to-handle 32 oz. side-by-side cartridge.
• Versatile enough for wet and dry job sites - because CI-GV is gel-viscosity and moisture-tolerant, it adheres to both dry and damp concrete surfaces, reducing delays caused by surface moisture and expanding the range of conditions where it can be effectively applied.
• Built-in corrosion protection for reinforced concrete - by sealing cracks from moisture infiltration, CI-GV actively shields embedded rebar from the corrosion that accelerates concrete deterioration, helping extend the service life of the repaired structure.
• Proven compliance with recognized industry standards - meeting multiple ASTM C881 and AASHTO M235 classifications gives engineers, inspectors, and contractors confidence that CI-GV performs to independently verified criteria for structural concrete crack injection.
