The Simpson CI-LV FS Fast-Setting Low-Viscosity Structural Injection Epoxy (CILVFS32) from Simpson Strong-Tie is a two-component, high-modulus, high-solids, moisture-tolerant epoxy specially designed for pressure injection of concrete cracks and for increasing the bond between freshly placed repair mortars or concrete mixes and existing concrete when substrate temperatures are between 40 deg.F (4 deg.C) and 90 deg.F (32 deg.C). Dispensed through a static mixing nozzle via a side-by-side cartridge system, this epoxy chemically bonds with concrete to deliver true structural repairs while sealing cracks against moisture intrusion and protecting embedded rebar from corrosion.

Key Features

• Meets the requirements of ASTM C881 & AASHTO M235, Type I/II, Grade 1, Class B and ASTM C881 & AASHTO M235, Type I/IV and II/V, Grade 1, Class C
• Chemically bonds with the concrete to provide a structural repair; CI-LV FS seals the crack from moisture, protecting rebar in the concrete from corrosion
• Moisture-tolerant; can be used on dry and damp surfaces
• Low surface tension allows the material to effectively penetrate narrow cracks
• Formulated for maximum penetration under pressure
• Suitable for pressure injection or gravity-feed applications
• Non-shrink and resistant to oils, salts and mild chemicals
• Can be used with metered pressure-injection equipment
• Freeze-thaw resistant
• 32-oz. cartridge

Frequently Asked Questions

What types of surfaces can the CI-LV FS epoxy be applied to?

The CI-LV FS epoxy is moisture-tolerant and can be used on both dry and damp concrete surfaces, making it suitable for a wide range of field conditions without requiring a fully dry substrate before application.

What crack widths is this epoxy designed to repair?

CI-LV FS is formulated as a low-viscosity epoxy (600 cP) with low surface tension, making it effective for repairing fine- to medium-width cracks ranging from 1/64" to 1/4" (0.4 - 6 mm) in width. Its viscosity allows maximum penetration under pressure into narrow cracks.

What dispensing tools are compatible with the CILVFS32 cartridge?

The 32-oz. side-by-side cartridge is compatible with Simpson Strong-Tie ADT30S and ADT30P dispensing tools, which include both manual and pneumatic options, and is dispensed through a static mixing nozzle. The EMNO22 mixing nozzle is included with the cartridge.

What industry standards does this epoxy meet?

CI-LV FS meets the requirements of ASTM C881 & AASHTO M235, Type I/II, Grade 1, Class B as well as ASTM C881 & AASHTO M235, Type I/IV and II/V, Grade 1, Class C, ensuring it meets rigorous performance criteria for structural concrete repair applications.
