Simpson CILVFS3KT CI-LV FS Fast-Setting Low-Viscosity Structural Injection Epoxy (3-gal. Kit) by 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). Its low viscosity and low surface tension allow it to deeply penetrate narrow cracks under pressure, delivering a chemically bonded structural repair that seals out moisture and protects 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
• 3-gal. kit

Frequently Asked Questions

What substrate temperature range is required when using CI-LV FS?

CI-LV FS is designed for use when substrate temperatures are between 40 deg.F (4 deg.C) and 90 deg.F (32 deg.C), making it suitable for a wide range of job-site conditions.

Can CI-LV FS be used on wet or damp concrete surfaces?

Yes. CI-LV FS is moisture-tolerant and can be used on both dry and damp surfaces, allowing repairs to proceed even when complete surface drying is not possible.

What crack widths is CI-LV FS formulated to repair?

CI-LV FS is formulated as a low-viscosity epoxy (600 cP) for repair of fine- to medium-width cracks ranging from 1/64" to 1/4" (0.4-6 mm) in width. Its low surface tension allows the material to effectively penetrate narrow cracks under pressure.

What is included in the 3-gallon kit?

The 3-gallon kit includes (2) 1 US gallon (3.8 L) cans of Component "A" (CILV1A) and (1) 1 US gallon (3.8 L) can of Component "B" (CILVFS1B), providing everything needed to mix and apply the two-component epoxy system.
