Simpson CI-SLV Super-Low-Viscosity Structural Injection Epoxy (3-Gallon Bulk Kit) by Simpson Strong-Tie is a two-component, high-modulus, high-solids, moisture-tolerant epoxy specially designed for pressure injection, gravity feeding, and flood coat filling of concrete cracks when substrate temperatures are between 60 deg.F (16 deg.C) and 90 deg.F (32 deg.C). This bulk kit delivers professional-grade structural repair performance, chemically bonding with concrete to seal cracks from moisture and protect embedded rebar from corrosion.

Key Features

• Meets the requirements of ASTM C881 & AASHTO M235, Type I/IV, Grade 1, Class C
• Chemically bonds with the concrete to provide a structural repair; CI-SLV 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 makes CI-SLV suitable for repairing very narrow concrete cracks?

CI-SLV features a low viscosity of 150 cP and low surface tension, which together allow the material to effectively penetrate narrow cracks as small as 0.002" (hairline cracks) and up to 1/4" (6 mm) in width. It is also formulated for maximum penetration under pressure, making it highly effective in pressure-injection applications.

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

Yes. CI-SLV is moisture-tolerant and can be used on both dry and damp surfaces, making it well suited for real-world concrete repair conditions where complete drying may not be possible.

What industry standards does CI-SLV meet?

CI-SLV meets the requirements of ASTM C881 and AASHTO M235, Type I/IV, Grade 1, Class C, confirming its suitability for structural concrete repair applications in demanding environments.

What components are included in the CISLV3KT bulk kit?

The 3-gallon bulk kit includes two 1 US gallon (3.8 L) cans of Component "A" (CISLV1A) and one 1 US gallon (3.8 L) can of Component "B" (CISLV1B), providing a complete two-component epoxy system ready for use with metered pressure-injection equipment or other compatible dispensing methods.
