The Simpson CI-LV/CI-PO Crack Injection Contractor Kit (CI-LVPO-KT) by Simpson Strong-Tie is a complete, commercial-grade solution engineered for professionals performing structural concrete crack repairs on mid- to large-sized projects. This all-in-one epoxy injection kit combines a low-viscosity structural epoxy with a paste-over epoxy and every accessory needed to pressure-inject or gravity-feed cracks in concrete - delivering a reliable, field-ready package that eliminates the guesswork of sourcing individual components. Capable of repairing approximately 30 linear feet of 1/16 in. wide cracks in 8 in. thick concrete, this contractor kit is built for efficiency on demanding jobsites.

Key Features

• All-in-one package - includes CI-LV epoxy, CI-PO paste, injection ports, mixing tubes and accessories, so contractors arrive on-site fully equipped without sourcing components separately
• Low-viscosity (350 cP) epoxy - penetrates hairline cracks as narrow as 0.002 in. (0.051 mm) up to 0.25 in. (6 mm), making it effective across a wide range of concrete crack widths and conditions
• Covers approximately 30 feet of 1/16 in. wide cracks in 8 in. thick concrete - gives contractors a reliable coverage benchmark for estimating mid- to large-sized structural repair jobs (coverage may vary depending on crack condition and application method)
• E-Z-Click injection port system - flush-mount and corner-mount/drilled-in ports included, allowing versatile port placement on different crack geometries without additional hardware
• Multiple nozzle types included - Optimix mixing nozzles and adhesive mixing nozzles are both in the kit, ensuring proper mixing ratios and clean delivery for both the CI-LV epoxy and CI-PO paste
• Made in the United States - manufactured to meet the quality standards expected of commercial structural repair applications

Why This Product

• Handles the crack widths you actually encounter in the field - the 350 cP low-viscosity epoxy addresses hairline cracks at 0.002 in. all the way up to 0.25 in. wide, so a single kit covers the range of crack conditions typical on structural concrete repair jobs
• Saves time and simplifies procurement - rather than sourcing CI-LV cartridges, CI-PO cartridges, ports, fittings, and nozzles separately, everything is consolidated into one package, reducing pre-job preparation time and the risk of arriving on-site missing a component
• Scaled for mid- to large-sized structural repairs - with four 32 oz. CI-LV cartridges, two 32 oz. CI-PO cartridges, 60 flush-mount ports, 20 corner-mount ports, and 17 mixing nozzles, the kit provides enough material to complete substantial concrete crack repair work without running short
• Designed for two distinct injection methods - suitable for both pressure-injection of cracks in structural concrete and gravity-feed of horizontal concrete cracks, giving contractors flexibility based on crack orientation and site conditions

Frequently Asked Questions

What is the narrowest crack width this kit can repair?

The CI-LV low-viscosity epoxy included in this kit has a viscosity of 350 cP, which allows it to penetrate hairline cracks as narrow as 0.002 in. (0.051 mm). It can address cracks up to 0.25 in. (6 mm) wide, covering the range of crack widths most commonly encountered in structural concrete repair.

How much coverage does this contractor kit provide?

This kit is formulated to repair approximately 30 feet of 1/16 in. wide cracks in 8 in. thick concrete. Coverage may vary depending on crack condition and application method, so actual yield on a specific job may differ based on crack width, depth, and porosity.

What is the difference between the CI-LV epoxy and the CI-PO paste included in this kit?

The CI-LV is a low-viscosity structural injection epoxy used to fill and structurally bond cracks from within - injected under pressure or by gravity feed through the included ports. The CI-PO is a paste-over and structural repair epoxy, which is applied to the surface of the crack to seal it and serve as the bond line for the injection ports before epoxy is injected.

What types of injection ports are included, and what is each used for?

The kit includes two types of E-Z-Click injection ports. The 60 EIP-EZA flush-mount ports are used on flat, accessible concrete surfaces. The 20 EIPX-EZ corner-mount/drilled-in ports are designed for use at corners or locations where a drilled-in approach is needed, giving contractors flexibility based on the geometry and accessibility of the crack being repaired.
