The Simpson CIPO32 CI-PO Paste-Over and Structural Repair Epoxy by Simpson is a fast-curing, two-component, high-modulus, high-solids, moisture-tolerant, thixotropic epoxy formulated to secure injection ports at the concrete surface prior to injection repair, and to perform general structural crack repair across a wide range of job-site conditions. Its gel-viscosity formulation bonds chemically with concrete on both dry and damp surfaces, while its convenient 32 oz. side-by-side cartridge dispenses cleanly through the included static mixing nozzle - keeping application fast and consistent from the first pull to the last.

Key Features

• Dispenses with standard crack injection (CI) dispensing tools - works directly with existing CI equipment, so there is no need for specialized or additional hardware on the job site.
• Chemically bonds with the concrete to provide a structural repair - delivers a true load-bearing fix rather than a surface-only patch, restoring the integrity of the repaired section.
• Gel-viscosity moisture-tolerant formulation - can be applied to both dry and damp concrete surfaces, reducing downtime spent waiting for substrates to fully dry.
• Non-shrink formulation - maintains full contact with the crack or void as it cures, preventing gaps that could compromise repair quality over time.
• Freeze-thaw resistant - holds up through repeated temperature cycling, making it a reliable choice for exterior and cold-climate concrete repair applications.
• Meets ASTM C881 and AASHTO M235, Type I, Grade 3, Class B and Type I/IV, Grade 3, Class C - complies with recognized industry standards, supporting use on regulated or inspected projects.
• NSF 61 listed for potable water applications - approved for use in environments with potable water contact, broadening the range of eligible repair sites.
• Includes AMN19Q mixing nozzle - the static mixing nozzle is included in the box, so the product is ready to dispense without sourcing additional components.

Why This Product

• One product, two critical functions - CI-PO is engineered specifically to paste over injection ports and serve as a structural repair epoxy, giving contractors a single material that handles both steps of a crack injection workflow without switching products.
• Formulated for real-world conditions - the moisture-tolerant, freeze-thaw resistant chemistry means repairs do not have to wait for perfect conditions; the epoxy performs on damp surfaces and stands up to the temperature swings that compromise lesser repair materials.
• NSF 61 listed for potable water contact - for repair projects involving water infrastructure or potable water systems, this listing opens doors to applications that many standard repair epoxies cannot legally or safely address.
• Seamless compatibility with the Simpson ecosystem - the 32 oz. side-by-side cartridge is compatible with Simpson Strong-Tie ADT30S and ADT30P dispensing tools, so teams already working with Simpson crack injection equipment can incorporate this epoxy into their process with no added setup.
