UNISORB CONCRETE REPAIR COMPOUND

Unisorb Concrete Repair Compound (URCR) is designed for use in making fast repairs of concrete floors, aisle ways and drives. It is also excellent for patching and filling chuck holes and for quick setting of anchors. Depending on the application, repairs made with UCRC can be used in as little as one hour. After a three hour cure it is as good as most concrete floors (3900 psi compression)

UCRC is self-sealing and requires no sealant when used out doors, unlike most cementitious products.

Rapid-Set Concrete Repair for Industrial Floors, Foundations and Anchoring
Unisorb UCRC (Unisorb Concrete Repair Compound) is a high-performance, Portland cement-based repair material engineered for fast, durable restoration of concrete surfaces in industrial environments. Reinforced with synthetic fibers, UCRC delivers exceptional bonding strength and structural integrity for filling voids, repairing cracks, and preparing foundations for anchoring and grouting.

Designed for rapid return-to-service applications, UCRC sets quickly—allowing for fast anchor placement and minimizing downtime. Its accelerated cure profile makes it ideal for high-traffic areas, including surfaces subject to wheeled equipment, where quick turnaround is critical.

UCRC is available in both regular set and extended set formulations. The standard version is extremely fast-setting—requiring placement within minutes—while the extended set provides additional working time for larger repairs and placements.

Engineered for durability, UCRC is resistant to water and environmental exposure once cured, making it suitable for demanding industrial conditions. (Note: installation should be performed above freezing temperatures.)

UCRC provides a reliable, high-strength solution for concrete repair and preparation—ensuring a solid foundation for anchoring, grouting, and continued operation.
