Unisorb Concrete Repair Compound (UCRC) is a precision-engineered, cement-based flowable repair system designed to deliver reliable structural performance in demanding concrete restoration, anchor setting, and crack repair applications. Engineered for high-traffic environments where concrete surfaces are exposed to heavy loads, weather extremes, or frequent wear, this fast-setting formulation provides exceptional strength and durability without compromising installation efficiency. With superior flowability and self-sealing properties, it easily fills cracks, holes, and voids in concrete floors, foundations, sidewalks, and roadways — requiring no pre-wetting or external sealants for outdoor applications.
This repair compound reaches 2,700 psi compressive strength in just one hour and can be opened to traffic within 20 minutes to one hour after placement, helping minimize costly downtime and project delays. Its poly fiber reinforcement system, combined with excellent bond strength and thermal stability, ensures long-term structural integrity and resistance to scaling and freeze-thaw cycles. Ideal for industrial maintenance operations and infrastructure repair, Unisorb Concrete Repair Compound simplifies installation while maintaining commercial-grade mechanical performance under demanding service conditions.

Frequently Asked Questions
What is the recommended pour depth for Unisorb Concrete Repair Compound?
The typical pour depth ranges from 1/2 inch to 2 inches. For thicknesses exceeding 2-3 inches, add 3/8″ pea gravel at a ratio of 1 part gravel to 2 parts compound by weight.
How long before the repaired area can handle traffic?
Under typical conditions (72°F), repairs can be opened to light traffic in 20 minutes and heavy traffic in 1 hour. Full strength is achieved in 28 days.
What type of surface preparation is required?
Remove all oil, grease, and contaminated concrete. Scarify surfaces to remove unsound material and expose aggregate. The repair area should be chipped to a minimum depth of 1/2 inch.
How much water should be mixed with the compound?
Mix 6.5 quarts of water per 100 pounds of dry powder. Follow exact ratios for optimal performance and only mix the amount needed for immediate use.
Can it be used in extreme temperatures?
Use standard high-temperature concrete techniques for conditions over 90°F and low-temperature techniques for conditions below 45°F to ensure proper curing.
What is the shelf life and packaging?
Available in convenient 50-pound resealable pails with a yield of 0.40 cubic feet (691 cubic inches) per pail. Store in original packaging in dry conditions.
