Make repairs with Roadware 10 Minute Concrete Mender.
You can now repair cracks and spalls to a smooth finish in a fraction of the time it takes with ordinary products. Roadware 10 Minute Concrete Mender is a revolutionary new two-part hybrid urethane for repairing concrete. It is nearly water-thin for deep penetration, and it won’t pop out like epoxy because it never gets brittle.
What makes Roadware 10 Minute Concrete Mender different from other concrete repair products?
![]() Roadware 10 Minute Concrete Mender™ is a two-part polyurethane that penetrates deep into concrete to make permanent repairs. Nearly thin as water at less than 9cps, Concrete Mender™ actually injects itself into the matrix of the concrete and shores up the existing concrete as well as making the repair. Concrete Mender™ eliminates the bond line as it Microdowels into the concrete. We call it Microdowling™. |
![]() Permanent repair in just 10 minutes. Concrete Mender™ cures quickly to a durable 4500psi polymer concrete that effectively transfers heavy loads throughout the repaired area, eliminating pop-outs. |
![]() Cures in just 10 minutes at 70°F (21°C) • Works in freezers below -20°F (-28°C) • May be polished • Never gets brittle • Easily applied • Contains no epoxy or polyurea • Easy to mix • Nonflammable • Low V.O.C’s • Paintable • Coatable • Sandable • Meets USDA guidelines • And more… |
![]() Self-mixing at point of application. |
![]() Needle tip mixes are available. |
![]() Full-depth crack injection is possible without pumps or ports. The easy-to-use soft-tip injection mixers make this process efficient. |
![]() Bulk mix application for larger cracks and spalls is available in one-gallon containers in two-gallon kits. Simply add sand and mix by hand. Ten-gallon kits are also available. |
![]() To extend with sand, mix one gallon of Concrete Mender™ with 2 parts silica sand to create approximately 2.2 gallons of repair material. This yields twice the amount compared to epoxy or polyurea. Please refer to our Product Estimator for more details. |
![]() Freezer Floors |
![]() Grind, polish, and coat. Accepts polishing or most coating systems in about 10 minutes at 70°F (21°C) |

“The key lies in the surface tension,” says Kelton Glewwe, the Vice President of Marketing. “With a surface tension that is just one-third that of water, Concrete Mender penetrates deeply into concrete surfaces, effectively anchoring itself within millions of micro fractures in cracked concrete. We refer to this innovative process as Microdoweling™, a unique feature exclusive to Concrete Mender™. This remarkable phenomenon can be observed using an electron microscope. For further details, a comprehensive report is available on the Roadware website.”Top experts in the concrete industry agree and recommend Roadware 10 Minute Concrete Mender™ for repairs at major retailers such as Wal-Mart, Home Depot, Lowe’s, Menards, Target, Honda, Boeing, Costco, Best Buy, and many others. “Wherever durability and reliability are crucial for floors, industry experts trust Roadware 10 Minute Concrete Mender™.”

Roadware 10 Minute Concrete Mender™ has a proven track record of repairing shrinkage cracks and spalls in elevated structures such as parking decks, bridges, and airport terminals. Concrete Mender™ is recognized as a structural polyurethane and can be applied where the surrounding concrete is stable.
Structural Polyurethane – This polyurethane-based material is specifically formulated to restore the structural integrity and aggregate interlock of distressed concrete. It achieves this by utilizing low surface tension and low viscosity, allowing it to effectively penetrate concrete surfaces. The polymer chains in this material cross-link and bond directly with the concrete-aggregate matrix. This bonding process takes advantage of capillary forces to help self-inject polymer chains into the surrounding concrete.The structural polyurethane should have a modulus of elasticity that is lower than that of the surrounding concrete and should not become brittle over time. Additionally, this material can be combined with manufactured sand to create a polymer concrete that is compatible with Portland Cement Concrete (PCC). This combination can be used for structurally repairing concrete cracks and spalls.
Advantages – Due to the very low surface tension and low viscosity of the material, complete saturation bonding of cracks can be easily achieved. Minimal preparation, such as removing loose debris, is usually all that is required. This can be considered a structural repair if the material is allowed to gravity flow to the full depth of the crack. Manufactured sand or quartz may be introduced into the repair as necessary to prevent under-slab bonding and material waste. For repairs greater than 0.125 inches, specified sand may be added at a ratio of two parts sand to one part mixed polyurethane as the crack is filled to extend the material and enhance strength. The sand also helps align the thermal coefficient of expansion of the repair material with that of the surrounding concrete. Polyurethanes of this nature can be applied across a wide range of substrate temperatures, making them beneficial for frozen and cold storage warehouse applications or cold weather settings below -20F (-23C). Repairs are typically ready to accept traffic in about 10 minutes at 72F (22C).
Limitations – The surrounding concrete must be surface dry and cured for at least 60 days. Finished repairs may “yellow” in appearance over time when exposed to UV sunlight. In outdoor conditions, only low to non-movement cracks should be repaired.
“Roadware Easy Injection and needle tip crack injection costs less to install and is more effective than pressure applied epoxy injection methods.” according to top concrete repair contractors. “We can get in, permanently repair the cracks, and get out in the same time it use to take just to install the old injection ports.”
