Make repairs that last — in minutes, not hours.
Roadware 10 Minute Concrete Mender™ is the industry’s most advanced Microdoweling™ structural polyurethane, engineered to penetrate deep into concrete and create permanent, high‑strength repairs. Nearly as thin as water, it flows into microfractures, bonds internally with the slab, and never becomes brittle — delivering repairs trusted by major retailers, warehouses, factories, and distribution centers worldwide.
Why Concrete Mender™ is Different
Deep‑penetrating Microdoweling™ Technology
Concrete Mender™ doesn’t sit on the surface — it injects itself into the concrete matrix, eliminating the traditional bond line. With a viscosity under 9cps and surface tension one‑third that of water, it anchors into millions of microfractures for unmatched durability.
Permanent Repairs in Just 10 Minutes
Once mixed, Concrete Mender™ cures to a 4500 psi polymer concrete that transfers heavy loads and resists pop‑outs, impact, and industrial traffic. Floors can return to service in about 10 minutes at 70°F (21°C).
Works Where Other Products Fail
- Performs in freezers below -20°F (-28°C)
- Never becomes brittle
- Accepts grinding, polishing, and coatings in minutes
- Compatible with manufactured sand for structural repairs
- Meets USDA guidelines
Key Advantages
- Cures in 10 minutes at 70°F (21°C)
- Works in extreme cold
- Non‑brittle structural polyurethane
- Easy to mix and apply
- Low VOC, nonflammable
- Paintable, coatable, sandable
- No epoxy or polyurea
- Minimal prep required
Application Options
Cartridge Application
Use standard 1:1 ratio 600ml cartridges for self‑mixing at the point of application. Ideal for fast crack and spall repair.
Needle Tip Injection
Available in 14, 15, and 18 gauge for precise crack injection. Full‑depth crack repair is possible without pumps or ports.
Bulk Mix for Larger Repairs
Available in one‑gallon and ten‑gallon kits. Simply add sand and mix by hand for large spalls, wide cracks, and structural restoration.
Pump with Precision
Purpose-built pump available for large projects and applications.
Extend with Sand for More Material
Mix one gallon of Concrete Mender™ with two parts silica sand to produce approximately 2.2 gallons of polymer concrete — doubling yield compared to epoxy or polyurea. See the Product Estimator for detailed calculations.
Performance in Demanding Environments
Freezer Floors
Concrete Mender™ performs reliably in working freezers below -20°F (-28°C), making it ideal for cold storage warehouses.
Grind, Polish, Coat
Repairs accept polishing or most coating systems in about 10 minutes.
Structural Polyurethane for Industrial Repairs
Concrete Mender™ restores aggregate interlock and structural integrity in distressed concrete. Its low viscosity and low surface tension allow deep penetration, while manufactured sand creates a polymer concrete compatible with PCC.
Advantages
- Complete saturation bonding of cracks
- Minimal surface prep
- Gravity‑flow full‑depth crack repair
- Sand extension aligns thermal expansion with surrounding concrete
- Wide temperature application range
Limitations
- Surrounding concrete must be dry and at least 60 days cured
- Repairs may yellow with UV exposure
- Outdoor repairs should be limited to non‑moving cracks
Trusted by Industry Leaders
Top experts recommend Concrete Mender™ for major retailers and facilities including: Wal‑Mart, Home Depot, Lowe’s, Menards, Target, Honda, Boeing, Costco, Best Buy, and more.
“Concrete Mender penetrates deeply into concrete surfaces, anchoring itself within millions of microfractures. This innovative process — Microdoweling™ — is unique to Roadware.” — Kelton Glewwe, VP of Marketing
Faster, More Effective Crack Injection
Roadware Easy Injection and needle‑tip systems cost less and outperform pressure‑applied epoxy injection. Contractors report completing permanent repairs in the time it used to take just to install epoxy ports.

“The key lies in the surface tension,” says Kelton Glewwe, Vice President of Marketing. “With a surface tension just one-third that of water, Concrete Mender penetrates deeply into concrete surfaces, effectively anchoring itself within millions of microfractures in cracked concrete. We call this innovative process Microdoweling™, a unique feature exclusive to Concrete Mender™. This remarkable phenomenon can be observed with an electron microscope. For more 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 floors, walls, and 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 exploits capillary forces to help self-inject polymer chains into the surrounding concrete. The structural polyurethane should have a modulus of elasticity 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 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. Over time, finished repairs may develop a yellow appearance when exposed to UV sunlight. In outdoor conditions, only cracks with minimal to no movement 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.”
