Roadware 1006-STR Static Mixer 24 element with 3/8″ soft Easy-injection tip. #Concrete crack repair polyurethane injection gun install#“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.” Roadware 1006-15 Static Mixer 24 element with 15 gauge needle application tip. “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. In exterior conditions, only low to non-movement cracks should be repaired. Finished repairs may, “yellow” in appearance over time when exposed to UV sunlight. Limitations- The surrounding concrete must be surface dry, cured for at least 60 days. Repairs are typically ready to accept traffic in approximately 10 minutes at 72F (22C). Polyurethanes of this nature may be applied in a wide range to sub-straight temperatures making them useful in frozen and cold storage warehouse applications or cold weather application below -20F (-23C). The sand also brings the thermal coefficient of expansion of the repair material closer in-line with surrounding concrete. For repair 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 add strength. Manufactured sand or quartz may be introduced into the repair as necessary to prevent under slab ponding and material waste. #Concrete crack repair polyurethane injection gun full#This can be considered a structural repair if the material is allowed to gravity flow to the full depth of the crack. Minimal prep to remove loose debris is all that is normally required. This material may be combined with manufactured sand to form a PCC compatible polymer concrete that can structurally repair concrete cracks and spalls.Īdvantages– Due to the very low surface tension of the material and low viscosity, complete saturation bonding of cracks can be easily achieved. This material should have a modulus of elasticity less than the surrounding concrete and should not become brittle over time. This bonding action utilizes capillary forces to self-inject polymer chains into the surrounding concrete. Structural Polyurethane– A polyurethane based material that restores structural integrity and aggregate interlock to distressed concrete by using low surface tension and low viscosity to penetrate concrete surfaces and cross -linking polymer chains to bond directly to the concrete-aggregate matrix. Concrete Mender™ is considered a structural polyurethane and can be used where the surrounding concrete is stable. Roadware 10 Minute Concrete Mender™ has a strong history of repairing shrinkage cracks and spalls in elevated structures such as parking decks, bridges, and airport terminals. “Wherever people have to depend on their floor, the experts in the industry depend on Roadware 10 Minute Concrete Mender™.” We have the full report on the Roadware website.” Top experts in the concrete industry agree and recommend Roadware 10 Minute Concrete Mender™ for repairs in places like Wal-Mart, Home Depot, Lowes, Menards, Target, Honda, Boeing, Costco, Best Buy, and many more. We call the process Microdoweling™ and it only exists in Concrete Mender™ You can actually see it with an electron microscope. #Concrete crack repair polyurethane injection gun cracked#“With a surface tension one-third of water, Concrete Mender can slip deep down into the concrete surfaces and dowel itself into millions of micro fractures in the cracked concrete. “The key is the surface tension,” says Kelton Glewwe, Marketing Vice President. Roadware 10 Minute Concrete Mender double in volume with combined with two parts 4030 manufactured sand. Accepts polishing or most coating systems in about 10 minutes at 70☏ (21☌) Repair concrete at working freezer temperatures below -20☏ (-28☌). One gallon of Concrete Mender™ makes about 2.2 gallons of repair material when combined with 2 parts silica sand. Easy to use Sift-tip injection mixers make full depth crack injection possible.īulk mix application for larger cracks and spalls. Available in one gallon containers, two-gallon kits. Choose from 14, 15 or 18 gauge.įull depth crack injection without pumps or ports. See Cartridge Application Instructions.įor precise application. Use a standard 1:1 ratio 600ml cartridge application gun. In just minutes after application, Concrete Mender™ cures to a tough 4500psi polymer concrete that transfers heavy loads throughout the repair area. Concrete Mender™ eliminates the bond-line as it Microdowels into the concrete. 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. What makes Roadware 10 Minute Concrete Mender different from other concrete repair products? Roadware 10 Minute Conrcete Mender™ is a two-part polyurethane that penetrates deep into concrete to make permanent repairs.
