Features/Benefits

Advantages– Due to the very low surface tension of the material and low viscosity, complete saturation bonding of cracks can be easily achieved. Minimal prep to remove loose debris is all that is normally 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 ponding and material waste. 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. The sand also brings the thermal coefficient of expansion of the repair material closer in-line with surrounding concrete. 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). Repairs are typically ready to accept traffic in approximately 10 minutes at 72F (22C)

Technical Information

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. This bonding action utilizes capillary forces to self-inject polymer chains into the surrounding concrete. This material should have a modulus of elasticity less than the surrounding concrete and should not become brittle over time. This material may be combined with manufactured sand to form a PCC compatible polymer concrete that can structurally repair concrete cracks and spalls.
