Patchwell Deep is a high quality, single-component, polymer modified mortar specifically designed for repairs to concrete where the depth of repair is between ¼" and 2” without the need for the addition of pea gravel. Patchwell Deep consists of special cements, dry latex polymers, and non-shrink additives that allow it to be used at greater thicknesses than most patching materials without shrinkage. For greater thicknesses the addition of pea gravel is recommended. This product is self-curing and provides better adhesion than standard mortars. The coefficient of thermal expansion is similar to that of normal concrete, ensuring thermal compatibility. Patchwell Deep contains a migrating corrosion inhibiting agent to protect embedded steel reinforcement from chloride and carbon dioxide penetration. Patchwell is specifically engineered for increased resistance to calcium chloride & deicing chemicals, as well as for increased resistance to freeze-thaw cycling.
