Fosroc Patchroc RSP


Patchroc RSP is a blend of dry powders and graded aggregates which requires only the site addition of clean water to produce a highly consistent, high strength, free-flowing repair concrete which self-compacts. The material is a blend of inorganic cements, special fillers and chemical additives to control the rate of strength gain to provide a fluid micro-concrete with good handling characteristics, Patchroc RSP exhibits excellent thermal compatibility with concrete and good water repellent properties.
