Fosroc Renderoc RS Xtra is a polymer‑modified, rapid‑setting repair concrete supplied as a dry powder that is mixed on site with clean water to form a free‑flowing, self‑compacting mix. It is intended for emergency reinstatement of damaged concrete both internally and externally, including high‑traffic areas such as airport runways where fast return to service is required. The system provides shrinkage control, good thermal compatibility with existing concrete and water‑repellent properties.
