Cement-based R4 class structural repair mortar is a high-performance repair material specially formulated for the repair of structural damages. This mortar offers a reliable solution for repairing cracks, cavities, and other structural damages in reinforced concrete load-bearing systems. Thanks to its high adhesion strength, low water absorption, and fast curing time, it forms a durable and waterproof repair layer in a short time. The R4 repair mortar also stands out with its combination of high strength and flexibility, providing long-lasting protection to the structure. Thus, the lifespan of structures is extended while maintenance costs are reduced. It is especially preferred in earthquake zones and structures subjected to heavy loads, making it an ideal solution to enhance structural safety.
