Concrete Repair 

Concrete repair mortars are specialized materials used to restore damage and deterioration in concrete structures, reinstating their strength, stability, and appearance. According to the EN 1504-3 standard, they are classified into categories R1 to R4, depending on their strength and intended application: R1–R2: suitable for non-structural and surface repairs, and R3–R4: designed for structural restorations requiring high mechanical strength and long-term durability.
