Concrete Repair

The choice depends on whether the repair is structural or cosmetic, the thickness being built up in one pass, and whether the mortar is applied by hand or sprayed. Each product's data sheet states its compressive strength class, maximum layer thickness and application method. Send us the defect type and depth and we will narrow it to the right product.

Where reinforcement has corroded, a reinforcement protection and bonding coat is normally specified before the repair mortar goes on. Note also a well-documented effect worth raising with your consultant: fresh alkaline mortar re-passivates the steel inside the patch, which can shift the electrochemical balance and start new corrosion in the surrounding older concrete. This is called the incipient anode or halo effect, and on chloride-contaminated structures it is why a specification may call for additional measures beyond the patch itself. We supply SikaTop Armatec 110 EpoCem and Sika MonoTop 610 for the protection and bonding step.

Yes. Each data sheet publishes a consumption figure, usually in kilograms per square metre per millimetre of thickness. Send us the repair area and average depth and we will estimate the quantity and pack count using the manufacturer's published rates.
