    Repair Mortars and Dry Mixes

    This range is for repairing damaged concrete and for small jobs where batching on site is not practical. It includes a pre-packed concrete repair mortar for columns, beams and slabs, a polymer liquid for site-batched mortar, and an SBR latex that works as a bonding agent, mortar modifier and waterproofing slurry. The repair mortars and dry mixes also include ready mix plaster and ready mix concrete in dry powder form, where you just add water. Use the chooser below to pick the right product for your repair.

    ROOFCRETE AR

    ROOFCRETE AR is a two-component, pre-packed, high-build polymer-modified structural reinstatement mortar. Part 1 (polymer liquid) is mixed with Part 2 (fibre-reinforced powder) at the exact factory-set ratio — no site batching, no dosage errors. Achieves 13 N/mm² compressive strength at 1 day, 48 N/mm² at 28 days and 9 N/mm² flexural strength. NIL chloride, NIL carbonation and 0.40% water absorption make it fully reinforcement-safe. For structural repair depths of 6–100 mm on columns, beams, slabs and spalled concrete.
