Epoxy resin adhesives for repairing cracks, spalls and breaks in structural concrete and masonry
The repair and leveling adhesive is a paste-grade, modified epoxy system formulated for both surface sealing and structural repair. Designed for use on damaged or uneven concrete, it is ideal for patching cracks, spalls, and surface imperfections, as well as sealing joints or openings prior to injection grouting.
The adhesive has a putty-like consistency, offering high bond strength, excellent toughness, and abrasion, water, and chemical resistance. It adheres firmly to a wide range of substrates and provides a smooth, durable surface suitable for further structural treatment or finish work.

Applications
The repair & leveling adhesive is used to seal concrete surfaces prior to injection grouting, particularly in structural strengthening with bonded steel plates. It is also ideal for bonding and fixing injection ports, as well as sealing surface cracks during crack injection procedures to prevent adhesive leakage. It is suitable for repairing surface defects in concrete or masonry, including voids, spalls, and other irregularities, ensuring a smooth, structurally sound finish before final treatment.
