Key Features

  • Reactive Bonding
    Forms strong molecular-level bonds with concrete and plaster surfaces.
  • Monolithic Joints
    Ensures a seamless and flexible connection between structures.
  • Highly Water-Resistant
    Protects against seepage and leakage in bonded areas.
  • Exceptional Adhesion Strength
    Offers a pull-off strength of 1.7 N/mm² for secure and durable joints.
  • Flexible Polymeric Film
    Adapts to thermal cycling and shrinkage stresses, reducing the risk of cracks.

Challenges Addressed

  • Weak Joints

    Old and new concrete parts often create weak interfaces prone to water migration and structural failure.

    Weak Joints

  • Thermal Cycling Cracks

    PCC and RCC sections cast in parts develop cracks due to thermal expansion and contraction.

    Thermal Cycling Cracks

  • Seepage Issues

    Junctions between concrete and masonry walls are susceptible to water seepage and leakage over time.
