Description

A flexible, foaming, two-part injection resin for sealing cracks in concrete or masonry in wet conditions to form a slightly elastic seal. It has good adhesion to concrete and masonry and when injected into cracks it allows some movement without loss of bond.

Advantages:

  • Low viscosity enables it to penetrate fine cracks and cavities.
  • Reacts with water and forms flexible closed cells. that allow the movement of the crack.
  • Flexible to withstand differential movement.
  • Free expansion: 800%.
  • Chemically resistant to water, weak acids, alkali and micro-organisms.
  • Excellent adhesion to mineral construction materials (such as concrete, cement, brick and mortar) and metal.
  • Reaction speed is controlled by varying the amount of hardener: 6-9% hardener achieves a good cell structure.
