    Key Benefits

    • BDA Agrément for proven performance.
    • Pre-packaged materials easily mixed on site.
    • Tough, flexible coating which maintains its elastomeric properties even under immersed conditions to accommodate movement in cracks.
    • Excellent adhesion to sound prepared concrete and masonry substrates, as well as steel.
    • Dense matrix offers low permeability to water and carbon dioxide gas.
    • A 2mm coat provides the equivalent to 135mm of good quality concrete cover.
    • Can be applied to damp substrates in temperatures down to 5°C.
    • Water-based product. Non-toxic when cured.

    Typical Applications

    Typical Applications

    Waterproofing of:
