    FOSROC Renderoc HB 18kg

    Fosroc Renderoc HB in an 18kg package is a ready-to-use blend of dry powders, requiring only the addition of clean water on-site to create a lightweight repair mortar. Formulated with Portland cements, graded aggregates, lightweight fillers, and chemical additives, it ensures excellent handling characteristics while minimizing water demand. Specifically engineered for vertical and overhead repair work, Renderoc HB can be applied in sections up to 100mm thickness vertically and up to 60mm thickness overhead in a single application without formwork. Thicker sections can be achieved using formwork or built up in layers, providing flexibility in application.

    Key Features:

    • Compatibility with non-structural concrete of compressive strength 15 – 25 N/mm².
    • Lightweight formulation enables extra-high build, reducing cold joints.
    • Frequently eliminates the need for formwork.
    • Polymer-modification ensures extremely low permeability to water, carbon dioxide, and chlorides.
    • Exceptional shrinkage compensation for long-term dimensional stability.
    • Quick and efficient application by wet spraying.
    • One-component, pre-bagged to ensure consistency and overcome site-batched variations.
    • Chloride-free formulation.

    Applications:

    • Renderoc HB is ideal for the reinstatement of concrete where low permeability is crucial, and high compressive strength is not the primary consideration. It is specifically developed for vertical and overhead repair work, offering lightweight properties and high build characteristics. Suitable for repair methods 3.1, 3.3, 7.1, and 7.2 as defined by BS EN 1504-3.

    Advantages:

    • Renderoc HB provides compatibility with non-structural concrete, lightweight formulation for extra-high build, and efficient application methods, making it a versatile choice for various repair applications. Its polymer-modified composition ensures long-term durability and dimensional stability.
