FOSROC RENDEROC HB45 

Fosroc Renderoc HB45 is a high-performance, fiber-reinforced, medium-weight concrete reinstatement mortar packaged in 25 kg bags. Conforming to BS EN 1504-3 Class R4, it is designed for the reinstatement of reinforced concrete structures, providing low permeability and higher compressive strength. Suitable for repair methods 3.1, 3.3, 4.4, 7.1, and 7.2, it is ideal for columns, beams, and soffit repairs.

Key Features:

• Maximum compatibility with concrete of compressive strength 35 - 60 N/mm².
• High-build applications possible with higher compressive strengths, reducing cold joints.
• Polymer-modified for 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 for consistency and to overcome site-batched variations.
• Chloride-free formulation.

Applications:

• Renderoc HB45 is specifically engineered for vertical and overhead repair work, offering versatility in thickness and application methods. It can be applied in sections up to 40 mm thickness vertically and 30 mm overhead in a single application without formwork. Thicker sections can be achieved with the use of formwork or by building up in layers.
