Description
Renderoc HB30 high performance, fibre reinforced, lightweight mortar (R3) has been specifically engineered for vertical and overhead repair work. It can be applied in sections up to 85 mm thickness in vertical locations and up to 75 mm thickness in overhead locations in a single application and without the use of formwork.
Thicker sections can be achieved by the use of formwork or can be built up in layers. Deep pockets can sometimes be filled in a single application dependent on the configuration of the pocket and the volume of exposed reinforcing steel. Renderoc HB30 can be quickly and efficiently applied by the wet spray technique.
Key Features
- Maximum compatibility with concrete of compressive strength 20 - 35N/mm²
- Lightweight formulation enables extra high-build — fewer cold joints
- Frequently obviates the need for formwork
- Polymer-modification provides extremely low permeability to water, carbon dioxide and chlorides
- Exceptional system of shrinkage compensation provides long-term dimensional stability
- Can be applied quickly and efficiently by wet spraying
- One component, pre-bagged to overcome site-batched variations
- Contains no chloride admixtures
