Application

For the reinstatement of reinforced concrete where low permeability characteristics are required and where higher compressive strength is a consideration.

Renderoc HB45 has been specifically developed for the repair of columns and beams, but because of its medium fresh wet density, is also suitable for soffit repairs.

Renderoc HB45 is suitable for repair methods 3.1, 3.3, 4.4, 7.1, 7.2 as defined by BS EN 1504-3.

Description

Renderoc HB45 is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a highly consistent, medium-weight repair mortar.

It is based on Portland cements, graded aggregates, lightweight fillers, fibres and chemical additives which provide the mortar with good handling and finishing characteristics while minimizing water demand. The low water requirement ensures good strength gain and long-term durability.

Renderoc HB45 has been specifically engineered for vertical and overhead repair work. It can be applied in sections up to 80 mm thickness in vertical locations and up to 70 mm thickness in overhead locations in a single application without 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 HB45 can be quickly and efficiently applied by the wet spray technique. Consult the local Fosroc office for further information.

  • The material should not be applied at less than 10 mm thickness.

Recyclability

At the end of its service life, the product is embedded within the concrete structure subject to repair. The demolition process comprises the structure being mechanically broken apart, with concrete transported off site for reprocessing. Typically 80% by mass reused as inert aggregate; 20% disposal to inert landfill.
