Product Description

Fosroc® Renderoc HB is a high performance lightweight concrete reinstatement mortar conforming to to the requirements of BS EN 1504-3 Class R2.

Best Uses

Fosroc Renderoc HB is used for the reinstatement of concrete where low permeability characteristics are required but where high compressive strength is not the most important consideration. If high compressive strengths and low permeability characteristics are required, Renderoc HB45 should be used.

Renderoc HB has been specifically developed for vertical and overhead repair work where its lightweight nature and high build characteristics makes it ideal.
Renderoc HB is suitable for repair methods 3.1, 3.3, 7.1, 7.2 as defined by BS EN 1504-3.

Renderoc HB is supplied as a ready to use blend of dry powders requiring only the site addition of clean water to produce a highly consistent, lightweight repair mortar. It is based on Portland cements, graded aggregates, lightweight fillers and chemical additives which provide a mortar with good handling characteristics while minimising water demand.

Application

The low water requirement ensures good strength gain and long-term durability. Renderoc HB has been specifically engineered for vertical and overhead repair work. It can be applied in sections up to 100mm thickness in vertical locations and up to 60 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 HB can be quickly and efficiently applied by the wet spray technique. Consult our Technical Team for more information.

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