Renderoc HBS 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 and chemical additives which provide a mortar with good handling characteristics while minimising water demand. The low water requirement ensures good strength gain and long-term durability.
It can be applied in sections up to 60mm thickness in vertical locations and up to 50mm thickness in overhead locations in a single application 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.
The material should not be applied at less than 10mm thickness.
For the compatible reinstatement of defects in high strength reinforced concrete structures.
Renderoc HBS is particularly suited to the repair of vertical surfaces and, because of its relatively low fresh wet density, can also be used for overhead repairs.
Renderoc HBS is suitable for repair methods 3.1, 4.4, 7.1, 7.2 as defined by BS EN 1504-3.
