Renderoc® HB40 Plus
High strength - suitable for structural repairs
Abrasion resistant - suitable for aggressive environments
Renderoc® HB40 Plus, a medium weight concrete repair mortar, 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, repair mortar. The material is based on the latest advances in cement, fillers and chemical additives technology and is polymer modified to provide a mortar with good handling characteristics, while minimising water demand. The low water requirement ensures fast strength gain and long-term durability.
