FOSROC Renderoc HB70 | WPD Group

For the reinstatement of localised patch repairs and larger areas of reinforced concrete. Renderoc HB70 is alkaline in nature and will protect embedded steel reinforcement. It is specifically designed for locations where high compressive strengths are required or in locations where good abrasion resistance is necessary. The mortar is suitable where resistance is required to chlorides and carbon dioxide. Where compatibility with lower strength concrete is required, Renderoc HB25 or Renderoc HB40 should be considered. Renderoc HB70 is suitable for use with Galvashield anode protection and Cathodic Protection systems. Contact Fosroc for further details.
