FOSROC Renderoc HB | WPD Group

For the reinstatement of large areas of concrete and for small, localised patch repairs. Renderoc HB is alkaline in nature and will protect embedded steel reinforcement. It is specifically designed for vertical and overhead high-build applications. The mortar is suitable where medium strength, as well as exceptional chloride and carbon dioxide resistance is required.


  • Lightweight formulation enabling extra high-build and thereby saving time and expense of multiple applications
  • Reduces the need for formwork
  • Can be applied by the wet spray process for fast, exceptionally high-build repairs with enhanced strength
  • Extremely low permeability provides maximum protection against carbon dioxide and chlorides
  • Excellent bond to the concrete substrates
  • Shrinkage compensated
  • Pre-bagged to overcome site-batched variations - only the site addition of clean water required
  • Contains no chloride admixtures
