For the reinstatement of areas of concrete where low permeability characteristics, lowest drying shrinkage characteristics is required. Renderoc HB25 has been specifically engineered for vertical and overhead repair work where its lightweight nature makes it ideal. The mortar can also be used for small, localised patch repairs.
Where higher compressive strengths are required as well as low permeability characteristics, Renderoc HB40, Renderoc HB70 or Renderoc LA55 should be used.
