Renderoc HB High-Build Concrete Repair Mortar – Perth
Renderoc HB High-Build Concrete Repair Mortar – Perth
Renderoc HB is a lightweight, high-build concrete repair mortar developed for localised vertical and overhead patch repairs. Its lightweight formulation helps contractors build thicker repairs with reduced slump and less dependence on formwork, making it useful on columns, beams, soffits and other difficult-to-access concrete surfaces.
Fosroc positions Renderoc HB for repairing concrete with compressive strength up to 25 MPa. Current published information lists a vertical trowel build depth of 10–80 mm and a 28-day compressive strength of 28 MPa. The pre-bagged, shrinkage-compensated mortar can be applied by trowel or wet spray and provides low permeability together with resistance to water, carbon dioxide and chloride ions.
Before application, deteriorated or contaminated concrete should be removed and the remaining substrate prepared to provide a clean, sound surface and suitable mechanical key. Any exposed reinforcement must be assessed and treated as required. Application thickness, mixing water, priming, curing and environmental limits should follow the latest Fosroc Technical Data Sheet. For higher-strength substrates or repairs outside the stated build range, another Renderoc grade may be more appropriate.
