Fosroc HB40+

Key Points

• High-build shrinkage-compensated repair mortar
• Suitable for vertical and overhead repairs
• Low permeability for durability
• Ideal for large structural reinstatement works

Fosroc Renderoc HB40 Plus is a high-build, shrinkage-compensated repair mortar for reinstating damaged reinforced concrete.
It is designed for vertical and overhead concrete repairs where strength, durability, and build thickness matter. HB40 Plus is suitable for patch repairs to walls, beams, columns, soffits, precast panels, car parks, civil structures, and other areas where damaged or spalled concrete needs to be rebuilt with confidence.
The high-build formulation allows larger repairs to be completed with fewer applications, while the shrinkage-compensated design helps maintain dimensional stability as the repair cures. HB40 Plus also offers low permeability to water, carbon dioxide, and chloride ions, making it a strong option for exposed or aggressive environments where long-term durability is important.
