Fosroc Renderoc HB40 Plus

Renderoc HB40 Plus is an extra-high-build, shrinkage-compensated repair mortar that trowels up to 40 mm per layer on vertical or overhead concrete. Engineered to EN 1504-3 Class R3 and compatible with 25–50 MPa substrates, it delivers low-permeability, high-resistivity repairs that safeguard steel reinforcement in aggressive environments.

Features + Benefits:

Extra-High Build: Applies up to 40 mm in a single pass—cuts labour and accelerates programme.
Shrinkage-Compensated Matrix: Maintains full contact with the host concrete to minimise cracking and debonding.
Low Permeability & High Resistivity: Blocks water, chlorides, CO₂, and other corrosive agents for long-term durability.
EN 1504-3 Class R3 Compliance: Provides structural-grade strength compatible with concrete 25–50 MPa.
Ready-to-Use Powder: Single-component formulation—just add water for consistent site mixing and reduced waste.

Product Uses:

Reinstating spalled or carbonated concrete on columns, beams, decks, and soffits;
Vertical and overhead repairs where thick, volume-stable builds are essential;
Infrastructure, marine, industrial, and transport structures requiring low-permeability patch repairs.

Pack Size:

Supplied in moisture-resistant 25 kg bags—yielding approximately 13 L of mixed mortar (coverage ≈1 m² at 13 mm thickness).
