Masonry Repair Mortars

Masonry repair mortars are used to fair, rebuild and reinstate damaged cement-based masonry and concrete where a standard site-mixed mortar does not provide the required bond, build or shrinkage control. This range is deliberately limited to RLA Penapatch mortars with manufacturer-supported adhesion to concrete and masonry substrates.

Choose by repair depth and structural requirement

• Thin fairing and finishing: RLA Penapatch Fairing Coat Mortar fills surface imperfections and produces a smooth finish in applications up to 5mm.
• High-build structural repair: Penapatch HB50 provides medium-weight reinstatement for vertical, overhead and horizontal repairs where a higher-build mortar is required.
• Higher-strength structural repair: Penapatch HB80 suits heavier-duty repairs where high compressive strength, abrasion resistance and low permeability are required.
• Lightweight non-structural repair: Penapatch Panel LW is designed for precast and tilt-up patching, including cover over joining plates, where a lightweight high-build mortar is preferred.

Masonry compatibility does not make every repair identical

These mortars are suitable for compatible concrete and masonry substrates, but selection still depends on repair depth, substrate condition, exposure, reinforcement and whether the repair is structural. Historic brickwork, moving cracks, active leaks and ordinary repointing may require a different repair method or mortar system.
