Description
Renderoc LA55 is a high-strength, free-flowing micro-concrete designed for form-and-pour repairs up to 200 mm thick. Meeting EN 1504-3 Class R4, it restores structural integrity while its dense, low-permeability matrix pairs perfectly with Galvashield® embedded anodes for long-term corrosion protection.
Features + Benefits:
Class R4 Structural Strength: Achieves >45 MPa compressive strength for load-bearing reinstatement. Free-Flowing Consistency: Self-compacting mix pours or pumps easily into congested formwork without segregation. Thick-Section Capability: Single-lift placement up to 200 mm cuts labour time and cold-joint risk. Shrinkage-Compensated: Volume-stable formulation minimises cracking and ensures full contact with host concrete. Low Permeability & High Resistivity: Blocks water, chlorides, and CO₂ to safeguard embedded steel. Anode-Compatible: Formulated for seamless use with Galvashield galvanic corrosion-protection systems.
Product Uses:
Form-and-pour reinstatement of deteriorated columns, beams, bridge piers, and deck soffits;
Encasement or jacketing of structural members where increased cover or section enlargement is required;
Deep-void repairs around embedded galvanic anodes in marine, industrial, or transport infrastructure.
Pack Size:
Supplied in 25 kg moisture-resistant bags—each bag yields approximately 12–13 L of mixed micro-concrete (coverage ≈0.013 m³).
