Structural Reintegration of Reinforced Concrete Columns and Beams
Repair 450 system: structural concrete repair for columns and beams with reinforcement passivation and fine finish coat
Layer-by-layer system specification
This three-product system covers the structural reintegration of reinforced concrete columns and beams, from passivation of exposed reinforcement bars through high-build structural repair mortar to fine finish levelling coat. Repair 450 is the high-build repair mortar in the Licata range, suited to significant section loss on structural elements.

Structural concrete repair with a Class R4 mortar
The Repair 450 system is a complete, EN 1504 concrete repair specification for the structural reintegration of reinforced concrete columns and beams. At its core is Repair 450, a thixotropic, structural, fibre-reinforced polymer-modified cement mortar, class R4 in accordance with UNI EN 1504-3, with controlled hygrometric shrinkage, designed for the restoration and skim coating of concrete at thicknesses between 5 and 50mm.
Repair 450 was formulated to ensure the best performance levels in restoration and restructuring work on the most commonly used cement substrates in construction. It can be laid in variable thicknesses of between 5 and 50mm by hand or by machine, efficiently accommodating all the application requirements of construction sites. The full system pairs it with reinforcement passivation and a fine finishing coat for a durable, compliant structural repair.
What is a Class R4 repair mortar?
EN 1504-3 classifies concrete repair mortars by compressive strength and structural capability. R1 and R2 are non-structural; R3 and R4 are structural, with R4 the highest class and greatest compressive strength, suited to load-bearing repairs where the mortar performs as part of the structure.
Because Repair 450 is fibre reinforced with controlled hygrometric shrinkage, it resists the cracking and de-bonding that can affect lesser repair mortars, producing a durable, monolithic repair that bonds reliably to the parent concrete.

View productWhy specify the Repair 450 system?
Class R4 Structural
The highest structural classification under UNI EN 1504-3, for load-bearing repairs to columns, beams and structural concrete.
Fibre Reinforced
Fibre reinforcement improves tensile performance and crack resistance for a tougher, more durable repair.
Controlled Shrinkage
Controlled hygrometric shrinkage minimises shrinkage cracking and de-bonding as the mortar cures.
Thixotropic
Vertical and overhead application without slump, ideal for columns, beams and soffits.
5 to 50mm Build
Variable thickness from 5 to 50mm, covering both skim coating and significant section restoration.
Hand or Machine
Applied by hand or machine spray, efficiently meeting the pace of live construction sites.
