Verified by manufacturer 3 months ago
R4, one-part, cementitious, fibre-reinforced concrete repair mortar and screed.
Application
Used to repair all types of reinforced concrete structures and components for:
- Buildings.
- Car park decks.
- Civil engineering structures.
- Dams and bridges.
- Marine structures.
Used for:
- Restoration work (Principle 3, method 3.1 and 3.3 of EN 1504-9). Repair of spalling and damaged concrete in infrastructure and superstructure works.
- Structural strengthening (Principle 4, method 4.4 of EN 1504-9). Increasing the bearing capacity of the concrete structure by adding mortar.
- Preserving or restoring passivity (Principle 7, method 7.1 and 7.2 of EN 1504-9). Increasing cover with additional mortar and replacing contaminated or carbonated concrete.
