Sika MonoTop®-4012 - Class R4 Concrete Repair Mortar
Verified by manufacturer 6 days ago
High-performance, more sustainable, Class R4 concrete repair mortar.
Application
For use to repair all types of reinforced concrete structures and components for:
- Buildings.
- Civil engineering structures.
- Dams.
- Marine structures.
- Suitable for interior or exterior applications.
- Sewage and waste water treatment plants.
The product is 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.
