Sika MonoTop®-4012 - Concrete Repair Mortar
Verified by manufacturer 5 months ago
High performing more sustainable R4 concrete repair mortar.
Application
Sika MonoTop®-4012 is used 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.
