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. 

Description

Sika MonoTop®-4052 is a one-part, cementitious, fibre-reinforced concrete repair mortar and screed, meeting the requirements of Class R4 of EN 1504-3.


Features and benefits:

  • Uses recycled raw materials.
  • Compatible with cathodic protection systems.
  • High abrasion resistance.
  • Low drying shrinkage and very low sensitivity to cracking (can be applied up to 300 m² without joints).
  • Sulphate-resistant.
  • Suitable for internal and external applications.
  • Easy to apply.
  • Good resistance to sea water.
  • Dust-reduced for a cleaner, healthier environment.
