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.

Description

Sika MonoTop®-4012 is a one-part, cementitious, fibre reinforced, low shrinkage repair mortar. It contains recycled raw materials and can reduce the carbon footprint application activity calculations.


Features and benefits:

  • Uses recycled raw materials.
  • Layer thickness 6–120 mm.
  • Sulphate resistant.
  • Hand and machine application (wet spray technique).
  • Easy to apply.
  • Very low shrinkage.
  • Dust reduced.
  • Good resistance to sea water.
  • Does not require a bonding primer.
  • Low permeability.
  • Euroclass A1 fire rating.
  • Class R4 of EN 1504-3.
  • Resistant to sulfuric acid attack (exposure classes
