Microbially induced corrosion resistant SEWER REPAIR MORTAR.

Sika MonoTop-4400 MIC is a 1-part, ready to use, high performance, calcium aluminate mortar specifically designed for the repair and protection of new or existing sewer infrastructure from biogenic sulphuric acid corrosion.

  • Resistant to biogenic sulphuric acid corrosion
  • Resistant to pure water, salt water, sulphated soils and several diluted acids
  • Does not contain chlorides or other corrosion promoting additives
  • Suitable for machine application (wet and dry spray technique)
  • High bond strength
  • High early compressive strength, class R4 of EN 1504-3
  • Fast return to service (within 1 hour if Sikagard-230 MIC surface hardener is used)
Usage
Particularly suitable for the protection and refurbishment of:
  • Sewer infrastructure
  • Manholes
  • Lift stations, pumping stations
  • Main trunk sewers, collectors
  • Sewer pipes
  • Waste water treatment plants
Suitable for repair work (Principle 3 concrete restoration, method 3.1 & 3.3; Principle 4 structural strengthening, method 4,4 of EN
1504-9) in sewer and waste water treament plant. Suitable for concrete protection (principle 2 moisture control, method 2.2; Principle
8 increase resistivity, method 8,2 & Principle 5 physical resistance, method 5,1).
