MasterEmaco S 5400 – Extra high-strength, shrinkage compensated, fibre reinforced, thixotropic structural repair mortar

Formerly: Emaco Nanocrete R4

What is and where to use MasterEmaco S 5400?

MasterEmacoS5400 is a thixotropic lightweight high build repair mortar with medium strength from5 up to 60 mm thickness, class R4. It is a ready-to-use material to be hand, trowel or spray applied on horizontal, vertical and overhead areas. When mixed with water it forms a mortar with an exceptional wide range of applications.


MasterEmaco S 5400 is used for the structural repair of concrete elements such as:

  • Columns, piers and cross beams of all bridges
  • In conjunction with electro-chemical cathodic protection systems
  • Cooling towers and chimneys and other industrial environments
  • Water treatment and sewerage facilities
  • Tunnels, pipes, outfalls and all below ground construction especially in harsh ground conditions
  • Marine structures

Why MasterEmaco S 5400 is the most efficient solution for structural repair?


MasterEmaco S 5400 provides a durable, strong structural repair fully compatible with host concrete.


How you will enjoy the benefits of MasterEmaco S 5400?

MasterEmaco S 5400 is a ready-to-use material that contains Portland cement, hydraulic binders, well graded sands, specially selected polymer fibres (PAN – polyacrylonitryl) and special additives to significantly reduce the risk and incidence of shrinkage cracking.

When mixed with water, MasterEmaco S 5400 forms a highly thixotropic mortar that can easily be spray or trowel applied.

  • Can be applied inside and outside, on vertical and overhead surfaces, in dry and wet environments.
  • Formulated with new nanotechnology, shrinkage compensation systems and fibre reinforcement (polyacrylonitryl fibres) to minimize crack tendency.
  • Highly thixotropic - can be applied up to 50 mm without the need of secondary reinforcement.
  • High early and ultimate strengths.
  • Outstanding workability for easy placing and finishing.
  • High modulus and excellent adhesion to host concrete ensuring load transfer.
  • Excellent freeze/thaw resistance.
  • High carbonation resistance.
  • Very low permeability to water and chlorides.
  • Low chromate (Cr [VI] < 2 ppm).
  • Does not contain chlorides.
