    • SikaEmaco® S 5400 (formerly known as MasterEmaco® S 5400) (Emaco Nanocrete R4) - structural repair mortar

    SikaEmaco® S 5400 (formerly known as 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.
