Description and properties

Dry mineral mix including a cement-based binder and enriching aggregates. It is used It contains aggregate of max. grain size 8 mm. It is also produces in the SPCC version. The INCRETE FK4 mix is used for thin-layer concrete spraying of layer thickness at least 25 mm or as the last finishing layer. Maximum thickness of one layer must not exceed 30 mm.

Recommended use

  • to produce shotcrete by means of a dry method for repairs and filling defects on large surfaces of engineering structures, i.e. bridges, flyovers, tunnels, retaining walls, weirs, water thresholds, dams, breakwaters, watersides. It is also used to reinforce excavation embankments.
  • can be used on properly prepared damp concrete (matt-damp) - at substrate temperatures and the air
    from + 5 ° C to + 35 ° C,
