High-strength, shrinkage compensated, fibre reinforced, structural repair mortar.

Emaco Nanocrete R4 is a single component, extra highstrength, high modulus, shrinkage compensated structural repair mortar that meets the requirements of the new European Norm EN 1504 part 3 class R4. Emaco Nanocrete R4 is a ready-to-use material that contains Portland cement, well graded sands, specially selected polymer fibres and special additives to significantly reduce the risk and incidence of shrinkage cracking. When mixed with water, it forms a highly thixotropic mortar that can easily be spray or trowel applied.

Emaco Nanocrete R4 is used for the structural repair of concrete elements such as:

Columns, piers and cross beams of all bridges
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
