After repairing, a topping layer has been added with 6cm of thickness and 12kg/m3 of Dramix 3D steel fibre. The concrete is also mixed with crystalline admix to reduce concrete permeability. The concept is quite interesting. Dramix fibre helps to limit crack width of the topping, while the crystalline admixture assists with pore blocking and self-healing the micro crack by nano crystals. Both products work very well together to offer to a offer the best solution.
