Hydraulic mortar by resistance or dosing. It is able to flow and cover any part or corner of the surface to be levelled, just due to its own weight, without creating segregation. Its manufacturing process includes cements, fine silica or calcareous sand centered in a established zone, specific additives and water.
The transport to the site is done on a concrete mixer truck, the placement of the material is done using a pumping system and it is applied by specialised personnel.
