Repair and cladding industrial concrete floors, structural restoration, dimensional adjustments, increases in the resistant section, reconstruction of the thickness of the concrete removed by milling, etc.
The surfaces of application should be clean and free of any soiling, crumbling and non-adhering parts, dust, etc., saturated with water. In the case of surfaces to be rebuilt after milling, the areas of reconstruction will have to be in as regular a shape as possible (as similar to a square as possible); the thickness should be as homogeneous as possible; finally the section of the pre-existing flooring to be filled should be reminiscent of the shape of a trapezium which widens toward the bottom (this is in order to anchor the "patch" perfectly in the seat of reconstruction and to avoid its detachment, given the slightly expansive properties of the product).
It is necessary to provide a suitable bonding bridge between the part to be reconstructed and the reconstruction material. There are 2 alternative ways of doing this: - Roll out the specific epoxy primer on the prepared surface, using a roller or a brush, for structural construction joints Syntech RGS. - Prepare adequate additional reinforcement, parallel to the bottom of the reconstruction, consisting of electrowelded mesh (2 mm wire, 5x5 cm mesh) at a distance from the bottom of half the thickness, attached to the bottom itself by "L"-shaped steel bars, with improved adhesion and a diameter of 8 mm, inserted in holes and secured by expansive cement micro-mortar Grout Micro-J or polyester resin in a two-compartment extrudable cartridge PROFIX. For the preparation of the mortar insert 2/3 of the total mix water in the mixer, gradually add the product and the remaining water, until you obtain a uniform mix of the desired consistency. Pour the mixture prepared in the seat of reconstruction, prop it up and level it until it is perfectly smooth.
