Injection products used in the repair and protection of concrete structures are used for: The filler that transmits the forces of the cracks, voids and interstices in the concrete Ductile filling of cracks, voids and interstices in concrete The expansive filling of cracks, voids and interstices in concrete It is essential that a qualified technician carry out an evaluation of the structural elements that must be repaired and name the most appropriate product composition according to the injection to be performed. Consideration must be given to the location and size of cracks and joints , possible movement of the substrate and the effect on the stability, durability and function of the structure, as well as the risk of creating new cracks as a result of the treatment.
Crack treatment must be done in accordance with the principle and method chosen from European Standard EN - and with the following requirements: Cracks must be cleaned in accordance with section .. of the EN - standard. The substrate must be free of dust , loose material, surface contaminants, and materials that reduce or prevent USA Email List adhesion, suction, or wetting by the repair materials. Unless cleaning is carried out immediately before application of protective and repair materials, the cleaned substrate must be protected from the risk of recontamination. Cracks treated to restore structural integrity Cracks that are treated to restore structural integrity must be filled with an adhesive product or system.
Cracks that are treated to prevent the penetration of agents They must be filled or sealed. Cracks treated to absorb movement They must be repaired in such a way that they form a joint that crosses the thickness of the crack pending repair, completely filling it with a flexible material. Some points that must be taken into account for the repair are: Source: Anfapa Fissures or cracks will be sealed previously and superficially with an epoxy putty. Once the sealing putty has hardened and the injectors have been placed, you can proceed with the injection. Source: Anfapa Injector placement It is advisable to place them between and cm , depending on the thickness of the fissure.
