Modern hybrid mortar in combination with commercially available threaded rods with 3.1 certificate for the highest loads in cracked concrete The VMH injection system is a versatile injection nozzle system for anchoring maximum loads in cracked and non-cracked concrete. It consists of a styrol-free hybrid chemical injection mortar in a mortar cartridge and an anchor rod V-A, anchor rod VMU-A or an female thread sleeve VMU-FT. A commercially available anchor rod with a strength rating of 3.1 or concrete steel can also be used. The variable anchorage depths allow optimal adaptation to the respective mounting situation, even under seismic influence.
