European Technical Approval (ETA) Fire Resistance  
  Injection System for cracked and non-cracked concrete
  Injection System VMZ A4 and VMZ HCR
   
   
 
   


Description
The Injection System VMZ consists of an anchor rod with conical expansion elements and a 2 component injection adhesive. This combination provides extremely high load bearing capacity even at minimum edge distance and spacing. The VMZ system combines the benefits of bonded anchors and expansion anchors in a European technical approved fastening system for both cracked and non-cracked concrete. Anchorages that have not been permitted because of concrete members that are too thin are now feasible when using the Injection System VMZ. It can be installed in wet concrete without any reduction of the load bearing capacity. Even in water filled holes, M12 sizes an larger can be properly installed with no reduction in load bearing capacity. The Injection System VMZ is an "all weather" solution that can be installed down to as low as -5°C. Optimized edge distance and spacing as well as through setting installation allows for an even greater variety of applications. The wide range of VMZ-A rods, including the new 75 M12 and 170 M24 sizes, assures the proper size necessary to design the connection most efficiently.


Adhesive VMZ
The resin is developed on vinyl ester basis, styrene free. It has excellent load bearing capacity in cracked and non-cracked concrete. Fire resistance has been tested and the certification is available.

 


Applications
Heavy duty fastenings in cracked and non-cracked concrete like steel beams, steel supports, railings, brackets, facade substructures and so on.

Pre-installation

Throuhg fastening


Drill holes with a hammer drill. Clean thoroughly with steel brush and blow-out pump. Remove caps from the cartridge and thread the mixing nozzle onto it. Fill cleaned drill hole with resin mixture. Apply conical rod by hand. A small amount of the resin mixture should come out of the hole. It can be easily removed after the curing process. Observe curing time. Apply installation torque. Detailed installation instructions come with the product.
