The injection packer is a tool for sealing works. It is tightly fixed in the drill hole of the building component and connects the  injection device with the building component. Under pressure the sealing material is injected into the damaged building component. Packers are made of different materials such as steel or plastic and various types of packers are available such as drive-in packers or adhesive packers etc.

There is a wide application range for injection packers: injection into dry and wet/humid building components, filling of hollows, high pressure injection up to  about 200 bar in concrete structures, crack injection (frictional connection of cracked building components), sealing of structures, elastic connection of crack flanks (varying crack widths), sealing of expansion joints.

The most important demands on injection packers are: compatibility of material and injection material as well as absolutely reliable fixing in the building component.
