Joint seal


A simple and safe additional sealing in sealing joints of tunnels can be achieved with the DESOI injection drill needle, particularly for tubbing tunnels.

Screw the injection drill needle in the sealing joint by using  a cordless screwdriver
Inject the material
Nach dem Injektionsvorgang wird das Injektionsrohr durch Linksdrehung entfernt, die Injektionsbohrnadel aus Edelstahl verbleibt im Bauwerk


  • There is no loss of material by screwing the tip in the sealing joint; the outlet openings lateral remain clean and a free flow of filling material is ensured
  • The injection drill needle will be surrounded by the strong material, so that it is kept and sealed at the same time
