Joint seal


A simple and safe additional sealing in sealing joints of tunnels can be achieved with the B-STING® 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
