Sleeve pipes

Sleeve pipes are injection pipes made of solid PVC or steel, featuring strategically placed perforations.  Each perforation is covered by a rubber sleeve that  inflates under injection pressure, allowing the injected material to escape into the surrounding area.

The spacing between the rubber sleeves can be adjusted to suit specific tasks.After completing the injection process, the sleeve pipe should be thoroughly rinsed. If needed, a subsequent grouting process can be performed at a later time.

 Technical and economic benefits of the sleeve pipe method:

  • the reliable production of an injection body
  • the option of subsequent grouting
  • the separation in time and therefore the independence of drilling and injection work
