DESOI sealing cone system
The Injection process

First class injection work with minimal cost – Procedure according to ZTV-ING*

Work steps

1. Clamp steel packer in prepared bore hole
- Tighten only the nipple of the steel packer
that is injected first
- Loosen the nipples of the other steel packers
by one rotation
2. Inject steel packers
- Inject the first steel packer until filler escapes
the second steel packer
- Tighten the nipple of the second steel packer
- Inject the second steel packer until filler escapes
the third steel packer
- Repeat the 2nd work step until the crack
is completely injected
- Within the processing time of the filler
re-inject each steel packer
* Additional technical contract terms and guidelines for engineering structures


Usable for all steel and stainless steel packers with external thread M6 and M8.
The opening pressure for the HP-Variants is approx. 15 – 20 bar and for the LP-Variants approx. 2 – 3 bar.


Combine the DESOI sealing cone system with the DESOI w.i.l.m.a. and achieve optimal injection results.
