Jet Grouting Rods

The jet grouting rod ends are constructed from the same high strength steel utilized in all percussive casing. Rod ends are then nitrated and friction welded to an annealed steel mid-body.

Inner tubes in the dual tube systems are secured inside the outer rod utilizing a circlip or wire fuse connection. This allows for easy removal, repair, or replacement of the inner rod as required.

The sealing materials in the jet grouting systems are specially designed to resist damage from the abrasive grouts and numerous make and break cycles, which limits the amount of time spent changing rod seals and maximizes time spent grouting.
