General Features
- The Grout Tube is normally used to pump cementitious grouts for rock and cable bolt in post grouting applications.
- The air bleed tube (Breather Tube) is used to allow the escape of air from the bolt hole. The air bleed tube is also used to provide a positive indication of the grouting progress by visual indication of air escape and, eventually, the grout return through the tube when the hole is full.
- DSI grout tube is manufactured from polyethylene material.
- DSI air bleed tube is manufactured from high density polyethylene to resist crushing or cutting.
