Re-Injectable Tube System

The Spetec Re-Injectable Tube System is a primary waterstop in cold joints and pipe joints. When used with acrylates like Spetec AG200, it can be flushed with water at a pre-determined set time, creating a clean tube ready for subsequent use. It can also function as a standard single-use injection tube system with polyurethane injection resins like Spetec PUR H100 and Spetec PUR F400. The Spetec R-ITS is compatible with combination grouting techniques involving microfine cement.
