Waterstops are common and come in all different shapes and sizes. What if you could install one that was 100% custom fitted for your project? Well that is how the I.T.S. (Injectable Tube System) works. It allows injection of a cold joint or construction joint via a pre-installed injection canal/hose. This is normally done with a flexible polyurethane.
The end result is a custom shaped, flexible urethane “gasket” or waterstop. The grout will even fill in any honeycombing or defects and is considered a life-of-the-structure product.
The I.T.S. can be used as a stand alone waterstop, or it can be installed inside of a waterstop and injected as needed. Settlement of a structure can eventually lead to leaks, so it is great to have a pre-installed method to address those leaks when they appear.
But wait there's more! There is also an R-I.T.S. (Re-Injectable Tube System). The Re-Injectable Tube System is very similar but is for use with acrylate grouts instead of polyurethane. It is rubber based and has slits that act like valves. This allows for the pressurized grout to travel out into the substrate. Then the tube can be flushed with low pressure water that does not open the “valves”.
