Pentens continuously develops and refines Crack Injection Systems and recommendations. High Pressure Polyurethane is an important system used by thousands of applicators. Basic product knowledge helps users to reduce possible problems. The right injection technology should be identified before the project is started.

 

Epoxy injection resins usually “fail” in stopping active water leakage because of their slow reaction time and inability to bond to wet surfaces; this failure is resolved with the Pentens Polyurethane System.

 

The actively flowing water will be stopped by injecting Pentens PU-108,  PU-168, PU-300 which reacts quickly with the water to form an expanding foam. The final product is a semi-rigid or flexible closed-cell and strong bonding seal. To control the speed of the chemical reaction a certain percentage of a accelerator is added. The amount of accelerator added allows to control the gel times between a few seconds and several minutes.
