LEAKAGE REPAIR
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 a specially formulated Polyurethane System. The actively flowing water will be stopped by injecting material which reacts quickly with the water to form an expanding foam.

The ENDURA PU 10 is a semi-rigid or flexible closed-cell and strong bonding seal. To control the speed of the chemical reaction, a certain percentage of accelerator is added. The amount of accelerator added allows to control gel times between a few seconds and several minutes.

In spite of all the best efforts of engineers, architects and contractors, structures develop cracks in unanticipated places. When the structure settles and any movement finally stops, the crack becomes stable. Most cracks, however, continue to "WORK" due to several influences such as thermal or stress induced forces and soil moisture changes. Crack movement usually occurs in cycles.

Cracks contract and expand periodically over time, which may be as long as a year or as short as several hours. Since most structures experience periodic movement, rigid crack repair materials often fail or cause other cracks in areas nearby.

Therefore, even if water infiltration was successfully stopped initially, the ongoing movement of the structure might cause a new failure. The Flexible Polyurethane Injection System (ENDURA PU 10) was designed with these problems in mind.

The ENDURA PU 10 has been designed for leakage repair in problem areas such as expanding and contracting cracks, expansion joints and cold joints. ENDURA PU 10 forms a flexible gasket in the defective concrete, thus stopping the leak and tolerating movement of the structure.
