Leak Seal Solutions for Municipalities (1)

Nationwide, municipalities regularly deal with the issue of infrastructure deterioration. One of the most common types being the constant appearance of water leaks. Active leaks, when untreated, can cause an accelerated deterioration of reinforcement within concrete, as well as settlement issues caused by voids below and next to structures.

The purpose of this article is to illustrate how polyurethane injection can be used as a preventative measure to prevent more serious problems.

Municipal Structures Vulnerable to Infiltration

Various areas in the wastewater, drinking water and storm water system may require polyurethane to stop infiltration. This is mainly due to its clean application and rapid results. These areas include but are not limited to:

  • Manholes
  • Water Treatment and Storage Tanks
  • Lift Stations
  • Storm and Sanitary Pipes

How Spetec GT500 Seals Hairline Cracks

This graphic depicts the polyurethane leak seal process when applied to the wall of a water tank. Our leak seal resin, Spetec PUR GT500, reacts when it comes into contact with water. It bonds to concrete in a durable manner, yet remains flexible so as not to crack if the concrete shifts in the future. High pressure injection insures that every part of the crack is filled and permanently sealed. This product is certified To NSF 61-5 (approved for contact with drinking water).

How Spetec PUR H200 Stops Gushing Leaks

This graphic depicts the process when applied to a larger leak with a void in the soil on the other side. While the graphic depicts a box culvert, voids like this can develop next to water tanks that are built against a hillside, manholes, pipes, etc. Spetec PUR H200 is used to fill the void and stop the gushing leak in the process. This product is certified To NSF 61-5 (approved for contact with drinking water).

Another Common Issue: Leaks in Equalization Tanks

Another common issue is leaks around the bases of equalization tanks. This untreated water can present a hazard to employees. Left unaddressed, it just costs more and more money to keep pumping this water back out.

Conclusion

Regardless of the leak seal issue at hand, one thing is certain: left untreated it will cost more money and do more damage in the long run. In this case the old adage “An Ounce of Prevention is Worth a Pound of Cure” is completely appropriate. Are you a municipal manager facing any of these issues?
