Aging infrastructure is a common problem in municipalities across North America. Wastewater treatment tanks with leaking cracks are a particularly serious problem because the result is often environmental contamination. Administrators at a wastewater treatment plant in New York City contracted LJS Waterproofing to repair 39 leaking concrete tanks. An experienced LJS crew arrived on the scene shortly thereafter, ready to take on this critical threat to the environment.
Powerful Polymer
The LJS crew injected Spetec PUR F400 to seal the leaking cracks. This material is a solvent and phthalate-free, water-reactive, hydrophobic, closed-cell, low viscosity, shrink-free, flexible, one-component polyurethane injection resin designed to shut off water leaks.
Painless Procedure
Concrete crack injection with polyurethane resin is a five-step process:
- Drill the injection hole.
- Flush debris out of the hole with water.
- Install the injection port.
- Flush the crack with water.
- Inject the resin.
For a complete overview of the crack injection process LJS professionals used on this job, see the Alchemy-Spetec blog post series 5 Steps of Concrete Crack Injection.
Rapid Result
LJS Waterproofing sealed every leaking crack in all 39 concrete tanks, preventing any future wastewater from leaking into the surrounding environment. The administrators at the New York City wastewater treatment plant were extremely happy with the results.
