There are over 800,000 miles of public sewer lines in the United States, with another 500,000 miles of private lateral lines connecting residential and commercial properties to those municipal systems. Over three-quarters of Americans rely upon their local municipal sewer to meet their sanitation needs. Many of these systems are aging and in urgent need of repair due to years of corrosion caused by hydrogen sulfide (H2S). Updating and replacing existing sewer systems can be a massive undertaking, often costing municipalities several million dollars and disrupting service to the residents.

The Sprayroq Golden Touch

Sprayroq’s flagship product, SprayWall Structural Polyurethane, offers an attractive alternative to sewer replacement. A spray-applied, self-priming polyurethane lining, SprayWall reinstates structural integrity while also providing infiltration control and chemical resistance. The lining can be applied in variable thicknesses and is designed to provide protection for up to 50 years. SprayWall begins to gel in 8 seconds after application and achieves a tack-free condition after only 2 minutes. Initial curing is completed within 60 minutes, allowing the structure to accept flow as the curing process continues over the next 72 hours.

100% VOC-free and NSF 61 approved, SprayWall is ideally suited for DOT, wastewater, and stormwater rehabilitation projects throughout the Sacramento area. As a Sprayroq Certified Partner (SCP), Express Sewer & Drain is licensed, trained, and supported by Sprayroq operations technical staff to apply SprayWall and other polyurethane coating products without disrupting local community infrastructure.
