When it comes to rehabilitating underground infrastructure, finding a solution that combines ease of installation with exceptional structural integrity is crucial. Sprayroq’s SprayWall stands out as an industry-leading choice for such projects, offering unmatched strength and durability.

SprayWall lining is a high-performance trenchless solution used for pipeline, culvert, and manholes rehabilitations. This spray-applied polyurethane creates a seamless, monolithic barrier that enhances structural integrity, providing structural reinforcement, corrosion resistance, and long-term durability for aging infrastructure.

Superior Strength: SprayWall boasts a compressive strength exceeding 18,000 psi, significantly higher than typical Class A concrete, which has about 4,000 psi. This ensures it can withstand enormous hydrostatic, soil, and traffic loads.

Tensile Strength: With a tensile strength greater than 7,450 psi, SprayWall surpasses the capabilities of traditional concrete, reducing the risk of cracks and structural failure

Rapid Cure Time: SprayWall cures quickly, becoming tack-free within seconds and achieving initial cure within an hour. This minimizes downtime and allows for faster project completion

Abrasion and Corrosion Resistance: SprayWall is highly resistant to abrasion and the chemicals typically found in municipal sewage, ensuring long-term durability

Seamless Application: Applied in a continuous process, SprayWall creates a joint-free lining that eliminates weak points and potential leak paths, enhancing the watertightness of the structure

SprayWall has been successfully used in various rehabilitation projects, from manholes to large-diameter pipes. Its ability to conform to irregular surfaces and bond securely with existing materials makes it a versatile and reliable choice for maintaining and enhancing underground infrastructure.

SprayWall lining is widely used across Canada and the United States for municipal and industrial infrastructure rehabilitation projects.

Conclusion

For those looking to rehabilitate underground assets, SprayWall offers a superior solution with its impressive strength, rapid cure time, and resistance to environmental stressors. It provides a cost-effective and long-lasting option for ensuring the integrity of critical infrastructure.
