Our structural lining process using SprayWall® involves meticulous preparation and application to ensure long-lasting results. This process not only enhances the structural integrity of the manhole but also provides exceptional corrosion resistance, ensuring durability and reliability.

Structural lining is widely used in municipal and industrial infrastructure projects. Our services are ideal for manholes, sewer systems, pipelines, and other underground structures requiring rehabilitation and protection. SprayWall® lining provides a seamless barrier that enhances structural integrity and extends the service life of aging assets.

SprayWall® structural lining is applied as a seamless coating that reinforces and protects existing infrastructure without the need for excavation. At QIS, we deliver advanced structural lining services designed to reinforce manholes, pipelines, and underground structures while providing long-term corrosion resistance and durability. Our solutions are engineered to perform in demanding environments across Canada and the United States.

Structural lining, also known as SIPP (Spray-In-Place Pipe), pipe lining or trenchless pipe lining, is a modern solution for rehabilitating pipelines without excavation. This method provides a seamless and durable lining that restores structural integrity and extends the life of existing infrastructure.

This trenchless method minimizes disruption while delivering long-lasting structural performance.

Proper surface preparation is critical to ensure the success of structural lining applications.

Thorough Cleaning: The structure is cleaned to remove debris, grease, and contaminants, ensuring optimal adhesion of the SprayWall® material.

Surface Repair and Smoothing: Any voids, cracks, or damaged areas are repaired using appropriate materials to create a uniform surface prior to coating application.

Once the surface is properly prepared, the SprayWall® structural lining is applied.

SprayWall® Application: A high-build, fast-curing polyurethane coating is applied to form a seamless, joint-free lining that reinforces the structure.

Rapid Curing: The fast curing properties of SprayWall® allow structures to return to service quickly, minimizing downtime and operational disruptions.

Enhanced Structural Integrity: The seamless, joint-free lining significantly improves the structural strength of the manhole.

Corrosion Resistance: SprayWall® provides exceptional resistance to corrosion, extending the lifespan of the manhole.

Reduced Downtime: The rapid curing time ensures that the manhole can be returned to service quickly, reducing downtime and inconvenience.

Cost-Effective Rehabilitation: Structural lining offers a cost-efficient alternative to full replacement of infrastructure.

Long-Term Performance and Durability: Structural lining systems are designed for long-term performance in harsh environments. SprayWall® technology provides a durable solution that resists wear, chemical exposure, and environmental stress, ensuring reliable infrastructure performance for years to come.
