The project involved abutment grouting of a culvert located beneath a railway bridge. The primary objectives were to fill existing voids and stabilize the surrounding soil to ensure the structural integrity of the railway infrastructure.

Our recent Bedrock U-Haul project (240100) was a true test of our capabilities, pushing our team to operate in extreme winter conditions while maintaining the highest industry standards

Successful Water Filter Repair in Hughenden, Alberta  Project Overview: We are excited to announce the successful completion of a water filter repair project at the water plant in the Village of Hughenden, Alberta. This project involved the application of Belzona 1111 to repair and reinforce a critical structure, ensuring its long-term durability and functionality. Project Details: Location: Village of Hughenden, Alberta Start Date: Early morning, December 4th, 2024 Project Highlights: The project was completed successfully, with all repairs meeting the highest standards of quality and durability. The use of Belzona 1111 ensured a robust and long-lasting solution, reinforcing the structure and preventing future damage.

Perfect Solution for Rehabilitation SprayWall: The Perfect Solution for Rehabilitation 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. What is SprayWall? SprayWall is a spray-applied, 100% solids polyurethane coating designed to enhance structural integrity and provide corrosion resistance. It is particularly effective for rehabilitating manholes, large-diameter pipes, and other critical underground assets. Key Benefits of SprayWall 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 Real-World Applications 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 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.

ANOTHER SUCCESSFUL PROJECT Project Completion: Firewater/Sanitary/Potable Water Riser Spray Foam Insulation Date Completed: November 24, 2024 Location: Artemis Black Water Gold Mine We are excited to announce the successful completion of our Firewater/Sanitary/Potable Water Riser Spray Foam Insulation project at the Artemis Black Water Gold Mine. This project utilized closed cell spray foam insulation to fill the culvert/protective piping installed around the risers. Project Highlights: Total Risers Insulated: 24 Heat Tracing: All risers have been heat traced Burial Depth: Each pipe is buried 3 meters underground Insulation Coverage: From the elbow of the riser to the bottom of the connecting flange daylighting above ground Riser Sizes: 2” – 12 total 4” – 1 total 8” – 7 total 10” – 4 total Materials and Methods Applied: Supply and installation of polyurethane void fill foam to pipe chases Supply and installation of a thick elastomeric UV resistant coating overtop of ccSPF This project ensures the durability and efficiency of the water risers, providing robust protection against environmental factors. We are proud of our team's hard work and dedication to completing this project successfully. 

n Prince George, BC, we successfully completed an 18-manhole structural lining project using SprayWall®. This advanced polyurethane lining restored structural integrity, extended lifespan, and provided exceptional corrosion resistance. The rapid curing time minimized downtime, ensuring quick return to service and reducing future maintenance needs. Our use of cutting-edge technologies guarantees long-lasting protection and reliability for critical infrastructure.
