We are pleased to announce the successful completion of the Squamish Culvert Rehabilitation project in Squamish, British Columbia. This initiative focused on restoring a 1.2-meter diameter, 19.5-meter long culvert to ensure its structural integrity and functionality.
Project Overview:
The primary challenge of this project was managing water flow during rehabilitation. Our team implemented an effective bypass system by excavating a sump and deploying four pumps to redirect water, allowing for a dry and safe working environment.
Rehabilitation Process:
Soil Stabilization and Void Filling: We utilized a high-quality, two-component rigid polyurethane foam system. This material is specifically designed for lifting and leveling concrete structures, as well as stabilizing soils. Key properties include:
Density: Approximately 4.9 lb/ft³ (78.4 kg/m³)
Compressive Strength: Ranging from 60 to 75 psi (413 to 517 kPa)
Dimensional Stability: Maintains structural integrity under varying temperatures
Water Absorption: Low, at 0.67%
Structural Lining Application: Following stabilization, we applied SprayWall®, a spray-applied polyurethane lining known for its exceptional strength and durability. This lining offers:
Compressive Strength: Exceeding 18,000 psi, providing robust structural support
Tensile Strength: Greater than 7,450 psi, ensuring resilience under stress
Rapid Cure Time: Becomes tack-free within seconds, allowing for quick project turnaround
Corrosion Resistance: Highly resistant to abrasion and chemicals commonly found in municipal sewage
Environmental Considerations:
Throughout the project, we prioritized environmental stewardship. Our methods ensured minimal impact on the surrounding ecosystem, leaving the site with a near-zero footprint.
