Dorval Exchange

Project: Installation of Roadway Drainage Channels on the Dorval Interchange

Product Used: ABT Polydrain Interceptor A-67

Project Overview:
As part of the rehabilitation and redevelopment of multiple sections of the Dorval Interchange — a critical component of Quebec’s highway network — ABT Polydrain Interceptor A-67 trench drains were installed to ensure reliable and long-lasting surface water management.

Technical Features of the Installed System:

• Precast polymer concrete trench drain, specifically engineered for heavy-duty roadway applications.

• Integrated one-piece surface grates, ensuring structural strength, vehicle safety, and a smooth driving surface.

• Built-in 0.6% longitudinal slope, allowing efficient linear drainage without the need for additional grading.

• Uniform 12-inch depth, compatible with highway-grade infrastructure designs.

• Discharge sumps up to 1.7 meters deep, enabling rapid collection and conveyance of stormwater into the underground network.

• Certified and approved by the MTQ, making it one of the few trench drain systems authorized for provincial infrastructure use.

System Advantages:

• High resistance to dynamic loads, ideal for heavy-traffic zones and transportation corridors.

• Modular installation across multiple sections while maintaining consistent hydraulic performance.

• Exceptional durability under harsh Quebec climate conditions (freeze-thaw cycles, deicing salts, abrasion).

• Fully compliant with road safety and winter maintenance standards.

Conclusion:
The Polydrain Interceptor A-67 proved to be the optimal linear drainage solution for the demanding conditions of the Dorval Interchange project, combining hydraulic efficiency, structural resilience, and regulatory compliance.
