Hanna Rubber’s bridge troughs are engineered to defend critical joints from water, debris, and structural wear—keeping your infrastructure dry, protected, and performing.
Bridge troughs serve an essential yet often overlooked role in joint protection. Positioned beneath expansion joints, they channel runoff, debris, and grit away from structural connections, ensuring the integrity of seals and extending service life.
At Hanna Rubber, we manufacture precision-cut bridge trough systems from engineered elastomers that flex with joint movement, resist chemical exposure, and last for decades with minimal maintenance.
What Makes Our Bridge Troughs Different?
Our solutions are designed for high-performance environments like highway bridges, pedestrian walkways, and rail crossings. Every trough system is custom-shaped to meet the specific demands of your joint design.
Integrated with thermal break materials when needed, these systems form a complete protection strategy.

FAQs
Q: What is the main purpose of a bridge trough?
A: To protect expansion joints by directing water, grit, and debris away from sensitive structural components.
Q: Can your systems integrate with thermal break materials?
A: Yes—Hanna Rubber provides complete, integrated joint protection packages.
Q: How long do your bridge trough systems last?
A: With proper installation, many of our troughs last 30–50 years with little to no maintenance.
Q: Are these products suitable for heavy traffic bridges?
A: Absolutely. They are engineered to withstand vibration, load cycling, and environmental exposure.
Final Take
Bridge joints are where failure often begins—but not when they’re protected by Hanna Rubber bridge troughs. Our precision-molded solutions offer decades of defense with minimal maintenance. Contact us today to request a technical spec or engineering consultation.
