When working in traffic areas, what is the required depth for the trench?

The required depth for the trench in traffic areas is essential for ensuring structural integrity and safety. Having 18 inches of bedding provides a solid foundation for the pipe or tank being installed, distributing loads effectively and reducing the risk of settling or damage due to vehicular traffic. The additional 6 inches of back-fill material helps to protect the installation further by providing an additional layer of support and preventing the intrusion of surface water.

This setup aligns with industry standards that prioritize safety and durability in environments with heavy traffic. The proper depth and material specification are crucial to avoid potential hazards and ensure the longevity of the installation. The combination of bedding and back-fill allows for effective drainage, prevents soil erosion, and accommodates freeze and thaw cycles, which are vital considerations in many regions.
