What is the minimum required cover for underground conduits?

The minimum required cover for underground conduits is typically 18 inches. This standard is established to protect the conduits from physical damage due to surface activities, such as heavy equipment or weather conditions. Providing adequate cover helps ensure that the conduits are not exposed to potentially harmful forces, including shifting soil and erosion, which could compromise their integrity and functionality.

The 18-inch standard also facilitates compliance with safety regulations and construction practices that aim to minimize risks associated with underground installations. Proper depth ensures that conduits remain accessible for maintenance while ensuring that they are adequately protected over their lifespan.
