What must be done to a sewer pipe to prevent direct contact with concrete when it is installed under vehicular traffic?

To ensure that a sewer pipe does not come into direct contact with concrete when it is installed under vehicular traffic, it is essential to encase the pipe in concrete. This method provides structural support and protection against potential damage from the weight and stresses imposed by vehicular traffic. Encasing the sewer pipe in concrete prevents soil movement and helps to minimize any potential deformation or failure of the pipe due to external loads.

Furthermore, encasement in concrete offers benefits such as an enhanced barrier against leaks and the infiltration of external contaminants into the sewer system. It helps in stabilizing the installation site, reducing the likelihood of pipe displacement over time. Given these advantages, encasement is a standard practice for maintaining the integrity and longevity of sewer systems placed beneath roads and other areas subject to heavy loads.
