What is required when a pipe passes through a footing or foundation wall?

When a pipe passes through a footing or foundation wall, a relieving arch or pipe sleeve is essential for ensuring the integrity and structural stability of the wall or footing. The purpose of the relieving arch or pipe sleeve is to manage the load of the surrounding material and prevent any potential damage to the pipe itself as well as to the structural elements of the wall or footing. This installation allows for necessary movement and expansion of the pipe, while also providing protection against soil pressure, moisture intrusion, and potential cracking of the foundation material.

Using a pipe sleeve, which is a protective enclosure around the pipe, can help to accommodate any movement due to temperature changes, ground settlement, or other environmental factors. This installation method is a standard practice in plumbing and construction to promote longevity and safety in building systems.
