What is the purpose of bedding in a trench?

The purpose of bedding in a trench is to provide support to the pipe being installed. Proper bedding creates a stable and level foundation, which helps to prevent movement or shifting of the pipe once it is installed. This is critical for maintaining the integrity of the pipe system, as any displacement can lead to misalignments, stress on joints, and ultimately, failure of the pipes.

Additionally, the type of material used for bedding can help accommodate any thermal expansion and contraction of the pipe, further reducing the risk of damage. A well-prepared bedding layer ensures that the pipe is adequately supported along its entire length, promoting longevity and consistent performance in utility systems.
