When trenching is installed parallel to footings and walls, it is essential to avoid encroaching upon the bearing plane. The bearing plane is the layer of soil or rock that supports the weight of structures above it, providing essential stability and load-bearing capacity. Disturbing this area can lead to settling or shifting of the structure, which compromises its integrity.

Maintaining the integrity of the bearing plane is crucial for structural safety. Trenching too deeply or too close can weaken the load distribution of the wall or footing, potentially leading to structural failure over time. Therefore, it is critical to adhere to this guideline to ensure that the foundation remains stable and secure.
