When is solid sheeting typically used in trenching?

Solid sheeting is typically used in trenching when the surrounding materials do not have the ability to stand vertically on their own. This situation commonly arises in soft or unstable soils where excavation may cause the walls of the trench to collapse. Solid sheeting provides necessary support by preventing the soil from caving in and maintaining the integrity of the trench walls, ensuring a safer working environment for personnel and equipment. The use of this method is crucial in preventing the potential hazards associated with trench collapses, particularly in certain soil conditions that lack the structural stability required for vertical support.

Other scenarios, such as seeking quick access or providing temporary support, may involve different methods of trench shoring or bracing that are more suitable for those specific conditions. However, the central role of solid sheeting is to address the challenges posed by unstable materials that cannot remain upright without assistance.
