SGLA LARE Grading, Drainage and Stormwater Management Practice Exam

The vertical structural member that is driven into the ground to support loads is called a pile. Piles are typically used in construction to transfer the load of a building or structure deep into the ground, often when the surface soil does not have the capacity to support the loads due to its weak or unstable nature. They are installed vertically and can be made from various materials, including wood, concrete, or steel.

Piles offer significant advantages when working on challenging sites, including their ability to reach stable soil or bedrock at greater depths. This makes them particularly useful in areas with poor surface soil conditions, such as soft clays or loose sands.

Understanding piles is essential in the context of grading, drainage, and stormwater management, as the load distribution and stability of structures directly relate to the interaction between the structure and the underlying soil or bedrock. This knowledge is crucial for ensuring that any grading or stormwater systems implemented around the structure do not compromise its integrity or lead to failure in the support system.
