What is the primary purpose of cellular confinements in erosion control?

• A. Rigid plastic structure where soil can be placed into for vegetative establishment.
• B. A type of erosion control blanket.
• C. A drainage pipe.
• D. A method of seeding.

Answer: (A)

Cellular confinements provide a rigid, expandable plastic container that is filled with soil, creating a stable, contained area for vegetation to establish. This structure holds the growing medium in place on slopes or exposed soils, giving plants a quick-start environment and roots something to grip onto. As vegetation grows, the root systems anchor the soil and the confinement dissipates surface runoff, reducing erosion. The main goal is to offer a soil-filled framework that supports vegetative establishment, not to function as an erosion blanket, a drainage pipe, or a seeding method.
