A keystone retaining wall is a type of modular retaining wall constructed using interlocking concrete blocks known as "keystone" blocks. These blocks are designed to fit together without the need for mortar, creating a strong and stable wall that can support soil and resist lateral pressure. Keystone retaining walls are commonly used for landscaping, erosion control, and creating level areas on sloped terrain.
