The answer to 'types of retaining wall' is that there are several common types of retaining walls homeowners can choose from, each with their own advantages and considerations. The most popular options include gravity walls, cantilever walls, anchored walls, and segmental walls.
Gravity walls rely on the weight and interlocking design of the wall blocks or stones to hold back the soil. Cantilever walls use a reinforced concrete stem that extends into the soil behind the wall to provide support. Anchored walls use cables or rods that are embedded into the soil to stabilize the wall. Segmental walls are made up of individual concrete or stone blocks that interlock together without mortar.
