A cantilever retaining wall is a relatively more complex structure. This design uses the principles of leverage to provide support and to resist overturning and sliding. The weight of the retained soil on the base slab helps to stabilize these walls and is hence believed to be an efficient solution for taller walls. Cantilever walls are often reinforced with rebar and may require geotechnical engineering expertise to ensure they meet the necessary safety factors, especially in areas with seismic activity.
Segmental Retaining Walls
Segmental retaining walls are modular systems made from interlocking concrete blocks. These walls are popular in DIY projects due to their ease of installation and flexibility in design. The blocks are designed to work together, using friction and gravity to hold back the soil. For larger or more critical applications, geogrid reinforcement may be used to provide additional stability.
