Segmental Retaining Walls (SRW) are modular retaining walls that either holds or retains soil behind it. They are used for vertical grade changes and create more usable space.
SRW walls can be designed as either gravity or as reinforced walls. Gravity walls use their own weight to retain the soil and are typically used for smaller retaining wall applications. Reinforced walls need additional materials to assist with the earth retention to provide more strength to the structure. In SRW walls, geogrid is typically used for additional reinforcement in these applications but other options such as soil anchors, no-fines concrete, etc. may also be used.
