Types of Retaining Walls

Retaining walls are essential structures that hold back soil and prevent erosion, offering both functional support and aesthetic appeal to various landscapes. On the iseekplant platform, we categorize these walls based on their construction methods and materials.

Below, let's look at the diverse types of retaining walls available to best suit your project needs.

  • Block Retaining Wall: Block retaining walls are modular systems offering a modern design with each block interlocking into the next.
  • Rock Retaining Wall: Rock retaining walls are large rocks stacked together, combining strength and a natural aesthetic.
  • Gabion Retaining Wall: Gabion retaining walls are built like cages or boxes filled with rocks or concrete, offering both strength and flexibility.
  • Boulder Retaining Wall: Boulder retaining walls utilise larger boulders stacked together, perfect for holding back significant soil amounts.
  • Concrete Sleeper Wall: Made of upright concrete posts and horizontal sleepers, concrete sleeper walls are popular for their durability in various applications.
  • Gravity Wall: Rely on their weight to hold back the soil.
  • Anchored Wall: Use anchors placed in the soil behind the wall for added strength.
  • Cantilevered Wall: Built with a stem or thin vertical wall attached to a base slab.
  • Sheet Piling Wall: Sheet piling are thin walls of steel, wood or vinyl driven into the ground, ideal for tight spaces.
  • Reinforced Wall: Combine reinforcing bars with concrete for added durability.

Applications of Different Retaining Wall Types
