Terraces and Structure

Document imprimable.pdf

Building a series of walls on a slope requires careful planning. Follow this simple set of rules:

When the walls are spaced far enough apart they are engineered as two independent walls.
  • The height of the upper wall should be less than or equal to the height of the lower wall.
  • The distance between the walls must be at least twice the height of the lower wall.

As the upper wall moves closer to the lower wall, it adds pressure (surcharge) to the lower wall.

The lower wall will need to be engineered to account for the added weight and pressure, and extra reinforcement may be required.
