Setback
The distance that a course of retaining wall blocks is offset rearwardly from the course beneath it.

Sliding

|
|
Stepping up the wall base
Method used to maintain a level wall on a slope.

Surcharge
External load, usually applied at the top of a SRW. A roadway or building foundation can be a surcharge.
|
