Stepping Up The Wall Base

Document imprimable.pdf
Walls built on a sloping grade require a stepped base.
  • Begin excavation at the lowest point and dig a level trench into the slope until it is deep enough to accommodate the base material and one entire block.
  • At this point step up the height of one block, and begin a new section of base trench.
  • Continue to step up as needed to top of slope.
  • Always bury at least one full unit at each step.
