Stepping Up the Base

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.

Start retaining wall at the lowest elevation.
