How To Prepare The Site For A Wall

Excavate and Lay Out: Start with a preliminary excavation to create a wide, level area where the wall is to be located, and grade the area on the downhill side of the wall. Then drive stakes a few inches to the downhill side of the wall location; stretch a level mason's twine between the stakes about 6 inches above the grade. Hook a line level over the string and move one end of the string up or down as needed.

Excavate Footing Trench: Excavate an 18 in. wide by 6 in. deep trench on the uphill side of the line. Fill the trench with crushed stones and rake it level. Then use a tamper to compact the stones. Place a 2x4 straightedge on edge and place 2 ft. level on it to verify the gravel footing is level.

Helpful Hint: If you prefer a gently curving wall, lay down a garden hose or length of rope to guide your excavation instead of stakes and string.
