Bill Schwab is an unknown quantity at this point
WE always tie all sides together using Geo-Grid (Stratta Grid 300) when we build a raised patio. In areas that freeze, it will hold all the sides together in case water locks inside. I like the use of clear gravel throughout the patio, with fabric over the top to prevent the sand from sifting down into the voids. If you place a 3 or 4" sdr-35 perf pipe in back of the wall, and tie it to an underground drain or daylight, there will be very little chance of settling.

If we open any trneches under where footing will go, we use a Wacker jumping jack style compactor in the trench and try to get as close to 100% as we can. Any pipe that runs under the wall is sleeved with schedule 40.

In the year 1491, if the Naturescape Landscape Company did the site work in Pisa, Italy, they would not be calling it the "leaning" tower.
