Stem Wall Backfill
Density tests and Hand Cone Penetrometer (HCP) readings were made in the stem wall backfill (slab area)
to a depth of four feet at a minimum of three locations. Density tests were performed in the upper one foot
of fill. HCP readings were taken in hand auger boreholes at one foot intervals from slab grade through the
depth of fill. At the time of our testing no information was available regarding the foundation setbacks.
The density tests were performed in general compliance with ASTM D 2922. The HCP test, in conjunction
with information about the soil type, is empirically correlated to the relative density of subsurface soils.

In the locations and depths that were tested, the stem wall backfill (slab area) has been compacted to a
minimum of 95 percent of the modified Proctor maximum dry density (ASTM D 1557). No soil borings
were performed below the recently placed fill.
