-4: Raised Soil Pad
If the installation site is flat or is in a low area, compactable soil material must be brought to
the site to create the proper grading under the home. The fill material for the pad of soil must
be placed on each home installation site such that the dimensions of the pad will extend a
minimum distance of 10 ft beyond each side of the home. The location where the soil pad fill
material will be placed must be free of any organic debris (such as vegetation, wood, roots,
twigs, dead branches, grass and brush). The soil pad material is to be applied in thin consistent
layers, not exceeding 8 inches, with each layer compacted to at least 90 percent of its
maximum relative density before the next layer is placed. This method should provide the
proper load bearing capacity for the support pier footings. Layers exceeding eight (8) inches
can result in inadequate compaction and future settlement. Loose sand, gravel or other non-
compactable materials are not to be used as the fill material for the pad. The soil under the
home shall be adequately crowned and sloped from the centerline of the home providing a
minimum slope of ½ inch per foot from the center of the soil pad to the distance 10 ft away
from each side and end of the home (see Figure 5). Exceptions to these requirements may be
allowed where property lines, retaining walls, slopes, mature trees or other physical conditions
prohibit achieving the minimum distance from the sides and ends of the home. All depressions
in the soil pad resulting from the use of the transportation equipment moving the home onto the
installation site shall be properly filled and graded by the installer/transporter before departing
the installation site.
