REPORT TERMINOLOGY
~ (Based on ASTM D653)
Expansive Potential The potential of a soil by expand (increase in volume) due to ab~~orption of
moisture. ~„;
Finished Grade The final grade created apart of the project.
Footing A portion of the foundation of a structure that transmits loads directly to the
soil.
Foundation The lower part of a structure that transmits the loads to the soil or bedrock.
Frost Depth The depth of which the ground becomes frozen during the wint~;r season.
Grade Beam A foundation element or wall, typically constructed of reinforced concrete,
used to span between other foundation elements such as drilled piers.
Groundwater Subsurface water found in the zone of saturation of soils, or within fractures
in bedrock.
Heave Upward movement.
Lithologic The characteristics which describe the composition and texture of soil and
rock by observation.
Native Grade The naturally occuring ground surface.
Native Soil Naturally occurring on-site soil, sometimes referred to as natural soil.
Optimum Moisture The water content at which a soil can be compacted to a maximum dry unit
Content weight by a given compactive effort.
Perched Water Groundwater, usually of limited area maintained above a normal water
elevation by the presence of an intervening relatively impervious continuing
stratum.
Scarify To mechanically loosen soil or break down existing soil structure.
Sett/emeni Downward movement.
Skin Friction (Side The frictional resistance developed between soil and an element of structure
Shear) such as a drilled pier or shaft.
Soil (earth) Sediments or other unconsolidated accumulations of solid particl~:s produced
by the physical and chemical disintegration of rocks, and which may or may
not contain organic matter.
Sfrain The change in length per unit of length in a given direction.
Stress The force per unit area acting within a soil mass.
Strip To remove from present location.
Subbase A layer of specified material in a pavement system between the :~ubgrade and
base course.
Subgrade The soil prepared and compacted to support a structure, slab or Iavement
system.
