Building Code 2015 of Utah > 18 Soils and Foundations > 1808 Foundations > 1808.6 Design for Expansive Soils > 1808.6.3 Removal of Expansive Soil
JUMP TO FULL CODE CHAPTER
Where expansive soil is removed in lieu of designing foundations in accordance with Section 1808.6.1 or 1808.6.2, the soil shall be removed to a depth sufficient to ensure a constant moisture content in the remaining soil. Fill material shall not contain expansive soils and shall comply with Section 1804.5 or 1804.6.
Exception: Expansive soil need not be removed to the depth of constant moisture, provided the confining pressure in the expansive soil created by the fill and supported structure exceeds the swell pressure.
