sallis clay with a Unified Salls ClassificatIon of CL and a plasticity index greater than 20. The
soli Is highly expansive. A minimum of 12 II crushed rock should be installed with tracked
excavation equipment to moderate the effect of the expansive solis at the proposed building
sIte, The crushed rock should be placed and then compacted with either a vibratory plate or
roller. Drainage shall be installed at the perimeter footings to help maintain optimum soli
moisture at the site. With the placement of the crushed rock, and combined with the
excavation that Is of adequate depth and width, the site a~ prepared is adequate to assure a
stable moisture content for the proposed foundation.
