Sentence examples for soil expansion from inspiring English sources

It is the depth or zone where soil expansion or shrinkage forces adversely affect deep foundation performance.

Montmorillonite, illite and kaolinite were investigated, for these clay minerals are key indicators of soil expansion and shrinkage potential.

Winter freeze-thaw led to soil expansion, likely related to frost-heaving, causing a net centimeter-scale elevation increase across soil-mantled slopes.
