A wetting-induced decrease in the height of a soil element, common in loosely compacted or naturally porous soils. Swell Pressure:

| Method | Name | Key Procedure | |--------|------|----------------| | | Swell under a specified constant surcharge | Sample inundated at a fixed vertical stress (e.g., 1 psi or user-specified). | | B | Swell under a sequence of applied loads after wetting | Wetting occurs first, then loads are applied incrementally to measure swell potential. | | C | Collapse potential | Sample loaded to field stress, then inundated to see collapse strain. | Astm D4546-21 Pdf

The results from an ASTM D4546-21 test typically yield the following data: ASTM International A wetting-induced decrease in the height of a
