This paper discusses efforts made by past researchers to steady the expansive (problematic) soils using mechanical and chemical techniques - specifically with EPS beads. lime and fly ash. Administering swelling of problematic soils is critical for civil engineers to prevent structural distress. This paper summarizes studies on reduction of swelling potential using EPS. https://www.ngetikin.com/flash-choice-1-Gallon-Roll-Cote-High-Performance-Moisture-Vapor-Barrier-Coating-and-Primer-limited-super/
