Ground stabilization in expansive soils using engineered plastic columns: a quantitative experimental study

Key Points

• Ground stabilization was significantly improved using engineered plastic columns in the experimental design.
• The study observed a reduction in soil swelling by approximately 30% after treatment with the plastic columns.
• Quantitative analysis of soil stability was performed over six months of observation, revealing effective long-term results.
• These findings suggest engineered plastic columns can be a viable solution for construction in expansive soils.
