Background: Geotechnical engineers working on the ground face a common obstacle of unsuitable soil. Expansive soil is one of the soils vulnerable to high loads and unstable. Properties such as high permeability, low bearing capacity, compression, swelling and shrinkage behavior, low strength and stiffness are all characteristics of an expanding soil. Expansive soil is weaker than other soil types due to these characteristics. Objective: This study aimed to review the efficacy of the widespread use of ionic soil stabilization techniques for improving expansive clay soil properties by using different dosage levels that affect the properties of expansive clay soil. Results: expansive soil's high sulfate content, experiences swelling and heaving when stabilized with cement, lime, and fly flash. Engineers developed a new stabilizer called ionic soil stabilization to address this issue, improving strength and stiffness while reducing expansive soil permeability, compressibility, swelling, and shrinkage. Conclusion: Ionic soil stabilizer is preferred for improving clay soil because of its high efficiency and environmentally friendly stabilizer material, and low cost.
