What technique is commonly used for soil stabilization?

Adding lime is a well-established technique for soil stabilization. This method involves mixing lime with soil to enhance its stability and load-bearing capacity, particularly in clay or other fine-grained soils. Lime reacts chemically with the soil and water to produce pozzolanic reactions, resulting in a more solid and durable material. This process can significantly reduce plasticity and improve the soil’s strength, making it easier for construction projects to proceed without structural issues.

In contrast, while planting vegetation can also stabilize soil through root systems, it primarily provides erosion control and may take time to establish effectiveness. Covering with tarps does not contribute to the intrinsic properties of the soil and is mainly used for temporary protection. Frequent watering can help maintain moisture levels but does not fundamentally alter the soil's structural integrity or stabilizing properties. Therefore, adding lime stands out as the most effective technique for enhancing the stability of soils in construction and excavation contexts.
