Using covers or blankets to prevent soil erosion is primarily aimed at protecting exposed soil from wind and water erosion, which is crucial for maintaining site stability during construction. When soil is left uncovered, it is highly susceptible to being washed away by rainfall or blown away by strong winds. This not only leads to the loss of valuable topsoil but can also contribute to sedimentation in nearby waterways, worsening water quality and harming aquatic ecosystems.

By applying covers or blankets, the surface of the soil is shielded from these forces. This protective layer helps to keep soil particles intact and promotes more effective erosion control. The result is a significant reduction in the risk of soil erosion, which is vital for preserving the integrity of the construction site while minimizing environmental impact.

While promoting vegetation growth, enhancing aesthetics, and assisting with water retention are additional benefits of using covers or blankets, the foremost rationale directly relates to preventing erosion and ensuring the stability of the site during construction activities.
