Soil stabilization must be applied within how many days after final grade is reached?

1. 3 days

2. 5 days

3. 7 days

4. 10 days

The correct answer is: 7 days

Soil stabilization is a critical process that ensures the integrity and usability of soil, particularly after final grading is completed. The timing of this application is essential because soil can become unstable if left untreated for too long after grading. The correct timeframe for applying soil stabilization is within seven days after the final grade is achieved. This period is designed to prevent erosion and degradation of the soil structure, which can occur quickly, especially in certain weather conditions. Delaying the application beyond this timeframe can lead to increased vulnerability of the soil to erosion and other environmental factors, which could undermine the work that has been done. Proper soil stabilization measures, such as the addition of materials or chemical agents, help lock in moisture and provide necessary support to the soil, ensuring it remains stable for any construction activities that follow.
