What is a key consideration for tank excavation in areas prone to collapse?

The most critical consideration for tank excavation in areas prone to collapse is the soil moisture content. When the soil is saturated or has high moisture levels, it can weaken the structural integrity of the soil, leading to potential landslides or collapses during excavation. Understanding the moisture content helps in assessing the stability of the soil and determining the appropriate methods to mitigate risks associated with excavation, such as implementing proper shoring or dewatering techniques.

Monitoring soil moisture is essential for maintaining safe excavation conditions. When soil is overly moist, it can create a high risk for cave-ins and hazardous working environments. So, ensuring that the moisture content is within acceptable levels before beginning excavation is paramount for a safe and effective installation or retrofitting of underground storage tanks.
