deep level clearing

The deep-level clearing is a method to rehabilitate areas. The term is also used in construction.
The deep-level clearing is clearly not a process of cleanup, it is a process of rubble clearance with the objective of reusing the areas differently.
The deep-level clearing might be destructive in some parts, but not in its totality.
Demolition grab, hydraulic hammer, sorting grab, backhoe bucket and screening bucket are tools for the deep-level clearing with specific characters.
The deep-level clearing is not completed, because that’s what it can never be.
