Undercutting

Term from Excavation industry explained for recruiters

Undercutting is an important excavation technique where workers remove unstable or unsuitable soil beneath the main dig level to create a stable foundation. Think of it like removing a weak bottom layer of soil and replacing it with stronger materials to ensure whatever is built on top stays secure. This process is common in construction projects, especially when preparing ground for buildings, roads, or other structures. It's similar to how you might remove a weak bottom card in a house of cards to replace it with a stronger one - except this is done with soil and on a much larger scale.
