What happens here

Using a Bobcat 325 mini excavator, excavate a trench along the planned retaining wall line. The goal is to dig down to virgin, undisturbed soil to ensure a stable foundation for the wall. It is crucial to be precise and avoid over-excavating (digging too wide or too deep), as disturbing the soil below the desired subgrade can create soft spots that compromise the wall's stability. If over-excavation occurs, the disturbed soil must be re-compacted meticulously.

Goal: Excavate a precise trench down to virgin soil to create a stable foundation for the retaining wall.

now as blaine is digging one of the things i want you guys to make note of is how careful he is not to oversize his excavation or go too deep in it and this is an important thing because if the bottom of his subgrade his wall is here and then he's going to put six inches of base material three quarter inch rock on top of that if he disturbs this soil below that rock it can have soft spots if he digs too deep or over digs he's got to be careful that he puts the material back but then he compacts that area that he over dug so digging to the right depth right out of the gate is a lot better than guessing putting it back and fixing it we want virgin soil as much as [Music] possible [Music]
