I wouldn't of been real happy with that sleeve going in. Considering it is going to be 4 ft deep.....I'd imagin they just dug a 4 foot trench that cuts right through the middle of your entire project.

Gonna be very tough to get 100% compaction in a deep trench like that. Almost need a sheeps foot to really do the job right, or many, many layers of compact and fill.

I've just always been nervous building anything on top of a freshly dug excavation.....especially if you were not the one to do the work.\

we all know what happens when they cut a road open to put a water main line in........you get a 2 ft wide 'tire rut' going right down the middle of the road when the asphalt sinks.....now you may have that right in the middle of your wall.
