Converyor belts for basement dirt removl
I am digging out a basement for an underpinning project. So far I've been having the dirt taken out by wheelbarrow. I need to remove ~60 cubic yards. So far I've removed ~30... although that is after excavation so figure on a fluff factor of 20% and maybe it is more like 24 cy.
The basement is more of a ground level suite only a little bit lower than grade.
Has anyone used conveyor belts for this process? What is the general strategy for conveyor belt removal?
I've been using 12cy and 7cy bins, once mostly full I have a wooden ramp built to continue loading the bins till full.
Most of the dirt is hardpan so I've been jackhammering it with a 65lbs demo hammer and a shovel blade. Seems like a tonne of work so I am wondering what other people do in this scenario.
Before you ask, I can't raise the house as the exterior is brick veneer. The slab needs to be replace (no vb, no gravel, 1/2" in most places), the main sewer line needs to be replaced - original cast iron 1925ish - really just to be lowered. There are also height bylaw restrictions.
The soil is glacial till - mainly sand, some rock and if you do a suspension test it looks like a glacial river (rock flour coloring the water).
