I've been doing a lot of digging lately. I charge $30 per hour for it. I'd like more, but work has been slack and I enjoy being paid to go on subterranean treasure hunts.
My property contains no clay. I need clay for many things I want to build. Most houses in the
city have clay against their lower foundation walls. When drains are installed, it needs to come out and then it needs to be trucked away. Jobs like this produce large amounts of clay, stone, rock, soil and clay tile. I can use all of these things, and make a buck in the process.
The job I'm working on today has produced about 50 ft of nice thick walled tile that I will use as flue material for the bench or Trombe wall. My demolition work provides fire brick and high temperature flues for areas nearer the fire.
This is the first time that I've sought this sort of work. I don't own an excavator or a big truck. There are a hundred guys who do own those things in my area. They're a phone call away. I am going to seek out a few and in some cases, let them contract the job, with the stipulation that I am hired for all of the tough manual bits and to install tile etc. I will have first dibs on anything useful that comes out of the ground.
Photos --- I got about 45 of these tile on my current job. This one is 65 miles from my land, so I'll give away a couple tons of perfect black loam. The remainder will go to a facility that sifted and crushes materials. They'll get a few tons of soil and rock.
