So because the dimensions changed from 147x168 to 145x186 that changes the yards of base I need. I'm thinking the incorrect dimensions were from a moment of dyslexia. So I need 416 yards for a depth of 5 inches. This guy says his dirt is verified 20% sand 60% clay and will compact. He is supplying the dirt from his own 45 acres and is charging me $4 a yard instead of $20 a yard at the local material places. So $5600 for the dirt and loads delivered. For the same dirt at the material yard that would be over $8,000. I'm trying to get the price rounded to $7,000 but will have to wait until I get my tax return. Will shred and chemically treat in the mean time. Can you tell me more about the screenings and density? I was wondering what screened dirt was.
