I do construction and a lot of the houses we do have Geothermal piping put in for heating and cooling. They will drill 8 - 10 holes to run the pipe down. There are big piles of whatnot left over by each hole. Mainly rock and soil debris. Do you think this would be good for the garden. I suppose finding out waht kind of rock they are drilling through would help but your basic MO bedrock is what it is whatever that may be. If it would be good I could truckloads of it.
What do you think?
