I have to have my septic system inspected prior to selling the home. The inspector needs to take 2 soil borings. Has anyone heard of using a charcoal fire to thaw the frozen ground? I live in Minnesota and the frost is probably down several feet.
If you can get an old tractor rim-the ones with no center-they work great, build your fire inside the ring and it conentrates the heat into that area. You could do the same with the charcoal and an old tire rim too I guess. And if you have lots of time on your hands a simple propane handheld torch that is hooked to a 20lb or 100lb tank will do the trick also.
