My PM had connected with CompacSol to get soil worked on due to instability of soil. The one in Toronto was not available so I had to go through this company (wasn't really given the choice as there were only two). They came by with their machines a couple weeks after I decided to use them. They had to bring a lot more stones. I definitely did not expect to pay so much for the service, but it turned out they could have charged a lot more because the surface area that they had to cover were more than the estimated coverage. They said they were doing us a "favour". They had to excavate deeper and wider to ensure the passing of the test before the foundation was poured. This is a father and son company and they would take turns coming in to Ottawa to supervise the work. They took pictures for their own portfolio, as well. After $35000, the area was ready for the foundation! The son said he'd come to check it out after a year, but it's been two years and I have no seen him just yet. Time will tell if the job they did was a good one.
