Well I have been referring to this job for a while now. It has been a client of mine for many years. This "company" did this job for $10,000. Customer supplied material. Company supplied the equipment, but not sure who owned it. Job took 10 months. Some weeks they worked 50 hours, others they worked 5. I averaged them at 3 days a week, which is pretty close. Company went bust by the end. It was completed about 18 months ago. There is sagging, heaving, and all around problems. Customer is having trouble selling house in million dollar neighborhood because of work. We are doing a complete rebuild one section at a time. Financially he cant swing more than a section every month or two. When we ripped up the back walk we found it was installed on top of 1/4" dust nothing more. I know the driveway is on top of dust only with varying thickness as they dumped a huge pile then graded it on top of the existing with no prep. I figured these 2 guys where working for $5.20 / hr and commuting from out of state. Enjoy.
