We built a house in our public school system and have done several over last 20 years. The latest had a fairly sharp turn for a side entrance garage. According to those present the driveway is generally correct. There are tire marks from owners car partailly caused from the sharp turns I think. However, these marks apprear in several places. We have explained according to those in the industry the surface is fairly rough reflecting current concrete specifications in Fairfax County, Virginia. Therefore, what else can we do for the homeowner? Any ideas are welcome. Jim.
