Interesting, when my son built a house a year ago, he was having trouble getting the contractor to put in the septic system and the general finish grading finished before winter set in. This also included getting the garage floor rough grading done, and graveled. Too late to get the floor poured, it was recommended he wait until spring to pour the garage floor. When the final inspection came the end of Jan., the inspector said "Oh, the approval to move in will not be issued until the garage floor is poured". This came as a surprise, as it was not mentioned before that time. By then, the MN winter was mid-way through its freezing cycle, and the garage floor was frozen solid.
The reason given was "You can't have vehicles parked on the gravel in the garage, because the oil may drip off the engine and contaminate the soil, and get into your well water".
Duh, couldn't help but wonder what was happening when the vehicle was parked outside on the gravel.
After an extension on his building loan, and three months later, finally was able to move into his new house - just because the garage floor wasn't poured.
Maybe there is a law coming down the pike that vehicles won't be allowed to drip any oil on any surface for fear of contamination. Hmmm? /forums/images/graemlins/crazy.gif
