It seems more and more homeowners are interested in houses with pervious concrete driveways. I can't blame them -- pervious concrete driveways look beautiful, drain water, and help prevent downstream runoff issues.
However, plain concrete driveway construction in new homes is often the lowest quality of construction you'll find. So, I'd be extra cautious about buying a house with a pervious concrete driveway. If I was in the market for a newly built home (with a pervious concrete driveway), to ensure the driveway I'm about to buy is sound, I'd probably ask the builder the following questions:
1) Was the pervious concrete contractor certified as an Installer or Craftsman through the NRMCA's Pervious Concrete Certification program? (The answer I'd be looking for is 'Yes')
2) When was the driveway built? (Ideally more than 28 days ago so it had time to cure)
3) How long was the driveway cured? (If the answer is anything less than 7 days, I'd be concerned)
4) If the driveway fails during the warranty period, what repair technique will you use? (As of today, the only known repair technique for pervious is full-depth removal and replacement)
5) Has traffic been allowed on the driveway? (Homebuilders try to keep traffic off of their driveways to keep them looking nice, however, I'd like to see how the driveway held up under some traffic)
In addition to hearing the correct answers to these questions, I'd walk to driveway to look for signs of raveling or sealing.
Pervious concrete, when done correctly, can make a beautiful driveway. This is not something most homeowners or aveage concrete contractors can do. Having a qualified, knowledgeable contractor is key to making a beautiful pervious concrete driveway that lasts.
