Is there a way to tell if the cracks are caused by geology or if the
driveway was not properly packed before the concrete?



It's probably both. Plus poor drainage.

Most of the time driveway cracks are caused by poor bed-preparation, often
combined with poor drainage (who has ditches on either side of his
driveway?).

Residential driveways basically consist of whatever ground the home-
building equipment drove over while the house was built, plus a couple of
inches of gravel spread around afterwards. And the lawn will be level with
the pavement.

Nobody builds a driveway the way a road is built -- unless he works in
road-construction, and takes two months to prep and build his driveway
(I've seen this done, many times!).



The tennis courts at our recreation department also have some pretty
significant cracks.



Poor drainage and/or poor bed-prep. What's the drainage like? Drainage is
probably more important than bed-prep.
