Pictures would help immensely. :)

Hope this helps. Another solution is to have the concrete "blacktopped".

I don't understand what the problem is. If he doesn't like the surface of the driveway then he can have it torn out and replaced with a different surface material (asphalt, pave stones, concrete, etc). It's normal for concrete to have seams between each slab (the second picture).

If you live in a neighborhood with an HOA, you will need to contact them to have their architectural committee to approve of any work on the exterior of your property.

If it's sea salt, your options are limited since the sea isn't going anywhere (rather, rising towards your driveway, if anything), and the salt is perpetually damaging. You could replace your driveway with gravel or pebble, but if it's otherwise fine and just is an aesthetic issue, it might just be a big waste of money.

I was expecting to see huge cracks and possibly crumbled edges!
