the driveway moves one way the street another. sadly it cant be fixed
permanetely.

the black caulk like stuff is the best, but below freezing it too may
crack/

I just seal my driveway every couple years so water cant get in the
crack and make it worse.......

its like wrinkled skin you can pretty it up but cant do much about the
underlying cause


reportedly hot tar works better but i dont knoiw where to buy it or how
to handle it properly, like heating it.

some stuff isnt worht worrying about
