if there are spaces between your blocks, then weed seeds are blowing in and getting caught there and rooting..... and you can't stop that.... pull up what's growing  or whatever, but then get some Preen down in those cracks to stop seeds from sprouting.... 

and, with Nature in control, NOTHING lasts FOREVER... you have to apply and yank over and over again.... or get a solid concrete driveway!....

here's info and names on the Sodium Chlorate..

and like was said, be really careful with it..... really careful.... it 'has a soil sterilizer effect'.....and it's explosive in the dry state.....

You can use a type of soil sterilant that will kill everything for up to a year.  You have to be careful of any run off as it will kill and prevent any growth from occurring for a year.

it's not the herbicide but the kind of underlay you use under the block paving (it prevents the shoots from coming up from the ground)

Sodium chlorate   ,,, but don't let it near anything you do want to grow ,,, It tends to creep .
