| I know I'm not the only one who has to deal with weeds growing between the seams on a driveway. So my question is, if I already have the pressure washer out, any harm in using it to blast away at the weeds? |

| Nope, we do it all the time while cleaning concrete. Just be sure the cement is in good condition. You wouldn't want to blast it if it was deteriorated and crumbling. |

| I have a question about this, are the weeds growing from under the concrete or just from dirt and dust that settles in the cracks? I would be concerned if it was under the concrete that you might have water freeze if it got cold enough and heave the concrete, or crack because of voids under the concrete caused by the water |
