    We will need a lot more information such as what material your driveway is. Pictures also go a long way Sep 15, 2018 at 15:39
  • What is the intent? Are you trying to slow down the flow or redirect it? Are you intending to make a dam? Aren't you concerned about where the water will go if you restrict flow? Please give more info. Sep 15, 2018 at 23:06

You want to use concrete mix not cement. Cement is more expensive and has nothing to hold it together it will form a block but is much more expensive. I have done this many times over the years. I place the bags tightly together then poke holes in the top of the bags and wet them down this starts the block forming and as time goes on it will become solid. I use the light duty bags as they are cheaper and work fine.
