Its food for thought. The drive slopes at 15% towards the garage, so water runs down and flows over the slab. With the pavers out, there is effectively a ditch that diverts the water, but it is at best unsightly. I have seen drain channels formed full width in front of garages and covered with a steel grate. I assume those are custom fabricated. Since I have poured concrete but never done exposed aggregate, this might be a project I just find a good contractor on.
Thanks for your feedback Henry. Aways innovative ideas and good to hear from you.
