Sometime after we moved in, they paved our walk. In the middle of the walk was a drain. The walk sank and the drain was floating above the path and was less than useful. We also have a low point in our driveway, so I decided the best way to remedy this was to get someone to dig up the asphault walk and for me to dig out the drain, replace it with a lower one and replace the walk with pavers.
This became a WHOLE lot more expensive than I had imagined. But I got it done, and while I was sore and discouraged, so far it seems to have come out well enough. Time will tell if I've bad the base stable enough and if the issue where the walk is now a little low compared to the stairs will be annoying.
I learned there is this new cool paver base stuff that saved me digging out and laying down 4-5" of rock base. I also tried using the polymetric sand for the joints. I'm also really happy with the stones I choose even though they were quite expensive and I was forced to buy way more than I needed. Getting the curve was harder than I had imagined to, but I did get away with not having to make any cuts. I did chip of one corner to fill a hole.
