Browse Forums Paving & Concreting 1 Oct 10, 2020 11:15 am I have discovered a concrete slab under the pavers on my driveway which consists of a 3-4 inch solid base and a softer brittle 1/2 inch section on top. I was forced to remove a cracking section of the concrete shown in the second photo. Some of the upper layer has broken away and some sections aren't level. I've been reusing the pavers out back and wanted to buy some new pavers to start parallel with the boundary and in a different direction to the previous layout. Question is: Can I create a gravel base layer around this section, compact and screed with a sand layer to merge with the existing concrete base. I have a lower end high yield property so I could deal with something functional. Second option is less glamorous and laborious, but will save me $1500-2000 to rip out all of the concrete (of which I'm over) and wack down some driveway gravel. It certainly won't be inconsistent with the neighborhood. The downside for this option is gravel run off onto the concrete base to the back.
