The big dig

Concrete removal was the most expensive part of this project. A simple 9'x15' section of driveway was to be broken up and taken away. However, a utility trench was needed to cross under the driveway for a drain pipe, an irrigation pipe, and an electrical conduit. Concrete cutting was required, not just concrete removal. The trench was eventually covered with paver bricks dry-grouted with crushed granite for appropriate semi-permanence.



Lessons learned
Hiring the concrete-removal contractor should have been better planned. I had to schedule them within just a few days due to friends and hired labor helping me on a specified day. Contractors with diamond-tipped concrete saws were important, too, not just concrete haulers (guys that can just swing a sledge hammer and drive a dumptruck). In addition to the 135 sq ft section and trench, I asked for a 4" hole at the curb (for a drain outlet) and two 14" diameter borings elsewhere (for future post footings).

Concrete removal cost: $800. Ouch.
