Gravel or Crushed Concrete for a Driveway?
We're wanting to put in a driveway and were intending to put gravel down as the surface material (we are not planning to pave over it). A friend told us that crushed concrete (which is about the same price) is better because it packs harder. Would crushed concrete be a good or better choice for a driveway surface given that it is the same price as gravel? We're also putting in a retaining wall and will use the leftover gravel or crushed concrete to fill in behind the wall. Would crushed concrete be a good choice for packing behind garden wall block? We want to allow for drainage behind the wall through the gravel so I am concerned that crushed concrete may pack too tightly for that. Thanks for the help!
