  • Most residential concrete is poured at 3.5″ thick (actual thickness of a 2×4)
  • Commercial driveways are usually 5.5″ thick (actual thickness of a 2×6)
  • Commonly use 5 or 6 sack mixes (5 or 6 sacks of cement per cubic yard)

Rock or Mulch Ground Covers

  • Normally laid 2 to 3 inches thick to prevent weed growth. Ideally over a commercial  grade weed fabric
  • When using a course gravel 1″ or more, consider putting a layer of smaller gravel down, then overlay a layer of the coarse gravel for the final texture. The smaller gravel will provide superior coverage, then the larger gravel provides the desired texture.

Bags are usually 30 to 40 per cubic yard based on 120 pounds per cubic foot for concrete, gravel, etc. (heavy materials).
