What are some possible errors with doing concrete?

Answer 1

Possible errors that can occur with concrete jobs include:

1. Failure to predict weather; doing it when too cold or raining.
2. Failure to use the correct tools.
3. Failure to plan the work and materials.
4. Failure to correctly measure Length x Width x Depth to mix or order the correct amount for concrete.
5. Failure to properly measure the bed, and make earth bed level.
6. Failure to frame and keep the bed's sides perfectly aligned (use marked string to snap a line).
7. Failure to prepare the bed properly, including wire mesh bed, side framing.
8. Failure to mix the correct amounts of concrete, sand, water, and pebbles if desired.
9. Failure to use the correct amount of water, or letting the mix sit not long enough or too long.
10. Failure to properly stir the concrete mix, including avoiding introducing air bubbles.
11. Failure to work concrete mix into all corners and tap it down into the mesh flooring.
12. Failure to level the concrete mix once it is laid.
13. Failure to add texture to top surface to add traction (for slippery weather).
14. Failure to keep kids and pets away---nothing like a foot-paw print to mess up a sidewalk.
15. Failure to cover if it starts to rain.
16. Failure to let the concrete set and dry completely before walking on it.
17. Failure to unlock an alternate door before you start--now you can't get into the house.
