Concrete Info |
| 1. To begin - make plans! |
|
A project made with concrete is so permanent that it will become a lasting monument to your lack of planning! Make sure you know exactly what you're going to do and who's going to help you before the concrete arrives! Stake out the area you will cover. Make sure that water will drain away from buildings and that you do not interfere with tree roots! Remove grass, level your ground (use a carpenter's level), fill in the spots and then pack and dampen the area. |

| 2. Forms | |
|
Use 2" x 4" planks set on edge. Hold the 2" x 4" in place with stakes driven into the ground every 18 inches. The stakes must be on the outside of the forms and must be even with the top of the forms.
OPTION: You can nail together a grid-work of permanent dividers and place them inside your forms for decorative effect. These dividers must be rot resistant cedar or redwood and nails must extend from them to anchor them in the concrete. |

| 3. Gather your tools | |
|
Most of these tools are available for rent. |
|
| 4. Make sure you have several people to help you (at least three people for three yards or less of concrete)! | |
|
Pour concrete out of the trailer or wheelbarrow. Begin at the far end of the forms and dump each load close to the last. Use square nose shovels and rakes to spread the concrete evenly to top of the forms. |

7. Run an edger lightly around once following the tamping to establish a grove. This will simplify final edging. |
|
|
|
10. Use the edger again following the hand float to produce a rounded edge that will not chip easily when forms are removed. |

Concrete Facts: |
|
|
Too much water weakens the Concrete causing sandy surfaces, peeling and chipping. Too little moisture causes the Concrete to cure too fast and will result in wind check and cracking. Concrete will reach half it's strength in 10 days and it's full strength in 27 days. Hot days or windy days can affect the finish of your job. |
