After discussing the basics of your project, discuss the specific project you are building.

Talk about the foundation’s architectural plans, soil conditions, and structural integrity that need to be reviewed.

Discuss the materials used for construction, including the type of lumber and other building materials.

Be sure to ask your contractor questions if you are unsure about anything related to your project.

Research the best concrete mix for strength and longevity in your climate.

Concrete mixing is a vital step in any construction project, so make sure it’s done right.

The climate and the environment determine the correct concrete mix used.

Choose a mix with enough water to make it work but not so much that it weakens the concrete.

Ensure you use an air-entraining agent that helps create tiny air bubbles in the concrete and strengthens it against freeze-thaw cycles typical in colder climates.

The project you are working on will also determine how much cement and aggregate you will need.

Make sure the mix is proportionate to the amount of work needed, and adjust it according to the climate in which your project is taking place.
