Concrete Leveling questions, answered by experts

You should water new concrete by spraying it five to 10 times per day for the first seven days. This process of moist curing allows the concrete to become as strong as possible to prevent cracks and weak concrete. Moist-cured concrete is 50% stronger than concrete that was not sprayed with water during the first week. The only exception is if you pour concrete in the winter. Then, spraying with water is not recommended.

Concrete should not be poured directly over grass, as this will impede the necessary tension of the concrete. Grass and soil can draw in moisture, leading to potential cracking. For a solid, lasting foundation, the area must be flat, firm, and completely dry.

Concrete homes have better fire resistance because this material is highly resistant to fire and heat. But any paint, siding, windows, roofing, or other materials on a concrete home may still be flammable. Never try to stay in a building with a large, active fire or a wildfire approaching because this can still be deadly. However, building a fireproof home with concrete can better protect the structure against total destruction.

If the moisture level in your concrete flooring is higher than what is acceptable for your primer or flooring materials, then you are looking at dealing with major flooring issues down the road. From mold and mildew, to warping, buckling, bubbling, and soft spots, you could see a wide range of moisture-induced problems.

These issues can affect not just your flooring but your foundation too. That is why measuring moisture in concrete is so important before starting a project.

The concrete that likely already makes up your garage floor is the longest-lasting garage floor material, although you can treat it with a variety of coverings to improve its durability. Epoxy is one of the most popular options, as it’s relatively affordable, adds strength to the floor, helps prevent staining and physical damage, and even improves the resistance to water intrusion. Other popular options for durable floor coverings include rubber, an aspartic coating, and vinyl.
