Concrete Leveling questions, answered by experts

While you shouldn’t use thinset mortar on its own as a floor leveler, it can work alongside other products to help level floors. For instance, you could start with a self-leveling compound, let that dry, then apply backer board with thinset mortar to help fully even out the floors ahead of laying tile.

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.

Yes, you can pour concrete if it rained the day before, but you’ll need to drain the construction site to ensure there isn’t standing water where your slab will sit. You might need to manually remove any puddles and set up drainage on your site to dry it before pouring. Moist soil won’t be an issue, but standing water will throw off your concrete mix ratios. Additionally, ensure there isn’t more rain expected in the near future before you pour.

DIY is possible for small jobs, but professionals ensure durability, proper grading, and compliance with safety codes.

Yes, you can drive on concrete after seven days. While doing so, take extra care around the edges of the freshly poured concrete surface, as these areas may not be as strong as the main concrete surface. You should also avoid driving heavy trucks and machinery on new concrete until it’s fully cured, 28 days after it’s poured.
