Hello there
The cheapest way to level a concrete floor is to use a specialized sand mix.
This sand mix is 90% more affordable than self-leveling concrete while producing similar results.
To do this, you will spread the sand mix across the top, spray it with water, and then let it dry.

When finding out how to level an uneven concrete floor, it’s important to avoid using a costly option such as self-leveling concrete.
Yes, self-leveling concrete works but it also costs too much.
Most people are on a tight budget and this is an expense they don’t want on their shoulders. As a result, it’s time to look at finding a cheaper alternative for leveling a concrete floor.
The cheapest way to level a concrete floor will depend on the size of the area that needs to be leveled, the severity of the unevenness, and the type of finish you are looking to achieve. Here are some options:
Self-leveling compound: This is a popular and affordable option for leveling small to medium-sized concrete floors. Self-leveling compounds are easy to use and can be poured directly onto the floor, then spread out using a trowel or roller. They typically dry quickly and create a smooth, level surface.
Concrete overlay: If the floor is severely uneven, you may need to apply a thin layer of concrete over the existing surface to level it out. While this may be more labor-intensive than using a self-leveling compound, it can be a cost-effective solution if you are planning to cover the floor with carpet, tile, or another type of flooring.
Grinding: If the unevenness is caused by bumps or ridges in the concrete, you may be able to grind them down using a concrete grinder. This is a relatively inexpensive option, but it can be time-consuming and may not work for larger areas or deeper ridges.
Patching: If the unevenness is limited to small areas, you may be able to patch them with a concrete patching compound. This is a low-cost option that can be effective for small depressions or cracks in the concrete.
It's important to note that each of these methods has its advantages and disadvantages, and the best option will depend on the specific circumstances of your project
