How To Level A Concrete Floor That Slopes

Of all the different flooring materials you can use, concrete ranks as one of the most resilient and long-lasting building materials available. However, slopes or depressions can form in areas where moisture gathers, such as a basement or laundry room.

There are many reasons to correct these dips, one of the most convincing being to prevent them from worsening and causing structural issues. Second, if you wish to replace the present concrete surface with new flooring, you’ll need it to be as level as possible.

There are no hard and fast laws or regulations for leveling a floor, making it a popular home renovation project. You may learn all the steps you need to know in our guide, and you can even get help with a market-leading device called “Concrete Leveler” to help you with your concrete leveling operation.

By the end, you’ll see that using self-leveling concrete compounds to fill in low spots and make your existing concrete floor as level as it was before isn’t the most laborious task.

Can Self-Leveling Concrete Be Used On A Slope?

Self-leveling concrete is a viscous polymer-modified concrete. To make a flat and even surface, pour it over the floor like a thick liquid.

It is excellent for flattening old hard floors like concrete, tile before installing new tile or wood flooring.

But just because self-leveling concrete is easier to use doesn’t mean it can’t go wrong.

Here are a few things to be wary of when considering using a self-leveling layer.

  • Self-leveling concrete can lead to eye or skin irritation (burns). Wear safety goggles.
  • Inhaling can lead to coughing or sneezing.
  • Temperature affects how the concrete sets. It needs temperatures between 65 and 80°F.
  • You can only use self-leveling concrete indoors.
  • You can use self-leveling concrete to cover gaps, but it shouldn’t be used on surfaces that slope over 0.5 percent.

Another thing to note is that self-leveling concrete of this type dries quickly, so you have around 20 minutes to work with the product.

Last, self-leveling concrete does not reinforce the existing floor. Therefore, if the subfloor is damaged, the self-leveling concrete will loosen, which leads to damage to any floor on top of it.

What Is The Cheapest Way To Level A Concrete Floor?

If you don’t want to use self-leveling concrete to level a sloped basement floor, discover how to level a concrete floor for the least amount of money.(Learn How To Screw Into Concrete)

Using a particular sand mix to level a concrete floor is cost-effective. This concrete-based mixture will spread across the uneven floor for a consistent finish.

To do so, distribute the sand mixture on the floor until it looks level to the naked eye, wet it down, and let it dry.

Remove sand particles from the top surface with a bristles brush once it has dried.

For the overall cost, this procedure will save you 90 percent. This is a sizeable sum, especially when spread across a wider area. Just check the package label to get the right area coverage, or you could end up with a thin layer that cracks and breaks.

Compare this to other options, and it is easy to see why this is an easy way to get a level surface for your new floor and flooring material.

How Do You Fix Sloped Concrete?

To cut a long story short, there are many homes with a basement that slopes 2” from one end to another.

When searching how to level a sloping concrete floor, a self-leveling compound can be a suitable option for no more than a 1” slope. Can you use multiple layers of self-leveling concrete, or do you need to frame up and pour concrete in sections?

1. Note the areas that are uneven.

  1. A level bar can be used to evaluate if your floor is uneven.
  2. Once you’ve found them, mark them and have them ready to grind.
  3. Using a concrete grinder to grind them down to level the high points.
  4. Gloves and eye protection are required. First, place the machined disc flat against the mark you want to make. Then begin grinding uneven high points from the front to the back.
  5. Grind the area until it is level with the rest of the floor. After you’ve smoothed everything out, vacuum the particles with the shop-vac.

2. Prepare concrete bonding agent.

  1. Dilute the bonding agent before applying it. Follow the manufacturer’s directions for diluting it with water.
  2. Coat the concrete with a concrete bonding agent.
  3. Using a nap roller, apply a layer of bonding adhesive to your basement floor.
  4. On the back of self-stick paper notes, please wait for the adhesive to dry to the point where it is no longer wet but keeps the glue’s stickiness.

3. Get the self-leveling compound ready.

  1. Apply the self-leveling compound to the uneven areas of the floor surface.
  2. Pour the mixture on the floor first.
  3. With a squeegee, spread it out evenly. Because the leveling compound dries rapidly, you must work swiftly. It should begin hardening after 20 minutes after application.
  4. To level the floor, apply only a 1/4-inch layer of compound and let it dry for the period shown by the compound maker.
  5. Drying times are usually less than 48 hours before you can return items to the basement.
  6. When the concrete is dry enough to walk on, you can install tile or another hard-surfaced flooring on top of it.
  7. Before installing moisture-sensitive flooring such as carpet, wait at least 16 hours. Temperature and humidity affect drying time.

Can You Self-Level A Sloping Floor?

Here’s how to level a sloped concrete floor in detail.

1. Identify Cause of Slope

The first step in dealing with a slanted concrete floor is to figure out what’s causing it to fail. This will determine whether the concrete can be restored or if it needs to be completely replaced.

If the concrete slab has sunk or heaved, it is critical to address the root cause of the failure before proceeding. If you don’t address the root of the problem after repairing the concrete slab or floor, you’ll continue to have issues.

2. Inspect the Material Beneath

The first step in repairing concrete floors for a self leveler is to determine what type of material is beneath it.

You may discover vacant space beneath a concrete floor in the ground because of subgrade settlement or expansion. If a frost-sensitive substance is used to support the concrete floor, it will expand and contract. (Learn How To Polish Concrete Countertops)

The new concrete floor will then have a solid foundation on which to load. The carrying capacity of the soils to support the concrete is the most important factor to consider while creating a concrete floor.

You can lay a self leveler on top of an existing floor if the subgrade beneath it has adequate bearing capacity and the concrete is structurally sound and merely needs resurfacing.
This is how you do it:

3. Prepare and Clean

Remove any loose or degraded spots from the surface of the concrete. Remove the baseboards, furniture, appliances, and anything else on or around the floor to accomplish this.

Then, using a professional concrete cleaner, clean the floor to remove any grease and oil stains, dirt, and debris.

The better the old floor is cleaned, the better the concrete leveling compound will stick to it. Use a metal scraper to remove any remaining flaws on the concrete, such as chipped or flaking areas. Vacuum the entire area to finish.

4. Mark Off and Grind Down High Points

Then, using a leveling bar along the floor, identify and mark off the sloped spots. Grind down high points or high areas with a concrete grinder, moving it back and forth until each spot is level with the rest of the floor. Vacuum up any remaining dust and debris.

5. Prepare Bonding Agent

Once the concrete is clean and dry, use a mechanical bonding agent, like steel dowelled in epoxy, to join the two concrete slabs.

6. Prepare Leveling Concrete

Using a mixing drill and the right amount of water, combine the concrete compound until it’s dense and easy to pour.

The thickness will vary depending on the amount of leveling agents you add.

7. Apply the Leveling Concrete

Before you pour the concrete, make sure all drains are covered. Then, with a squeegee, disperse the leveling compound across the existing concrete into the corners and edges where needed.

Use a concrete leveler or leveling bar to ensure you’re leveling the deck mud as you go.

Work swiftly through this phase since the concrete will start to dry in about 20 minutes.

The time it takes for furniture to dry varies depending on the manufacturer, but on average, it takes about 48 hours before it can be moved back onto the floor. (Learn How Many Wheelbarrows In A Yard Of Concrete)
