3 Reasons Why You Can Use Concrete on the Second Floor

A durable, robust, and adaptable building material, concrete can be used in various applications. This material’s incredible durability and strength make it a popular choice on walls and floors. On the other hand, concrete is extremely heavy, leading some people to question whether it is a suitable material for use on the second floor.

You can use concrete on the second floor as it is typically poured thinner on an existing surface to reduce the amount of weight placed on any supporting structures.

Continue reading to learn more about using concrete flooring on the second floor. Using concrete flooring upstairs has several advantages and disadvantages, which I will discuss in detail and what needs to be done before installing concrete flooring.

What should the thickness of a concrete floor on the second floor be?

However, because concrete flooring is a heavy material that requires a strong structure to support it, it has several advantages, including longevity and appearance.

As a result, concrete floors on higher stories are frequently thinner than on lower stories. So how then do they have to be when they’re being poured on the second floor.

A concrete floor on the second story should ideally be 4-6 in (10.16 – 15.24 cm) thick to provide adequate structural support.

However, because of the weight of concrete as a building material, second-story concrete floors are frequently less than 4 in (10.16 cm) thick.

Nonetheless, the greater the thickness of the layer, the more durable the concrete floor.

Second floors made of concrete can be installed as thin as two inches (5.08 cm) in thickness. However, using a thinner layer of concrete will cause the concrete to become more brittle, making it more susceptible to cracking and breaking.

Concrete flooring may not be possible upstairs in some homes due to inadequate structural support, as demonstrated by the above examples.

On the second floor, there are several advantages to using concrete floors.

Concrete is commonly found on many homes’ first and second floors, but concrete flooring is uncommon on the second and third floors.

The popularity of this practice has, however, increased in recent years. So, what is it about concrete floors on the second story of a house that attracts some people?

The following are some of the benefits of having concrete floors on the second floor:


One of the benefits of using concrete for your upstairs flooring is that it is a long-lasting material that will last for years. In addition, concrete can be recycled and re-purposed after a while.

On the other hand, a concrete floor will last for decades with very little maintenance or care once it has been laid down. As a result, you will not require additional materials for repairs or replacement.

Limestone, one of the raw materials used in concrete production, is readily available. The result is that minimal transportation is required to deliver concrete from the source location to your residence.

This helps to reduce the amount of carbon dioxide emitted during transportation.

The production of concrete has the potential to be harmful to the environment. Fortunately, the material’s ever-changing nature makes it environmentally friendly and safe for use in the home.


Concrete is a material that requires little maintenance. It will last for decades following careful pouring and drying with little need for ongoing care and maintenance. All that is required is that you keep your concrete floor clean.

It is critical to understand that thin layers of concrete are more prone to cracking than thick layers.

However, the good news is that cracks can be filled in with new concrete, and the flooring will look and perform as well as new, making concrete flooring both inexpensive and simple to maintain.


Even though concrete flooring is more expensive than alternatives such as laminate flooring, it is a very cost-effective choice.

This is due to the material’s long-lasting nature. Concrete is durable and requires little to no maintenance over a long period.

As a result, you can save a significant amount of money over time and reduce the expenses you would otherwise incur due to repairs, replacements, and maintenance associated with other types of flooring, such as hardwood.


There are numerous design and shape options for concrete flooring on the second floor of your home, which is another advantage of using concrete on the second story of your home.

Concrete can be poured into almost any shape that you can imagine. Additionally, it can be colored by adding the colored powder to the mixture during the mixing process.

When the concrete flooring is wet, it is possible to stamp patterns, designs, and textures into the surface. Stamped concrete is what this is known as, and it provides homeowners with nearly limitless design options.

Using concrete floors on the second floor has several disadvantages.

You may be eager to install concrete flooring in your home now that you know the advantages of using it upstairs.

However, before you start ripping up the flooring upstairs, it’s important to understand that using concrete flooring has some disadvantages, especially on higher floors.

The following are some of the drawbacks of installing concrete floors on the second floor of your home:

A lot of weight

One disadvantage of installing concrete flooring on the second floor of a building is the additional weight to the structure.

Concrete is extremely heavy. The weight of a concrete floor may be too much for your home if it does not have a solid foundation in place, causing serious structural problems.

Some people choose to install thinner layers of concrete flooring to get around this problem. On the other hand, it would make the floor more susceptible to wear.

Because of the lack of structural support in some homes, installing concrete flooring on the second and third stories may not be possible.

The surface that is hard or rough

Perhaps the most significant advantage of concrete is also its most significant disadvantage. It is extremely difficult and demanding.

Falls or slips on concrete floors can be excruciatingly painful, and they come with a higher risk of injury than falls or slips on alternative flooring materials.

Rough concrete surfaces can also pose a risk for skin irritation and scratches. Consequently, installing concrete flooring upstairs may not be a good idea if you have babies, young children, or elderly family members living in your home.

Cracking and abrasive wear are common problems.

While concrete is a long-lasting and durable building material, it is prone to cracking and breaking when exposed to extreme temperatures.

In addition, your concrete flooring will likely crack if your home shifts due to shifting soil, foundation issues, or even earthquakes.

Heat fluctuations can also cause the concrete to expand or contract, resulting in cracks. Even though repairs are usually straightforward, they can still detract from the overall appearance of your home.

Is it possible to put concrete floors over wood?

Concrete flooring is environmentally friendly, long-lasting, aesthetically pleasing, versatile, and offers excellent value for money.

On the other hand, concrete is heavy and requires substantial support to remain stable. So, is it possible to install concrete flooring over existing wooden floors?

Concrete floors can be installed over wood because it requires additional support to remain in place. However, the wood must be at least 34 in (1.9 cm) thick to provide the concrete with sufficient support to remain strong and stable over time.

If possible, check the condition of the wood to ensure that it will not undergo structural changes or deformities, such as when it is exposed to moisture, which could impact the positioning or stability of the concrete floor later on.

Concrete flooring can be installed over various surfaces, including tiled floors and concrete slabs joined together.

It can also be poured into a container and allowed to dry. A variety of support structures may be required depending on the method of installation that is employed.

Concluding Remarks

Concrete floors can be installed on the second floor of your home as long as your home’s support structures are strong enough to withstand the additional weight of the material.

Unfortunately, while concrete flooring is environmentally friendly, long-lasting, and attractive, making concrete is not always environmentally friendly.

Furthermore, because it is a heavy material, some homes may not have enough foundation to support the weight of the material.

Consequently, some people opt to install a thin layer of concrete flooring or forego the material’s use entirely.

Consequently, before installing concrete on the second floor of your home, it is necessary to weigh the advantages and disadvantages of doing so.
