Concrete flooring is one of the best floor coverings for wet areas.
It is inherently resistant to water penetration when properly installed. It can withstand water exposure without deteriorating, making it suitable for areas like bathrooms, kitchens, basements, laundry areas, and outdoor spaces
Besides, properly cured and installed concrete floors have a low water-retention rate. This helps in preventing water from penetrating and seeping through the floor.
For this reason, concrete floors can be used even in areas where there is high spillage or stagnant pools of water.

Reasons why concrete flooring is excellent for wet areas:
Low Porosity:
Concrete is a relatively low-porosity material, meaning it has tiny gaps or pores that limit the passage of water and other liquids. This inherent characteristic makes concrete naturally resistant to water absorption.
As a result, it can withstand exposure to moisture without deteriorating, unlike materials like wood, which can swell, warp, or rot when in contact with water.
Water Resistance:
Due to its low porosity, concrete exhibits water resistance, preventing water from penetrating its surface.
When properly sealed, concrete becomes even more impermeable, reducing the risk of moisture-related issues, such as mold, mildew, and water damage.
Durability:
Concrete is renowned for its strength and durability.
When properly installed and cured, it can withstand the rigors of wet environments, including exposure to water, humidity, and occasional spills.
Its robust nature ensures that it remains stable and intact over time, even in areas where moisture is a constant presence.
This is unlike other types of flooring like laminate floor which peels when exposed to water.
Mold and Mildew Resistance:
Because concrete is not an organic material and does not contain cellulose or other nutrients that support mold and mildew growth, it naturally inhibits the proliferation of these microorganisms.
This property is particularly beneficial in wet areas where damp conditions can encourage mold and mildew development on more susceptible flooring materials.
Easy to Clean:
Concrete floors are relatively easy to clean, especially when they are sealed with an appropriate surface treatment.
Regular cleaning with mild soap and water is usually sufficient to maintain the floor’s appearance and hygiene in wet areas.
Slip Resistance:
Concrete flooring can be finished with various textures or coatings to enhance slip resistance. This is a crucial safety feature in wet areas, where the risk of slips and falls due to water on the floor is higher.
Versatility:
Concrete offers a wide range of design possibilities, allowing for various finishes, colors, and patterns.
It can be stained, colored, stamped, or polished to achieve the desired aesthetic, making it suitable for both functional and visually appealing wet area applications.
Longevity:
Concrete is a durable material with a long lifespan.
When properly installed and maintained, concrete floors can endure heavy foot traffic and wear over time, making them a cost-effective flooring choice for wet areas.
Low Maintenance:
Concrete flooring requires minimal maintenance, especially when compared to some other flooring materials.
Properly sealed concrete surfaces resist staining and are easy to clean, reducing the need for frequent and intensive maintenance routines.
Factors to consider when deciding if concrete flooring is a good option for wet areas:
Concrete can be a suitable choice for wet or damp areas, but it depends on the specific application and the level of water exposure the concrete will experience.
Consider these factors before deciding to install concrete flooring in wet or damp areas
Sealing and Waterproofing:
Untreated concrete is porous and can absorb water, leading to potential issues like cracking, efflorescence (white mineral deposits), and mold growth. However, concrete can be sealed and waterproofed to reduce its porosity and enhance its water resistance.
Properly sealed concrete can withstand moderate water exposure and is commonly used in basements, garages, and other areas with occasional dampness.
Slope and Drainage:
Proper slope and drainage are essential considerations when using concrete in wet areas. Ensuring that water flows away from the concrete surface and is properly directed to drainage systems can help prevent water pooling and potential damage.
Slip Resistance:
Smooth concrete surfaces can be slippery when wet. If slip resistance is a concern, especially in outdoor areas or pool decks, it is essential to use textured or stamped concrete to improve traction.
Freeze-Thaw Resistance:
In regions with freezing temperatures, concrete used in outdoor wet areas should have good freeze-thaw resistance. The concrete mix and installation should be designed to withstand the expansion and contraction caused by freezing and thawing cycles.
Precautions for Constant Submersion:
While concrete can handle occasional wet conditions, it may not be the best choice for areas with constant submersion, such as swimming pools or fountains. In such cases, specialized waterproofing systems and coatings may be required.
However, for areas with continuous water exposure, alternative materials like ceramic or porcelain tiles, natural stone, or waterproof vinyl flooring may be more appropriate.
Always consider the specific needs of the area and consult with a professional contractor to ensure the best choice for your particular situation.
Can water get through a concrete floor?
No, water cannot get through a concrete floor since it is porous. In most cases, water cannot pass through a properly poured and sealed concrete floor. Concrete has a relatively low water absorption rate due to its compact structure and lack of interconnected pores. As a result, it provides good water resistance and can withstand exposure to water without significant issues.
Nevertheless, although concrete has a low porosity, it is not entirely impermeable. The concrete floor allows water to go through if it is not properly installed and sealed.
Bad quality of concrete mixture and aggregate and poor curing can result to cracks and voids. These cracks lower the concrete floor’s ability to resist water.
If dealing with such cracks after a poor concrete installation, you can use concrete surface waterproofing products such as the ;
- Drylok Extreme Masonry Waterproofer
- Liquid Rubber Foundation Sealant/Basement Coating
- HydroHalt Water and Vapor Barrier Membrane (5 gal)
- Quikrete Waterproofing Sealer
- Krystol T1 Surface-Applied Crystalline Waterproofing Application
Besides, over time, concrete may also develop cracks due to settlement, shrinkage or external stress hence allowing water to seep through.
To maintain the water resistance of a concrete floor and prevent water from passing through, proper installation and sealing are critical.
Applying a suitable sealant or coating can enhance the concrete’s impermeability and protect it from moisture penetration. Regular maintenance and timely repairs of any cracks or damage can also help preserve the water-resistant properties of a concrete floor.
In wet areas or areas with high water exposure, such as bathrooms or kitchens, it’s essential to ensure that the concrete floor is well-sealed and adequately maintained to prevent any potential water-related issues.
Additionally, the use of water-resistant membranes or moisture barriers beneath the concrete floor can provide an extra layer of protection against water intrusion
Can I have a wet room with a concrete floor?
Yes, you can have a wet room with a concrete floor. In fact, concrete flooring is an excellent choice for wet rooms due to its inherent properties that make it well-suited for areas with water exposure.
A wet room is a bathroom or shower area where the entire space is designed to be waterproof, without the need for a separate shower enclosure or bathtub. The entire floor and walls are typically covered with waterproof materials to allow for direct water flow and drainage.
Concrete is a durable material that can withstand the constant presence of water and moisture without deteriorating. It can endure the stresses associated with wet rooms, including regular water splashes and high humidity.
Besides, concrete floors in wet rooms are relatively easy to maintain. Regular cleaning with mild soap and water is usually sufficient to keep them in good condition.
In addition, concrete can be finished with various textures or coatings to enhance slip resistance. This is especially important in wet rooms to ensure safety and prevent slips and falls on wet surfaces
Are concrete floors slippery when wet?
Concrete floors can become slippery when wet, especially if they have a smooth or polished surface.
The slipperiness of a concrete floor when wet depends on several factors, including the texture, surface treatment, and the presence of any contaminants. Let’s explore these factors:
Texture:
The texture of the concrete surface plays a significant role in its slip resistance. A rough or textured concrete surface will generally provide better traction, reducing the risk of slips when wet.
On the other hand, a smooth or polished concrete surface may become more slippery when water is present.
Surface Treatment:
The type of surface treatment or coating applied to the concrete can affect its slip resistance.
Some sealants or coatings may enhance the concrete’s slip resistance, while others may make it more slippery when wet. It’s essential to choose the right surface treatment based on the intended use and environmental conditions.
Contaminants:
When water is present on a concrete floor, it can interact with various contaminants like dust, oil, grease, or soap residue, making the surface more slippery.
The presence of these substances can reduce the floor’s grip and increase the likelihood of slips and falls.
To improve the slip resistance of a concrete floor, especially in wet areas, you can take the following measures:
- Textured Finishes: Consider using a textured finish or adding aggregates to the concrete mix during installation to create a rougher surface that enhances slip resistance.
- Slip-Resistant Coatings: Apply slip-resistant coatings or treatments specifically designed to improve traction on concrete surfaces.
- Regular Cleaning: Keep the concrete floor clean to prevent the accumulation of contaminants that could make it slippery.
- Floor Mats or Rugs: Place floor mats or rugs with slip-resistant backing in areas prone to getting wet, such as entryways or bathroom floors.
- Warning Signs: In commercial or public spaces, consider placing warning signs to alert people of potential slippery surfaces when the floor is wet.
Is polished concrete good for wet areas?
Polished concrete can be suitable for wet areas under certain conditions, but it may not be the most ideal choice for all wet environments.
Polished concrete is a popular flooring option known for its glossy, smooth, and visually appealing surface. Its suitability for wet areas depends on various factors, including the level of slip resistance, maintenance, and the type of sealer used.
Slip Resistance:
One potential concern with polished concrete in wet areas is its slipperiness when water is present. The smooth, reflective surface of polished concrete can become slippery, especially if the floor is wet.
To address this, it’s essential to consider adding slip-resistant additives or textures to the polished surface during the finishing process. These measures can improve traction and reduce the risk of slips and falls.
Sealing:
Polished concrete floors need to be adequately sealed to maintain their appearance and protect them from water and moisture.
Choosing the right sealer is crucial for wet areas to ensure water resistance and prevent water from seeping into the concrete and causing damage.
Maintenance:
While polished concrete is generally easy to maintain, regular cleaning is essential in wet areas to prevent the buildup of contaminants that may affect slip resistance.
It’s important to use appropriate cleaning products that won’t compromise the floor’s polished finish or alter the surface’s slip-resistant qualities.
Indoor vs. Outdoor Applications:
The suitability of polished concrete for wet areas can differ between indoor and outdoor environments. In outdoor settings, factors like weather conditions and exposure to rain can impact the floor’s performance and slip resistance.
Alternative Finishes:
In wet areas where slip resistance is a top concern, you may want to explore alternative concrete finishes, such as broom-finished or textured concrete.
These finishes offer better traction under wet conditions and are often preferred for outdoor areas or spaces where water exposure is significant.
