When you think about cement, you probably think about its strength and durability. But did you know that cement, as tough as it is, is still vulnerable to water damage? Yes, even cement can get damaged by moisture over time. Waterproofing your cement is the best way to ensure it stays strong and long-lasting.
In this guide, we’ll walk you through why cement waterproofing is necessary, how it works, and the top methods and materials you can use. Whether you’re working on a basement, patio, or any structure made from cement, this article will give you everything you need to know.
So, what exactly is cement waterproofing, and why is it so important? Let’s dive right in!
What is Cement Waterproofing and Why Is It Important?
Waterproofing cement is the process of making it resistant to water. When cement is exposed to water over time, it can weaken and crack. This can lead to bigger problems like mold growth, structural damage, and costly repairs. Essentially, waterproofing helps protect your investment in cement structures and ensures they last longer.
But why does cement need waterproofing in the first place? It’s because cement is porous, meaning it can absorb water. The water can seep into the pores, leading to cracks, which can be expanded by freezing in cold weather. And that’s where waterproofing comes in—it helps seal those pores, preventing water from entering and causing damage.
How Does Waterproofing Work on Cement?
Waterproofing works by creating a protective layer on the cement surface. This layer prevents water from penetrating and protects against moisture damage. Depending on the method you choose, waterproofing can work by either repelling water or by chemically bonding with the cement to make it water-resistant.
When applied correctly, waterproofing makes your cement more resistant to wear and tear caused by water. This can be crucial in areas that are regularly exposed to moisture, such as basements, bathrooms, and outdoor structures.
What Are the Best Methods for Waterproofing Cement?
Now that we know what waterproofing is, let’s talk about the best ways to achieve it. There are several methods you can use, depending on your needs and the specific cement surface you’re working with. Here are the top methods:
1. Waterproofing with Sealers
One of the most common methods for waterproofing cement is using a concrete sealer. Sealers are easy to apply and provide a long-lasting barrier that protects cement from water damage. There are two main types of sealers you can choose from:
- Penetrating Sealers: These sealers penetrate deep into the concrete, blocking the pores from the inside. This method is great for surfaces that will be exposed to heavy moisture, like basements or patios.
- Surface Sealers: These create a protective coating on the surface of the concrete. While they are great for protecting against surface water, they are not as effective at blocking moisture that seeps deep into the cement.
2. Waterproofing with Membranes
Another effective way to waterproof cement is by using a membrane. Membranes are typically used in areas that are heavily exposed to water, like foundation walls and rooftops. These membranes come in liquid, sheet, or spray form and create a waterproof barrier that prevents water from passing through.
There are two types of waterproofing membranes:
- Bituminous Membranes: These are made from asphalt-based materials and are great for protecting foundations and concrete surfaces against moisture.
- Polyurethane Membranes: These are flexible and are great for outdoor applications, such as waterproofing terraces or balconies.
3. Cementitious Waterproofing
Cementitious waterproofing is a simple and cost-effective method that involves applying a layer of cement-based waterproofing material on the surface. This material creates a thick coating that blocks water from seeping through.
This method is perfect for areas that are not exposed to constant water pressure, like bathrooms or interior walls. It’s easy to apply and can be used both indoors and outdoors.
What Are the Top Products for Cement Waterproofing?
Choosing the right product for waterproofing cement can make a huge difference in the effectiveness of the process. Here are some of the top products that can help you achieve the best waterproofing results:
1. Drylok Concrete Floor and Wall Waterproofer
Drylok is a popular brand known for its concrete waterproofing products. Its concrete floor and wall waterproofer are designed to protect against leaks, seepage, and moisture damage. It’s easy to apply and perfect for basements and crawl spaces.
2. Thoroseal Waterproofer
Thoroseal is a cement-based waterproofing compound that is perfect for sealing cracks and preventing water penetration. It’s often used for foundation walls, concrete floors, and basements.
3. RedGard Waterproofing and Crack Prevention Membrane
RedGard is another top choice for cement waterproofing. It’s a liquid membrane that not only waterproofs but also prevents cracks in your cement. It’s easy to apply and can be used on both interior and exterior surfaces.
Where Should You Apply Waterproofing to Cement?
Waterproofing should be applied to any cement structure that is regularly exposed to water. This includes:
- Basements: Since basements are often below ground level, they are more susceptible to water seepage. Waterproofing your basement can prevent mold, mildew, and structural damage.
- Bathrooms and Kitchens: These areas are frequently exposed to water, and waterproofing helps protect against leaks and water damage.
- Outdoor Surfaces: If you have a patio, driveway, or garden path made of cement, waterproofing will protect it from weather-related wear and tear, such as rain, snow, and ice.
- Foundations: Waterproofing the foundation is crucial to ensure your building stays safe and dry.
How Long Does Cement Waterproofing Last?
The longevity of waterproofing depends on several factors, including the type of waterproofing method used and the conditions the cement is exposed to. Generally, waterproofing can last anywhere from 5 to 10 years. However, high-traffic areas or outdoor surfaces exposed to harsh weather conditions may need to be reapplied sooner.

FAQs About Cement Waterproofing
1. How long does cement waterproofing take to apply?
Most waterproofing products take a few hours to apply, but it’s important to let the cement dry completely before applying the second coat (if needed). Always check the manufacturer’s instructions for specific drying times.
2. Can waterproofing be applied in cold weather?
It’s best to avoid applying waterproofing products in freezing temperatures, as this can affect the product’s ability to bond with the cement.
3. Is waterproofing necessary for every cement surface?
Not all cement surfaces need waterproofing, but it’s a good idea for areas exposed to moisture or high humidity, such as basements, bathrooms, and outdoor patios.
4. How can I tell if my cement needs waterproofing?
If your cement surface is showing signs of cracks, stains, or water seepage, it may be time to apply a waterproofing solution.

Many waterproofing products are DIY-friendly and can be applied with basic tools. However, for larger projects or complicated areas like foundation walls, it’s a good idea to consult a professional.
6. Does cement waterproofing prevent mold?
Yes, waterproofing can help prevent the growth of mold and mildew by keeping moisture out of your cement surfaces.
7. Is waterproofing the same as sealing?
Not exactly. While sealing and waterproofing both aim to protect cement, waterproofing is specifically focused on preventing water penetration, whereas sealing may only offer surface protection.
8. How often should I reapply waterproofing?
Depending on the product used and the conditions, you may need to reapply waterproofing every 5 to 10 years.
9. What is the difference between penetrating and surface sealers?
Penetrating sealers soak into the cement to block water from within, while surface sealers create a barrier on top to prevent water from sitting on the surface.
