Concrete waterproofing has become more common for all types of construction projects involving the use of concrete. Foundations, driveways, patios, fences, and other concrete structures may last longer if you include the extra step of waterproofing. Explore the top five reasons to waterproof concrete.
1. Increase the Life of Concrete Structures
The main reason to waterproof a concrete structure is to increase its life. Concrete structures may last 50 to 100 years or longer. However, water gradually damages concrete. Areas exposed to more water may not last as long.
A concrete basement floor can last more than a century, but a sidewalk that receives frequent wear and tear may last closer to 50 years.
Concrete is a mixture of sand, gravel, cement, and water. The rock-like structure is porous, resembling a hard sponge. The pores trap water and debris that gradually break down the concrete.
Along with creating an unattractive appearance, the deterioration can weaken the structural integrity of concrete projects. A porch may eventually crack. Cinder block foundation walls may become unstable.
2. Prevent Mould and Mildew
Concrete waterproofing helps prevent the growth of mould and mildew. You can keep mould and algae from penetrating the basement walls and floors or covering concrete porches.
You may notice that concrete porches tend to develop dark patches over time. The dark patches occur due to frequent exposure to rain and the presence of dirt. The rain and dirt that do not run off the side of the porch promote mould and algae growth.
Mould and algae can further promote the deterioration of your concrete structures. It also creates an unattractive appearance that can take away from the curb appeal of your property.
Sealing the concrete with a waterproof layer helps repel rainwater. You can keep porches and walkways free of unsightly growth and easily sweep away dirt and debris.
3. Easier Maintenance and Cleanup
Maintaining and cleaning a waterproofed concrete surface is easier. The surface is less porous. Water and cleaning liquids roll across the surface instead of getting trapped in the pores.
Outdoor concrete construction projects typically have a slight angle to promote water runoff. The water should travel toward one side of the porch, walkway, or stairs instead of pooling in place. However, without waterproofing, water can still collect in pockets and pores on the surface.
Waterproofing creates a smooth surface that you can easily clean after a heavy rain or snowstorm. Keeping your outdoor concrete areas free of water and snow further increases their longevity.
4. Increase the Value of the Property
Certain types of waterproofing may increase the value of your property. For example, applying a waterproof coating to a concrete basement can add value to a residential property.
Waterproofing also protects against water damage, which decreases the risk of a loss in value. A home that has suffered water damage may become less desirable to potential buyers.

There are also many types of waterproofing available for concrete surfaces. Most options allow you to choose a colour that works well with the rest of the property. Instead of concrete grey, you can choose from a wide selection of colours to suit your tastes.
5. Waterproofing Helps Maintain a Clean Look
Waterproofing exterior surfaces may help boost the curb appeal of a property. It creates a cleaner, smoother appearance compared to bare concrete.
The waterproof layer also helps maintain a clean look for longer. Your newly waterproofed surface should look great with minimal maintenance for many years.
Keeping a waterproof basement floor or garage floor clean is easier compared to dealing with bare concrete. You can easily wash away oil and spills and increase the lifespan of your concrete surfaces.
