Can you install paver blocks on existing concrete?

In this article, we will explore this question and provide you with all the information you need to know.

The Advantages of Installing Paver Blocks

Before discussing whether you can install paver blocks on existing concrete, let’s take a look at the advantages of choosing paver blocks for your outdoor flooring needs.

1. Versatility: Paver blocks come in a wide range of styles, shapes, colors, and sizes, allowing you to create a customized look that complements your existing landscape and personal taste.
2. Easy Maintenance: Paver blocks are relatively low-maintenance. If a paver block gets damaged, it can be easily replaced without disturbing the surrounding area.
3. Durability: Paver blocks are designed to withstand heavy loads and harsh weather conditions, making them an ideal choice for driveways and high-traffic areas.
4. Enhanced Aesthetics: Paver blocks offer a visually appealing alternative to plain concrete. Their textured surface and varied colors can dramatically improve the overall appearance of your outdoor space.

The answer is yes, you can install paver blocks on existing concrete, but there are several factors to consider before undertaking this project.

1. Condition of the Concrete: Before installing paver blocks on top of existing concrete, you must assess the condition of the concrete. If there are significant cracks, sinking, or other structural issues, it is not advisable to proceed with the installation. These problems should be addressed and repaired first to ensure a stable foundation for the paver blocks.
2. Evenness of the Surface: Paver blocks require a level surface to ensure proper installation and prevent shifting or sinking over time. If the existing concrete surface is uneven, you may need to consider leveling techniques, such as adding a layer of mortar, before laying the paver blocks.
3. Height Considerations: Installing paver blocks on top of existing concrete will raise the height of the surface. It is essential to take this into account, particularly when adjacent areas or structures are involved. Ensure that the increased height will not cause any issues, such as drainage problems or interference with doorways or gates.

Steps to Install Paver Blocks on Existing Concrete

If you have assessed the condition of your existing concrete and determined it is suitable for installing paver blocks, here are the general steps to follow:

1. Clean the Surface: Thoroughly clean the existing concrete surface, removing any debris, dirt, or loose material. This will ensure proper adhesion between the concrete and paver blocks.
2. Plan and Layout: Proper planning and layout are crucial for a successful installation. Determine the pattern and design you want to achieve. Consider using string lines and stakes to guide the placement of the paver blocks.
3. Prepare the Base: Depending on the condition of the existing concrete, you may need to apply a layer of mortar or a leveling compound to create a smooth and even surface. Follow the manufacturer’s instructions for the specific product you are using.
4. Lay the Paver Blocks: Start laying the paver blocks in the desired pattern, starting at one end and working your way to the opposite end. Ensure the blocks are placed firmly and level on the prepared surface.
5. Cut the Blocks: In some cases, you may need to cut paver blocks to fit around edges, corners, or obstacles. Use a masonry saw or diamond blade to make accurate cuts.
6. Fill the Joints: Once all the paver blocks are in place, fill the joints between them with fine sand or polymeric sand, sweeping it into the gaps and compacting as necessary. This will help stabilize the blocks and prevent weed growth.
7. Seal the Surface: Consider applying a sealant to the paver blocks to enhance their longevity, prevent staining, and protect them from the elements. Follow the manufacturer’s instructions for the appropriate sealant to use.

Installing paver blocks on existing concrete is indeed possible under certain conditions. Assessing the condition of the concrete, ensuring an even surface, and taking height considerations into account are all crucial steps. With proper planning and execution, you can transform your existing concrete into a beautiful and functional outdoor space using paver blocks. Always follow the manufacturer’s instructions and seek professional guidance if needed to ensure a successful installation.
