They’re manufactured to mimic brick or natural stone, giving you a high-quality look at a fraction of the cost. Plus, most homeowners can install them on their own. Whether you’re looking to enhance your home’s curb appeal or create a functional pathway to your front entrance, a concrete paver walkway is an excellent DIY project that delivers professional-looking results without requiring specialized skills or expensive equipment.

In the video above, This Old House host Kevin O’Connor and landscape contractor Roger Cook demonstrate how to create a new walkway using concrete pavers. This guide provides comprehensive step-by-step instructions to help you build your own beautiful and durable concrete paver walkway.

Preparing for Concrete Paver Installation

Good prep work is key for a successful installation. This phase involves planning, gathering materials, and preparing the site properly. Taking time upfront to plan and prepare will ensure that your finished walkway is both beautiful and durable, lasting for many years with minimal maintenance.

Planning Your Walkway

Before breaking ground, consider the following important factors:

Color scheme and paver style: Select pavers that complement your home’s exterior colors and architectural style. Concrete pavers come in various colors and finishes, allowing you to match your home’s aesthetic perfectly.

Desired pattern: Choose a pattern such as running bond, herringbone, or basketweave. The running bond pattern, where all bricks run in the same direction, is one of the simplest and most popular choices for walkways, requiring minimal cuts.

Drainage requirements: Create good drainage to prevent water buildup. Proper drainage is essential for preventing water damage and ensuring the longevity of your walkway, particularly in areas with heavy rainfall or freeze-thaw cycles.

Walkway dimensions and layout: Determine the length, width, and path of your walkway. Standard walkways are typically 3 to 4 feet wide, allowing two people to walk side by side comfortably.

Site Preparation

Good site preparation will help you build a stable and long-lasting walkway. Take these steps before beginning installation:

• Mark the walkway area using stakes and string to define the exact path and dimensions
• Excavate the marked area to a depth of 8–10 inches, removing all loam and clay to the subgrade
• Add a layer of crushed limestone base (crusher run) approximately 4 inches thick and rake it to be level
• Compact the crushed stone using a plate compactor to create a solid foundation that prevents settling

The foundation is critical to your walkway’s success. A poorly prepared base can lead to uneven surfaces, settling, and premature failure of your paver installation. By taking time to properly compact each layer, you’re investing in the longevity of your project.

Installing the Concrete Pavers

With the site prepared, you’re ready to begin laying the pavers. This requires attention to detail to make a flat and secure walkway. The installation process involves several key steps that must be executed carefully for optimal results.

Laying the Sand Base

To start, spread a 1-inch layer of concrete sand over the compacted stone base. Use a screed board to level the sand, creating a smooth surface for the pavers. The sand layer provides a cushion for the pavers and allows for minor height adjustments. Make sure the sand is evenly distributed across the entire work area before proceeding to the next step.

Setting the Pavers

Begin laying pavers at one end of the walkway, following your chosen pattern. Take advantage of the paver “nubs”—small protrusions on the sides that keep consistent spacing between each paver. These nubs eliminate the guesswork and ensure uniform gaps for a professional appearance.

Tap each paver gently into place with a rubber mallet, working methodically from one end to the other. This consistent approach helps maintain level surfaces and proper alignment. As you work, periodically check your progress with a level to ensure the walkway remains flat.

Cut pavers as needed to fit at the edges using a circular saw with a masonry blade. Running bond patterns typically require only a few cuts at the end and front of the walkway, making this one of the most efficient patterns for DIY installation. Wear safety glasses and a dust mask when cutting pavers to protect yourself from concrete dust.

Finishing Your Concrete Paver Walkway

The final steps are crucial for creating a durable walkway that will last for years. These finishing touches complete the installation and lock everything securely in place.

Installing Edge Restraints

Plastic edging goes between the edge of the paver and the yard to hold the bricks right in place. Drive a spike down through the edging into the ground. This edging is essential for preventing the pavers from shifting outward over time and for containing the sand between the joints.

Applying Polymeric Sand

The secret to a good walk is to sweep the joints in with polymeric sand. This special sand contains additives that, when activated with moisture, harden and lock the pavers together. Follow these steps:

• Sweep polymeric sand generously across the entire walkway surface
• Use the compactor to vibrate the pavers and move the polymeric sand down into the joints
• Sweep off excess sand from the paver surface
• Mist the bricks with water so that the polymeric sand gets washed down and activated
• Allow the sand to cure according to manufacturer’s instructions before walking on the surface

Polymeric sand is significantly stronger than regular sand and prevents weeds from growing between pavers while maintaining flexibility for seasonal expansion and contraction. This is a critical step that many DIYers overlook, so take your time to do it properly.

Project Timeline and Considerations

Depending on the size of your walkway, this project can typically be completed within a single day, though larger installations may require additional time. The timeline breaks down approximately as follows:

• Planning and material gathering: 1-2 hours
• Site excavation and base preparation: 2-4 hours depending on walkway size
• Paver installation: 3-6 hours
• Finishing and polymeric sand application: 1-2 hours

Tools and Materials You’ll Need

Concrete Paver Advantages Over Traditional Concrete

When compared to traditional poured concrete, concrete pavers offer several distinct advantages. They provide superior aesthetics with a variety of colors and textures that replicate natural stone or brick. They’re easier to repair—if one paver becomes damaged, you simply replace that individual paver rather than resurfacing the entire walkway. Pavers also offer better drainage, as water passes through the joints rather than pooling on the surface.

Additionally, concrete pavers are less prone to cracking from freeze-thaw cycles because they can shift slightly as the ground expands and contracts. Installation is also more forgiving, as minor height differences between pavers are less noticeable than with poured concrete.

Maintenance Tips for Your Paver Walkway

To keep your concrete paver walkway looking beautiful for years to come, follow these maintenance guidelines:

• Sweep regularly to remove dirt and debris
• Wash with a garden hose to prevent moss and algae buildup
• Reapply polymeric sand every 3-5 years or as needed
• Remove weeds promptly if they appear between pavers
• Avoid using harsh chemical cleaners that may damage the pavers
• Fill any significant depressions with additional sand if settling occurs

Frequently Asked Questions

Q: How long does it take to build a concrete paver walkway?

A: Depending on the size of your walkway, most projects can be completed within a single day. Larger installations or more complex patterns may require additional time. The complexity of cuts needed and the size of your work area are the primary factors affecting timeline.

Q: Do I need special tools to cut concrete pavers?

A: Yes, you’ll need a circular saw with a masonry blade to cut concrete pavers. A wet saw is even better for cleaner cuts with less dust. Make sure to wear safety glasses and a dust mask when cutting to protect yourself from concrete dust particles.

Q: What is polymeric sand and why is it important?

A: Polymeric sand is specially formulated sand that contains additives that harden when exposed to moisture. It prevents weeds from growing between pavers, keeps the pavers locked in place, and prevents sand from washing away during rain. It’s essential for a long-lasting, low-maintenance walkway.

Q: How deep should I excavate for a paver walkway?

A: Excavate to a depth of 8-10 inches total. This typically includes approximately 4 inches of compacted crushed limestone base, 1 inch of sand, and the height of your pavers (usually 2-3 inches for concrete pavers), leaving your finished walkway flush with or slightly above the surrounding grade.

Q: What paver pattern is best for a beginner?

A: The running bond pattern is ideal for beginners. In this pattern, all pavers run in the same direction, requiring minimal cuts—typically just at the ends of the walkway. This makes installation faster and easier while still looking professional and attractive.

Q: Can I install a concrete paver walkway myself?

A: Yes, most homeowners can successfully install a concrete paver walkway themselves. The project requires basic tools and intermediate DIY skills. The key is proper site preparation, attention to detail during installation, and patience with the finishing steps, particularly with the polymeric sand application.

Q: How do I ensure proper drainage for my paver walkway?

A: Ensure proper drainage by establishing a slight slope (1/4 inch per foot) during the sand base preparation. This allows water to run off rather than pooling. The gaps between pavers with polymeric sand also provide excellent drainage, allowing water to permeate through to the base below.

Q: What should I do if pavers settle after installation?

A: Minor settling is normal. If significant settling occurs in one area, you can carefully remove those pavers, add additional sand to the base, recompact, and reinstall the pavers. Proper initial base preparation usually prevents major settling issues.
