Paver installation is one of the most effective ways to enhance the beauty and functionality of your outdoor space. Whether you’re looking to create a stunning patio, walkway, or driveway, mastering the art of proper base preparation is essential to ensuring long-lasting results. In this guide, we’ll walk you through every step of the process, from clearing the area to laying the pavers and sealing them. With the right techniques, you’ll achieve a flawless base that can withstand the test of time—even in Edmonton’s tough climate.
Why Proper Base Prep is Crucial for Paver Installation
The success of your paver installation depends on how well the foundation is prepared. A poorly installed base can lead to uneven surfaces, drainage issues, and the dreaded frost heaving, especially in areas like Edmonton, where winters can be harsh. Without a solid foundation, your pavers are at risk of shifting, cracking, and becoming unstable. But with the right base prep, you can ensure a smooth, durable surface that enhances your landscaping for years to come.
Essential Steps to Prepare the Base for Paver Installation
1. Clearing the Area of All Organics
Before you begin the paver installation, it’s critical to clear the area of all organic materials like grass, roots, and topsoil. Organic matter decomposes over time, which can cause the ground to shift and create instability. For Edmonton landscapes, where frost heaving can be a concern, removing all organic material is a key step.
Once cleared, the area should be graded so that water drains away from any structures. A gentle slope of 1 inch per 8 feet is generally recommended for proper drainage.
2. Preventing Frost Heaving with Geotextile Fabric
Frost heaving, caused by the freezing and thawing of water under the surface, is a common problem in colder climates like Edmonton. To prevent this, we recommend installing a layer of geotextile or commercial-grade landscape fabric. This material acts as a barrier, preventing soil from mixing with the gravel base and allowing water to pass through without causing erosion.
3. Creating the Base: Road Crush and Compacting
Your paver installation’s success relies heavily on the strength of the base. Start by laying a layer of road crush (also known as aggregate or gravel), which should be at least 4 inches thick. For areas like driveways, you may want to increase this thickness to 6-8 inches for additional support.
The key to a strong base is compaction. Compact the base material in 1-inch lifts, using a tamper or plate compactor. The goal is to eliminate any air pockets, creating a dense, stable foundation. This step ensures that the base can support the weight of the pavers and any traffic they’ll endure.
4. Adding Paver Sand or Limestone Fines for Leveling
Once your base is compacted, it’s time to add a layer of paver sand or limestone fines. This layer, usually about 1 inch thick, is essential for leveling the surface before laying the pavers. Spread the material evenly across the base and use a screed board to ensure a perfectly level surface.
In Edmonton, where temperature fluctuations can affect the ground, using high-quality leveling materials will help prevent uneven surfaces and sinking over time.
5. Laying the Pavers
Now comes the fun part—laying the pavers. Begin at a corner or along a straight edge, placing the pavers in your desired pattern. Make sure they are laid close together, with no large gaps, as this can lead to instability.
For Edmonton residents, consider patterns that accommodate freeze-thaw cycles, such as herringbone or basketweave, which provide better interlocking and stability.
- Add a Paver Edge: Adding a paver edge is essential to hold everything in place. This edging provides added stability to prevent shifting and maintain the integrity of your design over time, especially important in areas like Edmonton where ground movement can occur due to temperature fluctuations.
6. Sealing with Polymeric Sand
After laying your pavers, it’s time to seal them in place with Techniseal polymeric sand. This specialized sand, like Techniseal Smart Sand and NextGel, contains advanced additives that harden when wet, locking pavers in place and preventing weed growth. For areas like Edmonton, where weeds can be particularly persistent, using polymeric sand is crucial for long-term maintenance and durability.
Once the Techniseal sand is swept into the joints, lightly mist the surface with water to activate the polymers. Allow the area to dry completely before using the surface. By sealing with high-quality polymeric sand, you’ll help ensure that your paver installation remains stable and weed-free for years to come.
Common Mistakes to Avoid During Paver Installation
Even with the best intentions, mistakes can happen during paver installation. Here are a few common errors to avoid:
- Skipping the Geotextile Fabric: This step is crucial for preventing soil mixing and frost heaving, especially in Edmonton.
- Improper Base Compaction: Failing to compact the base thoroughly can lead to uneven surfaces and shifting pavers.
- Neglecting Drainage: Proper slope and grading are essential for preventing water damage and erosion.
- Not Using Polymeric Sand: Ordinary sand won’t hold the pavers in place as effectively as polymeric sand, leaving them vulnerable to movement and weed growth.
Maintaining Your Paver Installation
Once your pavers are installed, regular maintenance will keep them looking beautiful and functioning properly. Here are some tips for maintaining your paver installation:
- Regular Cleaning: Sweep your pavers regularly to remove dirt and debris. For Edmonton winters, avoid using harsh salts or chemicals that could damage the pavers.
- Weed Control: Although polymeric sand helps prevent weeds, some stubborn weeds may still appear. Pull them as soon as they emerge to keep your pavers looking clean.
- Re-sanding and Sealing: Over time, the polymeric sand may need to be reapplied, especially after heavy rains. Resealing your pavers every few years will also help protect them from stains and weather damage.

How thick should the base be for paver installation in Edmonton?
For most paver installations in Edmonton, a base of 4-6 inches of compacted road crush is ideal. For driveways, consider increasing the thickness to 6-8 inches for added durability.
How do I prevent weeds from growing between my pavers?
Using polymeric sand in the joints between pavers helps prevent weed growth. Regular maintenance and sealing will further reduce the chances of weeds taking root.
Is paver installation a DIY-friendly project?
