5 Ways to Retain a Paver Edge
Types of Edge Restraint Systems
Choosing the right edge restraint system depends on factors like project needs, budget, and the expected traffic load. Concrete, plastic, and metal options each bring their own advantages. Here’s a closer look at what each type offers and how they are installed.
Concrete Edge Restraints
Concrete edge restraints are the go-to choice for heavy-duty paver installations. They are often made using poured-in-place concrete curbs or precast units, creating a sturdy and permanent barrier around the paver area. Thanks to their strength, they’re a solid pick for municipal and commercial projects that need to handle heavy traffic.
However, installing concrete restraints requires careful preparation, including precise excavation, forming, and curing. This adds time to the project, but the payoff is exceptional durability. Weather is also a big consideration – pouring concrete during freezing temperatures or heavy rain isn’t feasible. While the upfront costs for materials and labor may be higher, concrete restraints deliver reliable, long-term performance for permanent applications.
Plastic and PVC Edge Restraints
If you’re looking for something lighter and more budget-friendly, plastic and PVC restraints are worth considering. These systems often come in interlocking sections or continuous strips, which can be easily trimmed to fit curved or straight designs. Installation is straightforward, typically involving basic excavation and securing the restraints with spikes through pre-drilled holes. This simplicity makes them a popular choice for DIY projects or when time is tight.
Plastic and PVC restraints are generally less expensive than concrete systems, both in terms of materials and labor. They also have the flexibility to adapt to ground movement and settling, which is especially useful in regions with expansive soils or frequent freeze-thaw cycles.
Metal Edge Restraints
Metal edge restraints, made from materials like aluminum or galvanized steel, strike a balance between durability and versatility. Aluminum is lightweight and resists corrosion, making it easy to shape, while galvanized steel offers excellent strength and holding power.
Installing metal restraints involves staking and backfilling, but it skips the curing time needed for concrete systems. These restraints are commonly used in residential and light commercial projects, such as driveways, pool decks, and walkways, where both durability and ease of installation are priorities. When installed correctly, metal restraints provide long-lasting performance with minimal upkeep, making them a practical and reliable choice.

Installation Best Practices for Edge Restraints
Getting the installation right is key to keeping pavers stable over time. One of the most important factors to consider is the type of soil, as this affects how edge restraints are anchored.
Working with Different Soil Types
In sandy soils, edge restraints need to be anchored deeper to ensure they stay securely in place [1].
For areas where freeze-thaw cycles cause soil to heave, it’s important to extend the aggregate base beyond the restraint spikes. The extension should match the depth of the base itself – so, if you’re using a 6-inch base, extend it 6 inches past the spikes [1].

Long-Term Performance and Maintenance
Edge restraints are built to handle the challenges of weather, soil shifts, and the weight of pavers. However, their durability depends on addressing potential problems early and taking preventive measures.
Common Problems with Edge Restraints
- Shifting and Movement: Restraints can move out of place if they aren’t anchored deeply enough or if soil conditions change. This is particularly common in areas with expansive clay or loose, sandy bases.
- Spike Failure: Repeated freeze-thaw cycles can loosen or break spikes. Plastic restraints are especially vulnerable in cold weather, as they can become brittle.
- Cracking and Deterioration: Each material comes with its own set of challenges. Concrete restraints may crack, allowing water to seep in, while plastic restraints can degrade under prolonged UV exposure. Metal restraints, on the other hand, may corrode if their protective coatings wear off.
- Base Erosion: Poor drainage can lead to erosion beneath restraints, causing uneven settling and weakening the stability of the paver system.
Maintenance Tips for Longevity
- Regular Inspections: Check edge restraints periodically for signs of misalignment, shifting, or damage. Spotting issues early makes repairs easier and more effective.
- Prompt Repairs: Address problems as soon as they arise. Tighten or replace loose spikes and repair small cracks before they worsen.
- Proper Drainage: Ensure that drainage paths remain clear to prevent water from pooling, which could destabilize the base.
- Seasonal Checks: After freeze-thaw cycles, inspect the restraints for any changes or damage that might require adjustments or additional anchoring.
- Professional Evaluations: For larger projects or areas with challenging soil conditions, consider hiring a professional to periodically assess the restraint system.
By staying proactive with maintenance, you can keep your paver system aligned and avoid costly repairs down the road.
Cost-Effectiveness Over Time
Investing in high-quality edge restraints and maintaining them regularly is a smart way to protect your paver system over the long term. While premium materials may cost more upfront, their longer lifespan and reduced need for major repairs can save money in the long run. This approach not only maintains the structural integrity and appearance of your paved areas but also helps retain the overall value of your property.
