Unilock vs. Belgard Pavers: Which Is Right for Your Fox Valley Home?

Last updated: April 8, 2026

Choosing between Unilock and Belgard pavers is one of the first decisions Fox Valley homeowners face when planning a new patio, walkway, or pool deck. Both are premium brands — widely available, backed by strong warranties, and engineered for cold climates. The real question is which product lines, color palettes, and technologies best match your home’s style and your budget. This guide breaks down both brands side by side so you can make a confident choice. See our paver patio and hardscaping services for the full range of what BLC Yardworks installs across the Fox Valley.

Why the Brand You Choose Matters

Both Unilock and Belgard are manufactured specifically for hardscape professionals and sold exclusively through certified contractors — you won’t find either at a big-box store. Choosing between them shapes your color options, the specific textures available, which product lines are in stock locally, and what warranty coverage you receive. The good news: both are excellent products. BLC Yardworks has been installing pavers since 1999 and is certified by both manufacturers, so this guide reflects real-world experience with both systems in Will, Kendall, and Kane County conditions.

For context on what the full installation process looks like, read about what goes under a paver patio — the base system is the same regardless of which brand tops it.

Unilock Pavers: Product Lines & Technology

Unilock is a North American manufacturer with deep roots in Ontario, Canada — a climate that makes Illinois winters look mild. Their products are engineered for freeze-thaw durability from the ground up. Here’s what distinguishes them:

EnduraColor Technology

Unilock’s EnduraColor process embeds pigment throughout the concrete mix rather than just coating the surface. The result is consistent color that won’t fade, streak, or wear unevenly over time. This matters especially in the Fox Valley, where harsh winters, UV exposure, and de-icing salt can stress lesser pavers.

Popular Unilock Product Lines

• Beacon Hill Smooth — A clean, rectangular paver with a smooth face. Ideal for contemporary homes and modern pool decks. Available in a wide range of neutral tones.
• Umbriano — Unilock’s premium porcelain-look paver. Large-format slabs with a polished aesthetic. Popular for upscale patios and outdoor kitchens where a refined look is the goal.
• Brusselstone — A tumbled, old-world cobblestone style. Works beautifully on traditional and craftsman-style homes. Highly popular in Plainfield and Oswego neighborhoods with brick architecture.
• Thornbury — A sawn-cut product with a natural split-stone appearance. Offers the look of irregular flagstone with the consistency and durability of manufactured pavers.

Unilock also offers a broad selection of retaining wall systems (Rivercrest, Pisa2) and wall caps that coordinate with their paver lines — useful when your project includes fire pits and seat walls that need to match the patio surface.

Belgard Pavers: Product Lines & Technology

Belgard is a brand under Oldcastle Infrastructure and has manufacturing facilities throughout North America. They are particularly known for large-format pavers and a wide range of natural-looking textures. Their flagship technology is different from Unilock’s in an important way:

Omniffuse Color Distribution

Like Unilock’s EnduraColor, Belgard’s Omniffuse process distributes color throughout the paver body — not just the surface layer. This ensures that chips, scratches, or wear don’t expose a different-colored core beneath. The technology delivers consistent color performance throughout the paver’s lifespan.

Popular Belgard Product Lines

• Cambridge Cobble — One of Belgard’s most versatile and popular products. A multi-piece system with cobblestone character. Pairs well with traditional and transitional architectural styles.
• Mega Arbel — A large-format paver with a natural, textured surface reminiscent of irregular stone. Lays quickly and provides a high-end look on expansive patio areas.
• Brussels Block — A classic European cobblestone-style paver. One of Belgard’s longest-running products with a proven track record in Illinois climates.
• Weston Stone — A large rectangular paver with a clean profile. Popular for contemporary landscapes and linear pool deck designs.

Belgard also offers a matching wall block system (Celtik Wall, Weston Wall) that coordinates with their paver lines — important when designing a cohesive outdoor space. Learn more about how pavers and wall systems come together on our project gallery.

Unilock vs. Belgard: Side-by-Side Comparison

Here is a direct comparison across the categories that matter most to Fox Valley homeowners:

Performance in Fox Valley’s Freeze-Thaw Climate

Will, Kendall, and Kane County experience 20–50 freeze-thaw cycles every winter — water expands as it freezes and contracts as it thaws, putting stress on any hardscape material. Both Unilock and Belgard pavers are manufactured to withstand this cycle, but the paver itself is only part of the equation.

The real protection against frost heave comes from the base system beneath the pavers:

1. Excavation depth — Minimum 8–10 inches in clay-heavy Fox Valley soils to get below the active freeze zone
2. Compacted aggregate base — Properly graded crushed stone (CA-6 or equivalent) compacted in lifts allows water to drain away before it can freeze and expand
3. Bedding sand layer — 1-inch screeded sand layer provides the final leveling surface
4. Joint sand — Polymeric sand locking the joints prevents water intrusion and weed growth

Fox Valley clay soils are expansive — they absorb water and swell. Without proper drainage built into the base, even the best pavers will shift, settle, and crack within a few seasons. This is why drainage solutions are frequently part of a patio project, not an afterthought.

Both Unilock and Belgard pavers have been tested to ASTM standards for freeze-thaw resistance, water absorption, and compressive strength. Either brand, installed correctly, will perform for decades in Illinois.

How to Choose: Style, Budget, and Project Type

Here’s a practical framework for deciding between Unilock and Belgard for your project:

Choose Unilock if:

• Your home has a traditional brick or European architectural style (Brusselstone and Thornbury complement these beautifully)
• You want a premium porcelain-look large-format paver (Umbriano is the top choice in this category)
• You’re building a cohesive outdoor room with seat walls, steps, and a fire pit using a coordinated product system
• You value Unilock’s regional presence and the breadth of their authorized contractor network — find a contractor at Unilock’s contractor locator

Choose Belgard if:

• You want a large-format natural stone appearance (Mega Arbel is excellent for expansive patios)
• Your project calls for a more contemporary aesthetic with clean lines (Weston Stone)
• You’re drawn to the classic cobblestone look with a proven Fox Valley track record (Cambridge Cobble)
• You want to verify contractor credentials via Belgard’s contractor finder

Consider Both if:

Your project has multiple components — for example, a patio with a retaining wall or steps — and you’re choosing based on which brand’s coordinating wall system matches your vision. Bring photos of your home’s exterior to your consultation. The single most useful thing you can do is bring reference images of styles you like.

Why Contractor Certification Matters

Both Unilock and Belgard sell their products exclusively through certified contractors and require installation by those contractors to activate their full warranty coverage. Certification isn’t just a marketing designation — it means the contractor has been trained on proper base preparation, installation techniques, and the specific requirements of each product line.

BLC Yardworks has been Unilock and Belgard certified since the early 2000s. We’ve installed both systems on hundreds of Fox Valley properties across Plainfield, Oswego, Yorkville, Naperville, Aurora, Geneva, St. Charles, Batavia, and Montgomery. That depth of local experience matters because we know the soil conditions, drainage patterns, and permit requirements specific to each municipality.

Regardless of which brand you choose, your warranty is only as good as the installation behind it. A properly installed base — adequate depth, proper compaction, good drainage — is what separates a patio that lasts 30 years from one that needs repairs in five. For more on the installation process, read about BLC’s project process or see how long installation typically takes in our guide to how long patio installation takes.

Once your patio is installed, protect your investment with our paver maintenance guide — sealing, joint sand refresh, and annual inspection keep both Unilock and Belgard pavers looking new for decades.

Frequently Asked Questions

What is the difference between Unilock and Belgard pavers?

Unilock and Belgard are both premium paver manufacturers offering lifetime-limited warranties and freeze-thaw-resistant products. Unilock is known for its European-inspired designs and EnduraColor pigmentation technology. Belgard specializes in large-format natural stone looks and its Omniffuse color distribution system. Both perform excellently in Fox Valley conditions when installed over a properly prepared base.

Are Unilock or Belgard pavers better for the Fox Valley Illinois climate?

Either brand performs well in the Fox Valley’s harsh winters when installed correctly. Illinois experiences 20–50 freeze-thaw cycles per winter, and both Unilock and Belgard products are ASTM-tested for freeze-thaw resistance. The greater variable is base preparation — proper excavation depth, compacted aggregate drainage, and joint sand quality matter more than which brand is on top. BLC Yardworks is certified by both and installs both systems to each manufacturer’s specifications.

Do Unilock and Belgard pavers come with a warranty?

Yes. Unilock offers a limited lifetime warranty on manufacturing defects and color fading, requiring installation by an authorized contractor. Belgard’s Belgard Authorized Contractor (BAC) program offers a similar lifetime limited product warranty. Choosing a certified installer like BLC Yardworks is required to activate full warranty coverage for either brand.

How much do Unilock vs. Belgard pavers cost installed?

Material costs are comparable between the two brands: standard product lines run roughly $3–$8 per square foot in materials, while premium large-format lines (Umbriano, Mega Arbel) run $8–$15+ per square foot. Fully installed, Fox Valley patio projects typically cost $16–$25 per square foot for standard work and $25–$40 or more for premium products or complex designs. See our Fox Valley hardscaping cost guide for a full breakdown.

Can I compare Unilock and Belgard samples before deciding?

Absolutely. When you schedule a consultation with BLC Yardworks, we bring physical samples from both brands so you can see and feel the textures, hold the colors next to your home’s brick or siding, and compare options side by side. We strongly recommend viewing samples in the actual outdoor light conditions of your space before finalizing a choice.
