Interlock Stone vs. Natural Stone: Which Walkway is Right for You?

A well-designed walkway is more than just a path—it’s a welcome mat to your home, a guiding line through your garden, and a lasting impression for guests. When it comes to building that perfect walkway in Ontario, two popular contenders often come up: interlock stone and natural stone. Both offer beauty and durability, but they have unique benefits, maintenance needs, and aesthetics. So which one is right for you?

Let’s walk through the pros and cons of each.

Interlock Stone: The Customizable Classic

Interlocking stone (or concrete pavers) has long been a go-to for homeowners seeking versatility and value. These manufactured stones come in a range of colors, patterns, and shapes—allowing for endless creativity and control.

Pros:

Design Flexibility: You can create anything from a traditional herringbone layout to modern linear lines or circular medallions.

Easy Repairs: If a paver cracks or shifts, it can be lifted and replaced without disturbing the rest.

Cost-Effective: Generally more affordable than natural stone, especially for larger walkways.

Durability: Engineered for freeze-thaw cycles, interlock pavers are a solid choice for Ontario’s unpredictable seasons.

Cons:

Looks Manufactured: While many interlock options mimic natural textures, the uniformity may lack the organic charm of real stone.

Weed Growth: Gaps between pavers can invite weeds if not sealed or maintained properly.

Polymeric Sand Isn't Forever: While polymeric sand helps lock pavers in place and prevent weed growth, it typically needs to be reapplied every 3 to 7 years. Over time, it can erode, especially in high-traffic or heavily watered areas. So while it’s not a deal-breaker, it’s not a “set it and forget it” solution either.

Natural Stone: Rugged Beauty with Timeless Appeal

Natural stone, like flagstone or limestone, offers one-of-a-kind beauty. Each stone is unique in shape, texture, and tone—making your walkway a piece of art forged by nature itself.

Pros:

Longevity: Stone ages gracefully and often outlasts concrete with minimal wear.

Eco-Friendly: It’s a low-impact, sustainable material—especially if sourced locally.

Cons:

Higher Cost: Both materials and labor are typically more expensive due to cutting, fitting, and weight.

Installation Skill Required: Laying natural stone is like solving a giant puzzle—it requires experience and time.

Uneven Surface: Some stones may not sit flush, which can be tricky for accessibility or furniture placement.

So, Which Should You Choose?

If you want a budget-friendly, modern, and flexible walkway with manageable upkeep, interlock stone is a great pick. Just keep in mind that maintenance includes occasional leveling and refreshing the polymeric sand.

If your heart is drawn to the raw, organic beauty of nature and you’re investing in long-term aesthetics, natural stone delivers a premium look with less frequent maintenance—but a bigger upfront investment.

A Thoughtful Blend?

For the best of both worlds, consider combining the two—interlock for structure and ease, and natural stone insets or borders for organic flair. Many Ontario landscape designers are embracing these hybrid designs to offer both beauty and function.

No matter what you choose, a professionally installed walkway will elevate your landscape, invite people in, and add lasting value to your home.
