Interlock Driveway, Patio & Walkway Repair
Horvath Landscapes repairs interlock driveways, patios, and walkways across Aurora, Newmarket, Richmond Hill, North York, and King City.
Interlock stone surfaces are designed to last for decades, but over time natural soil movement, freeze–thaw cycles, and everyday use can cause sections of a driveway, walkway, or patio to settle or shift.
At Horvath Landscapes, we specialize in repairing and restoring existing interlock installations so homeowners can extend the life of their driveway or patio without the cost of a full replacement.
Many interlock repairs involve lifting the existing pavers, rebuilding the base with properly compacted granular material, and reinstalling the stones so the surface is level and structurally sound again.
In many cases, the original pavers can be reused, allowing homeowners to restore the appearance and functionality of their landscape while preserving the character of the original installation.
Common Interlock Problems We Repair
Interlock repairs are often needed when homeowners notice:
-
Sunken or uneven driveways
-
Trip hazards on walkways
-
Water pooling near the garage or front entrance
-
Broken or cracked pavers
-
Failing borders or retaining edges
-
Weeds growing between pavers
-
Settling near foundations or retaining walls
These issues typically occur because the base beneath the pavers has shifted over time. When properly repaired, the surface can often perform well for many more years.
Our Interlock Repair Process
When repairing interlock surfaces, Horvath Landscapes focuses on correcting the underlying issue rather than simply adjusting the surface.
Typical repairs include:
-
Carefully removing the existing pavers
-
Rebuilding or correcting the base material
-
Adding proper compaction to stabilize the surface
-
Reinstalling the original stones in their pattern
-
Replacing damaged pavers where necessary
-
Installing polymeric sand to stabilize the joints
This process restores the structural integrity of the installation while maintaining the appearance of the original design.
Interlock Repair Projects
Below are several examples of interlock driveway, patio, and walkway repairs completed by Horvath Landscapes over the years. These examples demonstrate how repairs can restore older installations and extend their lifespan while preserving the original materials.
Driveway & Front Entrance Repair with Flagstone Porch – North York
This driveway and front entrance repair in North York involved restoring a settled interlock driveway while upgrading the front steps and porch with natural stone. Years after the home had been built, normal settlement in the backfilled areas caused sections of the driveway and front entrance to sink. Horvath Landscapes rebuilt the base, relaid the interlock driveway, and enhanced the front entrance with durable Indian flagstone and natural stone steps.
Project Story
Many homes experience settlement in the years following construction, especially where large areas of soil were backfilled around foundations, driveways, and front entrances. Over time, natural soil movement combined with vehicle traffic and freeze–thaw cycles can cause interlock driveways and walkways to sink slightly.
In this North York project, the homeowner wanted to address the settlement while also improving the appearance of the front entrance. The existing interlock driveway was carefully lifted so the base could be corrected and properly compacted before the pavers were reinstalled.
At the same time, the front entrance was upgraded using Indian flagstone for the porch surface, creating a more natural and welcoming entry. The original steps were replaced with large natural stone (India stone) slabs, providing wider, more comfortable treads and a stronger visual presence at the front of the home.
The retaining walls around the steps were repaired, and several damaged driveway pavers were replaced with matching materials where possible. To further enhance the entrance, decorative granite boulders that were not serving a structural purpose were replaced with properly placed armor stone, giving the steps a cleaner and more balanced appearance.
Because this driveway slopes downward toward the garage—a common design in parts of North York—the drainage system was also inspected and cleaned to ensure proper water flow. Once the base corrections were complete, the interlock driveway was relaid, leveled, and finished with polymeric sand to stabilize the surface.
The final cleaning of the driveway and entrance happened just before the photos were taken, leaving the stone surfaces looking rich and vibrant even under overcast conditions.
Interlock Driveway Repair & Refresh – Aurora
This interlock driveway repair in Aurora focused on restoring an older driveway that had begun to show its age. Over time, several pavers had cracked and the surface had become uneven. Horvath Landscapes repaired the driveway by re-leveling the base, replacing damaged pavers, and adding new borders to refresh the overall appearance while keeping most of the original materials.
Project Story
After more than two decades of regular use, the homeowner’s interlock driveway was beginning to look tired. A number of pavers had cracked or broken, and some minor settling had occurred in sections of the driveway. While the overall structure of the driveway was still sound, the surface needed attention to restore its appearance and maintain a level surface.
The homeowner’s goal was not to replace the entire driveway but to improve its look and extend its lifespan using the existing materials wherever possible.
The Horvath Landscapes team carefully lifted the affected areas of the driveway and corrected the base where minor settlement had occurred. Broken pavers were removed and replaced with complementary materials. To enhance the appearance of the driveway, a new border detail was introduced using Unilock wet-cast pavers, which naturally have a subtle sheen due to their manufacturing process. This small upgrade helped refresh the overall look of the driveway and gave it a cleaner, more finished appearance.
Once the driveway was relaid and leveled, polymeric sand was installed between the joints to help stabilize the pavers and reduce weed growth. The result was a driveway that looked significantly renewed while still maintaining its original character.
Repairs like this can often extend the life of an interlock driveway for many additional years. For homeowners who want to further protect their pavers from moisture and freeze–thaw cycles, penetrating sealers such as siloxane-based sealerscan be applied. These products soak into the pores of the concrete and help reduce water absorption without creating a glossy surface.
More than ten years after this repair was completed, the driveway continues to perform well and still looks great.
Circular Interlock Driveway & Front Entrance Repair – Aurora
This interlock driveway and front entrance repair in Aurora involved restoring a complex paver pattern made up of circles and fan designs. The driveway had settled after many years of use, and the retaining walls supporting the front steps also required repair. Horvath Landscapes carefully lifted and rebuilt sections of the driveway while preserving the original circular pattern that defined the design.
Project Story
Many interlock driveways installed in the late 1990s and early 2000s used decorative circular and fan patterns, which were very popular at the time. While these patterns create beautiful driveways, they can also make repairs more complicated because every stone must be returned to its original position to maintain the geometry of the design.
In this Aurora project, years of vehicle traffic and natural freeze–thaw cycles had caused portions of the driveway and front entrance to settle slightly. Because the installation had originally been completed when the house was new, some settlement in the backfilled areas near the foundation and driveway edges was expected over time.
The Horvath Landscapes team carefully removed the pavers while keeping the circular and fan patterns organized so they could be reinstalled exactly as they were originally laid. Maintaining the pattern was critical to avoid unnecessary cutting and to preserve the visual symmetry of the driveway.
During the repair, the retaining walls supporting the front steps were also rebuilt. Old adhesive was ground off the wall caps so new structural adhesive could be applied for a stronger bond. The base beneath the pavers was improved with additional granular material before the driveway stones were relaid and leveled.
Because the original pavers were no longer available, a few damaged stones were replaced with complementary materials, and subtle border accents were added to the steps to maintain a clean and finished appearance.
While the final completed photos were unfortunately not captured at the time, the project photos show the repair process and demonstrate Horvath Landscapes’ experience working with intricate interlock driveway patterns that require careful planning and precise reinstallation.
Front Walkway & Steps Repair with Porch Waterproofing – Aurora
This front walkway and steps repair in Aurora involved correcting severe settlement caused by an inadequate base beneath the original installation. Horvath Landscapes rebuilt the base structure and improved waterproofing around the porch to restore the walkway and steps to a safe and durable condition.
Project Story
The homeowners contacted Horvath Landscapes after noticing significant settling along their front walkway and steps only a few years after the original installation. In several areas the walkway had dropped dramatically—up to eight inches in one section—creating uneven surfaces and potential drainage concerns near the porch.
Although the original stonework had been carefully cut and initially looked very attractive, the underlying base materials had not been properly prepared. When the repair began, it became clear that much of the base beneath the pavers consisted of soil rather than properly compacted granular material. Without a stable base, the walkway gradually settled as the soil shifted over time.
To correct the problem, the Horvath Landscapes team carefully excavated the existing materials and removed the unsuitable soil that had been used beneath the installation. The area was then rebuilt using proper granular base materials, placed and compacted in layers to create a stable foundation.
During the repair process, additional attention was given to protecting the home’s structure. The concrete porch surface and surrounding areas were waterproofed to help prevent water infiltration and future deterioration near the entrance.
Once the base corrections and waterproofing work were completed, the walkway and steps were rebuilt and leveled to restore proper elevation and drainage. The result was a front entrance that was both visually appealing and structurally sound for long-term use.

Vintage Interlock Driveway Restoration & Drainage Upgrade – North York
This driveway repair in North York involved restoring one of the older interlock driveways Horvath Landscapes has worked on. The driveway had originally been installed around the time the home was built more than 40 years earlier. Our goal was to rebuild the base, improve drainage near the garage, and refresh the appearance of the driveway while preserving the original pavers wherever possible.
Project Story
When the homeowner contacted Horvath Landscapes, their interlock driveway had already served the home for roughly four decades. Despite its age, the original pavers were still structurally sound. Many early interlocking pavers were designed with shapes that physically locked together, creating a very stable surface when properly installed.
Over time, however, the edges of the driveway had begun to deteriorate. The original pressure-treated wood borders had rotted and were no longer holding the driveway securely. The driveway also sloped slightly toward the house, and during heavy rain events water would occasionally move toward the garage.
To correct these issues, the Horvath Landscapes team carefully lifted the entire driveway so the base could be adjusted and re-leveled. New clay pavers were installed along the edges to create durable borders that would hold the driveway in place for the long term.
Drainage was also improved by installing an Eco-Drain system near the garage entrance to capture and redirect water during heavy rainfall. Once the base was corrected, the original interlocking pavers were relaid and stabilized with polymeric sand.
One interesting detail about this driveway was the color variation in the original pavers. Early concrete pavers were often produced in different dye batches, which sometimes resulted in visible color variation across the surface. While subtle, this variation tells part of the story of the driveway’s age and history.
The completed repair restored the driveway’s function and appearance while preserving materials that had already performed well for decades. More than ten years after the repair, the homeowners contacted Horvath Landscapes again to complete additional work on their property, a relationship we greatly value.
Repair vs Replacement
One of the most common questions homeowners ask is whether they should repair their interlock or replace it entirely.
Repair is often the best option when:
-
The majority of the pavers are still in good condition
-
The problem is localized settlement or base failure
-
The homeowner wants to preserve the existing materials
-
The design and layout still work well for the space
Replacement may be recommended when the surface has extensive damage or when the homeowner wants to change the layout or materials.
Because every property is different, we typically assess the condition of the installation before recommending the most practical solution.
Protecting Your Interlock After Repair
After an interlock repair is completed, there are several ways to help maintain the surface.
Polymeric sand is commonly used between the pavers to help reduce weed growth and keep the stones tightly locked together.
Some homeowners also choose to apply a penetrating sealer. Modern sealers such as siloxane-based sealers help reduce water absorption and protect the concrete from freeze–thaw damage without creating a glossy surface.
