Imagine building your dream interlocking patio or pathway with each stone fitting perfectly. It can increase the charm of your landscape, but you would need to follow the proper steps to install interlocking stones. From preparing the base to laying the stones, everything needs your attention. Well, this article presents these easy steps to help you create a captivating space and turn your vision into reality.
Interlocking stone goes in over an excavated, compacted base topped with gravel and bedding sand, held in place by edge restraints and finished with a sealant applied 48 hours after the last paver is set.
A patient homeowner can manage a small paver project, though getting every stone tight and level over a larger surface takes a lot of planning and effort. Our expert interlocking stone walkway team at Synergy Contracting installs interlocking paving stones on patios, walkways and driveways across the GTA, where expertise and a clean result on the first attempt come standard.

7 Steps On How To Install Interlocking Stone
Skipping a stage is how paving stones end up heaving after one winter, which says everything about the importance of the base work. Follow the techniques below in order and give the foundation as much attention as the stones themselves.
Step 1. Examine the Project Space
Walk the space first. Take measurements, run string lines to outline the area, and mark any curves or edges with spray paint so the layout is settled before a single stone arrives. The intended use also shapes the excavation depth, since a driveway carrying vehicle traffic calls for a deeper base than a walkway. Accurate measurements here also tell you how much material to order.
Step 2. Prepare and Level the Base
Clear the area of sod, rocks and loose debris, then dig 6 to 12 inches deep with a shovel. For example, a driveway needs the full 12 inch thickness. Rake the excavation flat and remove any unevenness, then run the plate compactor over the subgrade until compaction is complete. That level bed of compacted soil carries everything that follows.
Step 3. Lay Gravel and Bedding Sand
Spread a layer of gravel as the base material across the excavation, then a layer of concrete sand over top for bedding. These base layers give the surface stability and let water pass through for proper drainage, which helps protect the subgrade against erosion. Use the rake to distribute both evenly.
Step 4. Create Edge Restraints
Install an edge restraint along the full perimeter of the space and secure it with adhesive or spikes. Restraints reinforce the structural integrity of the installation by stopping outward movement once the pavers are under load, which prevents problems such as spreading joints down the road.
Step 5. Install Interlocking Stones
Now the main work begins. Place pavers at one corner and work steadily toward the opposite side, following your desired pattern. Rectangular brick shapes are the most common. Tap each interlocking paver into place with a rubber mallet, making small adjustments as you go and checking that every piece sits level with its neighbours and fits tight against them. A careful installer verifies the joint lines every few rows. Our residential interlocking crews make those corrections early, because a wandering joint line is nearly impossible to fix later.
Step 6. Cut Stones and Fill the Gaps
Edges and gaps almost always call for cut pieces. Measure each one and cut with a circular saw, wearing safety glasses and gloves throughout. Once the layout is complete, run a plate compactor over the surface so the vibration settles the stones into the bedding sand. Then sweep polymeric sand into the joints and pass the compactor over once more, since the joint sand locks the interlocking stone pavers together and blocks weed growth.
Step 7. Finish and Seal the Stones
Sealing is the final stage. Wait 48 hours after installation, then apply a top-quality sealing product to protect against staining and deepen the appearance of the finished interlock. Sealed interlock is durable and low maintenance, and resealing every few years helps maintain that longevity for a long lasting surface.

Frequently Asked Questions
Is interlocking stone better than concrete?
Yes, interlocking stone performs better than poured concrete or asphalt for most driveways and walkways. Individual stones flex with ground movement and freeze-thaw cycles without needing expansion joints, which helps the surface resist cracking, and a damaged paver can be lifted and replaced without disturbing the rest.
What are the basic methods of interlocking?
The three basic methods are mechanical interlocking, push button interlocking and auxiliary contact interlocking. Mechanical interlocking is the standard for landscape work, where compacted bedding sand and tight joints lock each paver against its neighbours. Contractors choose the method based on the project and the material involved.
How do you prepare the ground for interlocking?
Prepare the ground by excavating to depth and compacting the soil into a solid, smooth surface before any bedding sand goes down. Build in a slope of 1/8 to 1/4 inch per foot so water drains away from the finished area. A stable, compacted base keeps stones from shifting later.
