Interlock driveways, patios, and walkways are a long-lasting and visually striking way to enhance your property. At A1 Top Hat, we design and install custom interlock surfaces built to withstand Ottawa’s freeze-thaw climate while improving curb appeal and property value.
From new installations to repairs and restoration, our team delivers durable workmanship using proven materials and professional installation methods.
We use high-quality interlock stones, polymeric joint sand, and rigid edge restraints to ensure long-term performance.
Polymeric sand helps lock pavers together, prevents weed growth, and reduces joint erosion, while proper edge restraints keep stones from shifting over time. These details make a major difference in the lifespan of your interlock surface.
We work closely with you to create stunning, functional interlock designs that complement your property and lifestyle. From stone selection to layout planning, our experts ensure every detail enhances your outdoor living experience.
Our skilled installers use high-quality materials and proven techniques to ensure your interlock surfaces are both beautiful and built to last. From initial design to final installation, we prioritize precision and craftsmanship to deliver results that exceed your expectations.

Interlock is one of the most durable surface options available for Ottawa properties. Unlike poured concrete, individual stones can flex with seasonal ground movement, reducing cracking caused by freeze-thaw cycles.
Interlock surfaces are also easy to repair — damaged or sunken stones can be lifted and reset without replacing the entire area, making long-term maintenance more cost-effective.
Sunken, uneven, or separating interlock doesn’t always need replacement. We offer professional interlock repairs, including lifting and re-leveling, base correction, joint sanding, and vintage stone restoration. This includes lifting and re-leveling sunken areas, replacing broken stones, correcting drainage issues, and restoring joints with fresh polymeric sand. Repairing existing interlock is often more affordable than replacement and can dramatically improve both appearance and performance.

Accurate grading is critical to preventing water pooling, erosion, and foundation damage. Our team performs precise grading and site preparation to promote proper drainage and create a stable base for sod, stone, interlock, or asphalt surfaces.
Fresh sod installation provides an instant, clean appearance for residential lawns and commercial properties. We prepare the base properly before installation to ensure even growth, strong rooting, and long-term durability in Ottawa’s changing climate.
In addition to soft landscaping, we install gravel and stone surfaces for laneways, equipment access, and drainage control. We also restore properties following paving, excavation, or utility work, leaving your site clean, level, and ready for use.
We supply and install high-quality topsoil to support healthy grass growth and long-lasting landscapes. Whether you’re repairing disturbed areas or upgrading an entire property, properly installed topsoil ensures strong root development and improved surface drainage.
The longevity of an interlock surface depends almost entirely on what’s underneath. At A1 Top Hat, we excavate to the correct depth and install a compacted granular base designed to prevent shifting, sinking, and frost heave.
Shortcuts in base preparation are the number one cause of failed interlock installations. Our proven process ensures proper drainage, stability, and long-term performance.
With proper base preparation and maintenance, interlock can last decades. Individual stones can be replaced without removing the entire surface. Interlock surfaces require minimal maintenance when installed correctly. Occasional re-sanding of joints, gentle pressure washing, and proper winter snow removal help keep your interlock looking new. With routine care, professionally installed interlock can last decades in Ottawa’s climate.
Periodic joint sand replacement and occasional re-leveling may be required, especially after harsh winters which here in Ottawa are prone to 4-5 freeze-thaw periods during winter.. That said - Proper installation will minimize maintenance needs.
Yes. Many interlock surfaces can be lifted, corrected, and restored at a fraction of the cost of replacement. So one of the biggest advantages of interlock is repairability is that individual stones can be lifted, adjusted, or replaced without removing the entire surface.
Sealing is optional. Some homeowners choose to seal interlock to enhance color and reduce staining, but it is not required for durability. The main advantage for sealing interlock is to prevent oil stains from entering deep into the porous cavities of interlock pavers. When properly sealed oil stains can simply be wiped clean in minutes. This is also a great DIY project that can be completed in an afternoon.
Now because our summers are high in humidity this work is best suited for dry fall conditions.
Interlock installation costs vary depending on stone type, pattern complexity, site conditions, and base preparation requirements. In the Ottawa area, most interlock projects fall within a moderate price range (Typically between $25 and $35 per sqft) compared to concrete, while offering superior longevity and repairability. We provide clear, upfront estimates so you know exactly what to expect before work begins.
