Why Choose Interlock for Your Patio?

Interlocking stone is a preferred material for patios due to its combination of aesthetic flexibility, durability, and easy maintenance. Unlike poured concrete or wood decks, interlock patios offer a more refined look, better drainage, and increased resistance to cracking and shifting. Over the years, we have become one of the leading GTA interlock patio companies serving our communities.

Benefits of Interlocking Stone Patios:

• Wide Range of Styles – Choose from a variety of colors, shapes, and patterns to create a unique design.
• Durable & Long-Lasting – Built to withstand foot traffic, furniture, and seasonal weather changes.
• Low Maintenance – Easy to clean, with individual stones replaceable if needed.
• Weed-Resistant – Polymeric sand between joints prevents weed growth and insect nesting.
• Great for Drainage – Allows water to drain naturally, preventing puddling and surface damage.

Ideal for Any Backyard Setting

Our custom interlock patios are perfect for:

• Outdoor dining areas
• Lounging and entertaining spaces

Our GTA Interlock Patio Installation Process

At DEMCON Design & Build, our company follows a tried-and-true process to ensure your patio is built on a solid foundation, both literally and aesthetically.

• Design Consultation: Our GTA interlock patio contractors start by discussing your goals, patio usage, and design preferences. Whether you want a cozy firepit area, BBQ zone, or a spacious entertaining space, we’ll guide you through layout options and stone selections.
• Site Preparation: We carefully excavate the designated patio area, ensuring proper grading and drainage. This step is crucial for long-term performance.
• Base Installation: Our company installs a deep gravel base, compacted in layers for strength and proper water runoff. This ensures the patio remains level and stable for years to come.
• Laying the Pavers: Interlock stones are installed in your chosen pattern, with professional alignment and spacing for a high-end finish.
• Joint Sand & Compaction: We sweep polymeric sand between pavers and compact the surface to lock everything in place, minimizing movement and weed growth.
• Cleanup & Inspection: Once the patio is complete, we clean the site, remove any debris, and walk you through the finished product to ensure your complete satisfaction.
