Interlock Paver Installation in Greater Montreal

Interlock pavers are the gold standard for Montreal outdoor surfaces because their modular design flexes with freeze-thaw ground movement rather than cracking like poured concrete. Our installation process follows a strict sequence that ensures decades of performance. First, we excavate to a depth of 12-16 inches depending on the application -- deeper for driveways that bear vehicle weight, shallower for patios and walkways. We install a geotextile membrane to prevent soil migration, then build up layers of compacted 0-3/4 inch crushed limestone in four-inch lifts, each compacted with a plate tamper. The final setting bed uses one inch of coarse concrete sand, screeded to a precise level. Pavers are then laid in the chosen pattern -- herringbone for driveways due to its superior interlock strength, running bond or basketweave for patios and paths. We cut border pavers with a diamond-blade wet saw for clean, tight edges. Polymeric sand is swept into the joints and activated with water to lock pavers together and resist weed growth and ant infiltration. We carry products from Techo-Bloc, Permacon, and Rinox, offering a wide range of colors, textures, and formats including slabs, tumbled cobblestones, and modern large-format pavers. Edge restraints are secured with 10-inch spikes to prevent lateral shifting over time.
