Diagnose beneath the surface
Settlement and open joints are clues. Base, grade, drainage and restraint complete the picture.
A repair-focused division of A&Z Interlock
Interlock Repair Ottawa focuses on diagnosis, restoration and ongoing care for existing patios, walkways and driveways across the city.


Why this division exists
New installation and repair are different jobs. Repair begins with an existing pattern, existing elevations and a visible failure that may extend beneath the surface.
Our role is to determine what moved, why it moved and how much of the installation actually needs to be disturbed. When pavers remain sound, we aim to preserve them.
Explore our repair servicesOur working principles
The best scope is the one that addresses the cause and leaves stable areas alone.
Settlement and open joints are clues. Base, grade, drainage and restraint complete the picture.
Reusable pavers can return to their original pattern after the failed support is corrected.
A focused repair can make more sense than replacement when the surrounding installation remains stable.
Structural repairs come first. Joint renewal, cleaning and sealing follow when appropriate.
Ottawa conditions
Seasonal movement and drainage expose weak support. We look at how the property, transitions and edges affect the pavers—not just how the surface looks on one day.
