What is the maximum height difference between interlocking pavers?

• A. 3/16 inch
• B. 1/4 inch
• C. 1/16 inch
• D. 1/8 inch

Answer: (D)

Maintaining uniform height across interlocking pavers is essential for a stable, flush surface and proper interlock. Small height differences can cause uneven seating, misalignment of joints, and trip hazards, and over time can stress the base and edge restraints. The maximum allowable height difference between adjacent pavers is 1/8 inch, which provides enough tolerance for minor variations in paver thickness and base preparation while keeping the surface even and the joints consistent. A tighter limit like 1/16 inch is stricter than necessary, while larger gaps such as 3/16 inch or 1/4 inch would produce noticeable steps and could compromise performance.
