Interlocking paving is a misleading term. What actually constitutes interlocking is really a dynamic function containing three different componets. They are "rotational interlock" (resistance to tipping) "horizontal interlock" (resistance to spreading) "vertical interlock (resistance to sinking)". So, that means for lasting quality you need good containment, good subbase and proper paver thickness. Thicker pavers for driveways thinner pavers for patios. |
