Part 4 of the “Designing with Strength” series for landscape architects and designers Previous post in this series: Holding the Line: Edge Restraints and the Art of Durable Paver Design Note: This series of articles is intended to provide an introduction to the concepts behind paver design for designers.

Every successful pavement begins long before the first paver is set. Beneath the surface lies a quiet structure of layers—soil, aggregate, sand—each one playing a role in supporting the next. While the surface pattern catches the eye, it’s the unseen foundation that determines how that design performs through time, weather, and use.
