What Is HPB? Interlock Layer Structure Explained
Detailed information about HPB (High Performance Base) and the role of interlock installation layers.
What Is HPB (High Performance Base)?
HPB is the high-performance subbase material used in interlock installation. It is critical for load capacity and drainage.
Layer Sequence
From top to bottom: Paver (stone) → HPB → Gravel → Soil. Each layer contributes to a long-lasting structure.
Why It Matters
Missing or incorrect layer structure leads to settling within 1–2 years. StoneRevive applies standards-compliant layers on every project.
