| Property | CD Reef V4 (2021) | Generic EVA Foam (30 kg/m³) | Cork/Rubber Blend | | :--- | :--- | :--- | :--- | | Dynamic Stiffness | 18 MN/m³ | 55 MN/m³ | 35 MN/m³ | | Long-term creep (20 yrs) | < 2% | 15–25% | 8–12% | | Recycled content | 85% | 0–10% | 40% | | CSTB 2021 certified? | Yes | No | Varies | | Suitable for heated screed | Yes (≤60°C) | No (softens) | Yes (≤50°C) |

CD Reef distinguishes itself from standard coastal design tools by integrating with fluid dynamics. This allows engineers to visualize the movement of individual stones or armor units rather than treating the structure as a continuous mass. cd reef v4 cstb 2021
