CD Reef v4 refers to a specific version of a numerical modeling software used for the simulation and analysis of breakwaters and coastal structures. The "CSTB 2021" designation indicates that this version was either released, validated, or significantly updated in 2021 by the CSTB (Centre Scientifique et Technique du Bâtiment), the French Scientific and Technical Center for Building.
This software is a specialized tool used in coastal engineering to predict the stability of armor layers (rock or concrete units) under wave attack, moving beyond traditional empirical formulas (like Hudson or Van der Meer) by using a Discrete Element Method (DEM) approach. cd reef v4 cstb 2021
CD Reef V4 is a fourth-generation resilient acoustic underlayment, primarily manufactured for use under cementitious and anhydrite screeds. Unlike traditional foam or rubber underlays, the "Reef" series utilizes a high-density recycled elastomer matrix, often incorporating granulated rubber bonded with polyurethane resins. The "V4" designation signifies the fourth version of this product line, incorporating improvements in compression resistance, thermal conductivity, and long-term creep behavior based on feedback from prior installations.
