  • Concrete weight coating

    Concrete is applied by wrapping a uniform layer while simultaneously wrapping reinforcing wire within the concrete coating for stability. The concrete is prepared in an automated batching plant using aggregates (e.g., sand, iron ore), cement and water. CONCRETE WEIGHT COATING CWC Bayou ,The concrete weight coating system is typically used in conjunction with other coating systems such as FBE and 3LPP/E. Bayou uses various methods to avoid slippage between the concrete layer and anti-corrosion coating. These include adding a rough-coat layer or applying a 2-component epoxy adhesive to bond the concrete to the coated surface.
