Compression Coat™

Wrap-applied Concrete Weight Coating

Compression Coat™ is the leading concrete weight coating system for pipeline projects requiring coating at a client-preferred site. This concrete coating system is designed to provide negative buoyancy and mechanical protection for pipelines in subsea and wet environments. Compression Coat uses a side-wrap application process making it ideal for both small and large diameter pipelines. The product is available in various thicknesses and densities and can be applied over most anti-corrosion and insulation coatings.

  • Can be applied to a wide range of densities, thicknesses and strengths to meet project requirements
  • Available in thicknesses up to 150 mm (6”) providing a high level of mechanical protection and stability
  • Offers a more consistent thickness and smoother surface than impinge-applied concrete weight coatings
  • Can be applied over anti-corrosion and insulation coating systems.
  • Gentle wrap application reduces potential for holidays in FBE during coating
  • Can be enhanced with additional features including bendability slots and crack inducers as well as sacrificial anodes
  • Available from fixed coating facilities as well as portable plants that can be quickly mobilized to increase local content and minimize pipe handling and transportation costs
