Concrete Weight Coating

Concrete Weight Coating is used for marine pipelines and river crossing for negative buoyancy and to counteract the effects of currents. Concrete is applied to pipelines to provide a negative buoyancy, which prevents the pipe from floating in high water table terrain such as swamp land.

Concrete Weight Coating (CWC) -

Concrete Weight Coating. Concrete weight coating (CWC) is a plant-applied reinforced concrete coating system externally applied by using either impingement or compression (wrap) method to either bare pipe or pre-coated offshore pipe with a minimum thickness of 25mm, intended primarily for submerged service for water or oil and gas pipeline system.


Coating thickness can vary from 20 mm to 150 mm. Concrete application provides pipe coating of uniform thickness with minimum deviations of specified weight. Concrete weight coating is applied to the exterior of steel pipe to provide negative buoyancy or mechanical protection for submarine pipelines.

Concrete Weight Coating | Shawcor

The concrete is prepared in an automated batching plant using aggregates (e.g., sand, iron ore), cement and water. The mix is applied on the pipe by impingement or compression while one or more reinforcing wire meshes are incorporated, depending on the required coating thickness.


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.
