Optimizing negative buoyancy and pipeline protection while minimizing cost

Concrete weight coating provides reliable negative buoyancy as well as protection from harsh environments and mechanical damage that can occur—to both the pipe and its thermal insulation coating—during handling, transportation and pipe installation.

A concrete pipe coating can be applied over anti-corrosion and thermal insulation systems and applied in different densities to meet each project’s unique needs. Their excellent compression resistance meets the most stringent international specifications.

Production Process

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.

Pipeline Protection, Available Worldwide

Shawcor owns several mobile application plants that can be quickly mobilized for operation near any project site in the world—greatly reducing logistics costs.

Compression Coat

Compression Coat is a concrete pipe coating system that uses a side-wrap application process and is designed to provide negative buoyancy and mechanical pipeline protection in subsea and wet environments.



Wrapheavykote is a heavy concrete coating required to avoid buoyancy to underwater pipeline.



Concretkote is a heavy concrete coating required to avoid buoyancy for underwater pipelines.



HeviCote uses an impingement process to apply lightweight, normal weight and heavyweight concrete coatings, making it ideal for large-diameter pipelines.
