INTRO

The HydroFoamer system is protected by a structured international intellectual property portfolio covering the installation method, application system, and sector-specific use cases.

At its core is Dutch patent NL2014216B1, which forms the basis of a broader patent family across multiple jurisdictions, including the United States, Eurasia, Nigeria, and Mexico.

CORE PATENT

The core patent protects the use of rigid polymer foam as a structural backfill system for GRP pipelines.

It covers the replacement of conventional granular materials and concrete thrust blocks with a continuous foam-based support system in both straight and curved pipe geometries.

EXTENSION PATENTS

The platform is further protected by additional patents that extend the system into deployment and new sectors:

Robotic Application System

Covers the mobile spray platform, including controlled field application of structural foam and integration with installation and quality control processes.

Oil & Gas Applications

Protects the use of foam encapsulation for steel pipelines in demanding environments, including high-pressure and chemically aggressive conditions.

This includes protection against corrosion, uplift, and lateral instability, as well as the use of native or marginal soils as backfill.

KNOW-HOW

Beyond formal patents, HydroFoamer holds significant proprietary know-how.

This includes:

• Simulation models for foam–soil–pipe interaction

• Validated field data from full-scale installations

• Engineering methods for thrust resistance and load distribution

• Practical deployment knowledge under real site conditions

This body of knowledge is essential to successful application and is not captured in patents alone.

COMMERCIAL POSITIONING

HydroFoamer is not a single patent, but an integrated system combining method, equipment and engineering practice.

Replication requires:

• access to protected IP

• understanding of foam behaviour in geotechnical conditions

• control of installation methodology

• validated field experience

As a result, the system forms a defensible platform for deployment across multiple pipeline sectors.
