On-Site Construction Operations

HydroFoamer BV is typically engaged by the Construction Contractor to perform polymer spraying operations in the field. Traditionally, this requires the Contractor to first install the pipeline, including clearing, trenching, and laying the pipe prior to foam application.

However, HydroFoamer’s system can also perform direct segmental lay-up of pipe sections, using integrated tools such as our patented collet inclinometer for precise angular alignment. This enables a flexible deployment model:

• Where desired, HydroFoamer can assume full responsibility for pipe positioning and foam encapsulation in a single integrated step.
• Alternatively, the Construction Contractor may pre-install the pipeline, with HydroFoamer focusing solely on the foam application.

The inclinometer ensures accurate rotational alignment of each pipe segment—including across slopes and curves—supporting controlled joint geometry and reliable installation data. This allows field deployment without large-scale jigs or external measurement teams, especially useful in mountainous, remote, or high-precision settings.

After foam application, a Civil Engineer (or surveyor) verifies compliance with the Technical Plan. Foam samples may be taken, and installation parameters—including pipe position and spray characteristics—are digitally logged. Backfilling is then completed by the Construction Contractor, in accordance with the Environmental Plan.

Governance and Risk Allocation

HydroFoamer’s expanded scope—from spraying to optional pipe positioning—requires clear operational boundaries and contractual clarity:

• When HydroFoamer performs installation, it assumes direct accountability for pipe positioning accuracy, using its inclinometer-guided workflow.
• When the Contractor performs installation, HydroFoamer operates as a spray-only subcontractor, with no responsibility for alignment.
• In both cases, quality control, site safety, and regulatory compliance are governed by the Technical and Environmental Plans.

Risk and liability remain clearly defined in each model. Foam application remains HydroFoamer’s core responsibility, and engineering authority continues to rest with the Civil Engineers.
