FAQ
Frequently asked questions
Is HydroFoamer a trenchless method?
No. HydroFoamer is a controlled installation method for buried pipelines using sprayed PU foam support.
Does HydroFoamer replace the pipe?
No. HydroFoamer changes the installation system around the pipe. The near-term focus is on composite pipe systems.
Does it work only with composite pipe systems?
The near-term focus is composite pipe systems. Broader applications may require project-specific qualification.
Does it eliminate all imported aggregate?
No. HydroFoamer can significantly reduce dependency on imported bedding and embedment material, depending on project design, trench conditions, pipe system and local requirements.
Is the foam structural?
Yes. The method uses structural polyurethane foam as part of a defined support and restraint geometry.
Is every project suitable?
No. Suitability depends on pipe type, diameter, trench conditions, loads, design requirements, logistics, installation method and regulatory context.
How is the business case calculated?
The business case is calculated using PACE, based on project geometry, logistics, material quantities, production assumptions, cost inputs and CO2 factors.
What makes HydroFoamer different from conventional installation?
Conventional installation often treats imported bedding, embedment, compaction and material handling as unavoidable. HydroFoamer tests that assumption by using engineered sprayed PU foam, measured installation control and auditable as-built evidence to reduce construction activity and improve installation certainty.
