About Us

We use creative polyurethane foam solutions to install buried pipelines and thrust blocks. Our solutions are much quicker than traditional gravel-based backfill, with at least 7 times greater geotechnical stability. Backed up by strong IP, unrivalled academic studies, and our first project for the Norwegian hydropower giant Statkraft, HydroFoamer revolutionises pipe installation with a self-contained, state-of-the-art robotic sprayfoam platform that can install a 10km / 6 mile typical GRP pipeline in around 2 weeks.

Our History

HydroFoamer started life as a project in Norwegian hydropower in 2014, based on a cost reduction initiative.

Our Product

HydroFoamer is a self-contained, portable automated spray platform that very rapidly apply a layer of closed-cell, rigid polyurethane foam to a pipe system.
