Easy to construct, does not require large construction machinery, and can be done manually!
The "On-site Foam Polyurethane Lightweight Embankment Method" is a civil engineering technique that involves foaming rigid polyurethane resin "Formlight W" into shapes tailored to the terrain and structures, according to the required amount on-site. Due to its ultra-lightweight density of 36 kg/m3, it allows for the reduction of earth pressure and load in designs for embankments and soil structures. Since it is foamed on-site, it offers good workability and enables speedy construction. 【Features】 ■ Lightweight ■ Adaptability on-site ■ Stability ■ Workability ■ Cost-effectiveness ■ Adhesion *For more details, please download the PDF or feel free to contact us.

Company information
The Urethane Civil Engineering Technology Research Association is an organization aimed at further developing the R-PUR method of on-site foamed urethane embankment construction, improving technology, and promoting its use. The R-PUR method is a construction technique that forms embankments by foaming rigid urethane resin on-site. In addition to the material's ultra-lightweight, compressive strength, chemical resistance, heat resistance, and water resistance, it allows for the construction of embankments in free shapes that conform to the local ground conditions. It has already achieved construction results in various areas such as roads, bridges, and slopes, and its effectiveness is highly regarded.
