Polymer Resin Concrete (PRC) replaces the cement binder of ordinary concrete with a high-performance resin system, producing a denser, stronger and completely corrosion-proof material.
PRC is made by binding graded aggregate and silica sand with a thermosetting resin instead of Portland cement. The resin fully coats and locks together every particle, leaving virtually no pores for water, gases or chemicals to travel through.
The result is a composite that reaches around 120 MPa compressive strength with no steel reinforcement. Because there is no rebar and no cement, there is nothing inside the material for sewage gases, chlorides or acids to attack — so it simply does not corrode.
PRC also cures in about an hour rather than the days traditional concrete needs, so units can be produced and put into service far faster. The finished products are considerably lighter than precast reinforced concrete, which makes them easier and safer to transport and install.
For infrastructure exposed to harsh, corrosive conditions — sewage and drainage networks, coastal and saline ground — PRC delivers a service life of 100+ years with minimal maintenance. You can read more on our Technology page.
