McArdent’s Ardent Earthbar FRP Rebar is a high-strength, non-corrosive Glass Fibre Reinforced Polymer (GFRP) reinforcing bar engineered for concrete structures in harsh, corrosive or chemically aggressive environments. Non-magnetic, non-conductive and completely corrosion-free — Earthbar eliminates the concrete spalling, cracking and structural failure caused by rusting steel rebar.As steel rebar corrodes inside concrete structures, the expanding rust shatters the surrounding concrete — a costly and dangerous failure mode in marine, coastal, chemical and wastewater environments. Earthbar FRP rebar prevents this failure mode entirely, delivering dramatically longer structural service life and lower lifecycle maintenance costs.Key Advantages Over Steel RebarZero Corrosion — Eliminates concrete spalling and cracking caused by steel rust expansionNon-Magnetic — Essential for MRI facilities, electrical substations and EMI-sensitive structuresNon-Conductive — Safe for concrete in electrical infrastructure applicationsLighter Than Steel — Reduces structural dead load and simplifies on-site handlingHigh Tensile Strength — Engineered for structural concrete reinforcement requirementsHelical Surface Wrap — Excellent mechanical bond with concreteApplicationsCoastal and marine concrete structuresWastewater treatment plant structures and tanksChemical plant concrete floors and containmentBridge decks in corrosive or de-icing salt environmentsMRI room and hospital concrete structuresElectrical substation concrete foundationsAvailable in 10mm, 12mm, 16mm and 20mm diameters.
