Enhancement Rods

GRUENSTARK Enhancement Rods (GS-E) are the most sophisticated structural enhancement bars available on the market today. Incorporating available features such as a unique geometric fastening mechanism, cold-worked stainless steel, specially designed fabric components, compatible injection materials, and an optional injection core, the GS-E line provides maximum security across its many applications. GRUENSTARK’s enhancement rods are thoroughly proven in the field, with thousands utilized on critical preservation and enhancement projects around the globe. Installation is minimally invasive and entirely reversible via over-coring. Moreover they are completely invisible when installed.
