Cementitious anchors are an alternative to epoxy
Cintec™ has been fully aware of the danger of fire and has always produced fire resistant remedial anchors and reinforcement.
Cintec™ has always been an advocate for the restoration of safe buildings through fire-resistant anchors. As long ago as 1993 fire tests were carried out by the internationally recognized Building Research Establishment in accordance with BS476, ISO, and CEN. The fire rig was designed for use in the measurement of the performance of Cintec’s™ anchors in a fire situation while subjected to a mechanical load which might be a result of wind suction of fire-induced thermal movement.
Cintec’s™ remedial anchors survived a two-hour test without failure of any of the samples. Every sample reached several hundred degrees in the part of the anchor nearest to the fire face. This indicates the anchor system can be recommended for repair work to buildings requiring a fire rating of up to two hours.
Cintec™ Anchors were later, unintentionally, put to the test at the Fullers Brewery in London. The Cintec™ anchor system had been used extensively to repair and restore the Brewery’s facade. A fierce fire followed, destroying large sections of the building. Despite the brickwork being subjected to extremely high temperatures, tests revealed that the cementitious Cintec™ anchors did not fail, performing to their original design.
They retained their integrity and could be reused for the repair work. If the anchors were an epoxy or resin type, they would have melted, releasing potentially dangerous fumes in the process and have been easily pulled out, allowing the wall to collapse. One could say that the Cintec™ Anchors having survived the fire are in fact fire proof.
Cintec™ anchors are the cementitious fire-resistant alternative to resin anchors. Since Cintec’s™ anchors are based on reliable restoration materials, cementitious grout and stainless steel, they easily provided the elusive fire rating typically absent in other systems.
