re-bar is a prestressing steel made of memory steel in form of a ribbed steel bar. The product is an efficient and easy-to-install reinforcement measure, especially for the strengthening of buildings. The material is pre-stretched by re-fer in the factory to a permanent deformation and delivered to the construction site according to the parts list. After roughening the substrate, or after making milling cuts, re-bar is fixed to the concrete. The system-tested mortar is then applied to the anchoring area. After hardening, re-bar is heated to >220°C with re-fer infrared radiant heater and pre-stressed. The area between the anchors is now poured out. The applied ribbed steel acts as an embedded system in the composite.
