While many existing practices for structural health monitoring (SHM) solutions heavily rely on tethered (wired) systems, our sensors are wire-free and non-destructive. Our online monitoring system, based on new technologies, collects and analyzes precise information that leads to proactive long-term maintenance systems.
Installation of the corrosion sensor above the reinforcement (corrosion attack from above) prior to concrete placement.
A minimum concrete cover of 0.6 inch (15 mm) from the upper edge of the sensor must be observed for quality of C20/25. For higher concrete strength classes from C40/45, the value can be reduced by 5 mm.
Fastening of the corrosion sensor underneath/behind the reinforcement (determination of the effect of, e.g., remaining chloride-contaminated concrete after repair = corrosion attack from below). The sensor itself is to be embedded in a coupling mortar, after which the repair site is closed in accordance with the recognized technology rules (e.g., with plastic-modified mortar).
Fixing of the sensor by means of a core hole drilling, filling with coupling mortar, and finishing (depending on the position) with a mechanical sealing system or shrinkage-free plastic-modified mortar. The subsequent mechanical load situation and the corresponding after-treatment of the surface must be observed in accordance with the current regulations. In the case of a final coating, the coupling mortar can be applied to the surface.
