Car park monitoring that makes chloride damage visible early.

Car parks and underground garages are exposed to particular stress: de-icing salt from winter operation, moisture from wet vehicles and exhaust fumes attack the reinforced concrete. Chlorides penetrate the concrete, trigger reinforcement corrosion and lead to unnoticed cracks and spalling. Car park monitoring makes these processes visible early and prevents an inconspicuous defect from turning into an expensive full refurbishment.

Moisture and corrosion sensors, and crack transducers where needed, are installed at the critical areas, for example at drainage low points, at columns and at heavily used parking spaces. The sensors capture moisture, corrosion progress and crack widths. The readings are stored and evaluated, so the responsible party can track the condition at any time and determine the optimal refurbishment timing.

Yes. Especially during refurbishment, monitoring provides evidence that the measures are working. Sensors document the condition before, during and after the refurbishment and show whether moisture and corrosion events are declining. This allows a targeted refurbishment to be steered instead of refurbishing a large area out of uncertainty.

Yes, and this is often the most economical solution. If moisture and corrosion sensors are installed already during the new build, they monitor condition from day one, secure build quality up to acceptance and beyond, and later enable targeted instead of blanket refurbishment. Preventive moisture monitoring is especially useful for covered, inaccessible roof seals.

The focus is on the areas with the highest damage risk: drainage low points and drainage joints where moisture collects, entry ramps with high salt and moisture ingress, load-bearing columns and the most heavily used parking spaces. Hard-to-reach maintenance shafts can also be included in the monitoring.

Because damage is detected early, refurbishment can happen while the effort required is still low. Instead of an expensive full refurbishment after years of unnoticed progress, a targeted, localised intervention is often sufficient. Closure times for users are also reduced because the refurbishment becomes plannable and precisely scoped.
