ConcProt shows that the distance between the reinforcement and the formwork is less than the required 50 mm and the concrete protective layer would be too thin.

Measurement with the largest ConcProt. Compared to other vertical gauges, this model is bigger and has “teeth” with smaller width.

Concrete thickness measurement with the largest vertical ConcProt.

Example 1: Insufficiently thick protective layer can cause concrete to carbonize as the concrete structure ages.

Example 2: The rust layer on the reinforcement pushes out the concrete protective layer covering the reinforcement by expanding and the reinforcement remains open to weather conditions.

Example 3: Corrosion and expansion of the reinforcement caused by a protective layer of insufficient thickness can lead to the release of larger pieces of concrete from the structure.
