GRILLO-KKS-Beton is based on the experience of a development of more than 10 years. In test stands exposed to the atmosphere in an industrial and marine climate numerous preliminary tests were carried out with chloride-contaminated concrete samples. In addition to the examination of the basic system properties, such as coat thickness, adhesive strength and top coat systems, the potentials and currents are recorded in the test samples. On the basis of the measured values, readings can be made continuously and in a non-destructive way about the corrosion behaviour of the reinforcement. Thus, a constant diagnosis of the protection condition and preventive corrosion protection are possible for structures provided with GRILLO-KKS-Beton.

The evaluation of drilling cores  of the test samples confirms the results of these measurements and shows that after an exposure time of only six years a severe corrosion attack on the reinforcement occurs in non-protected samples. The samples protected by GRILLO-KKS-Beton did not exhibit any corrosion attack after this period with the parameters being equal.
