What water pressure will Radcon handle prior to failure?

Radcon has undergone several such tests. Probably the SINTEF Norway test showing Radcon maintaining a watertight seal under a 400 metre pressure head would be the most significant to date.
In fact it was the actual failure of the cracked Radcon treated concrete cylinder under a 400 metre pressure head which concluded the SINTEF published result.
