A new method of repairing damaged structures by filling the cracks with a specially prepared polymer mass has been recently proposed. This new and innovative technique, known as the Flexible Joint Method (FJM), is mainly dedicated to masonries and historical objects, where minimum intervention is permitted. The flexible joint bonds the disrupted elements and ensures further safe exploitation of a damaged structure. The aim of the present paper is to show the results of the experimental study focused on determining the basic properties of the polymer mass used for the injections. The cylindrical specimens were subjected to static and dynamic testing. The results of the study indicate highly non-linear behaviour of the analyzed material. A clear correlation between strain rate and stress was observed. Finally, the hysteretic behaviour of the investigated material confirms its potential to dissipate the energy in case of dynamic loads.
