A new method of repairing damaged structures by filling the cracks with specially prepared polymer mass has been recently proposed. The technique is mainly dedicated to 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 an experimental study on polymer mass used for the injections. The specimens made of polymer mass was subjected to static and dynamic testing. The results of the study indicate highly non-linear behaviour with relatively low resistance under small displacements and a stiffening effect for the higher strain levels. A clear correlation between strain rate and compressive stress was observed. Finally, the hysteretic behaviour of the material confirms its potential to dissipate energy during vibrations and prevent against further structural damage in case of dynamic loads.
