Earthquakes are highly dangerous for all masonry structures, as they force high deformations that brittle building materials cannot withstand. The solution to such problems may be the use of flexible polyurethane-based technologies (composite strengthening, adhesives etc.). On the other hand, these technologies are relatively new and demand experimental prove, whether they would not lose their properties after being subjected to environmental conditions i.e. temperature fluctuations, humidity, chemically aggressive mortars, solar radiation etc. Herein, we discuss the aspect of durability of PS polyurethane – the polymer used as both composite matrix and an adhesive in flexible protective technologies for masonry.
