Since the early 1990s, Karlsruhe Institute of Technology's (KIT) Institute of Solid Construction and Construction Material Technology has modeled earthquake conditions to to find better ways to bolster walls, and this year scientists are producing seismic wallpaper that can keep walls stable. The product utilizes rigid, high-strength glass fibers woven together to form a strong, elastic covering. A flexible, soft adhesive generated from water and a large volume of polyurethane beads was manufactured by the KIT team in collaboration with the polymer makers at Bayer MaterialScience. Once the adhesive penetrates grooves in the masonry, the water evaporates to anchor the material to the wall. When the wallpaper is applied, it is fully surrounded by the beads. Bayer said in a recent press video that commercial production of the wallpaper will commence this year through partner companies.
