For residential and commercial construction projects located in high seismic risk zones, selecting the right wall material can make a life saving difference during earthquake events, and the EPS Cement Sandwich Wall Panel has proven to deliver far better earthquake resistant performance than traditional heavy brick walls. The extremely light weight of the EPS Cement Sandwich Wall Panel is its biggest seismic advantage: the total weight of the wall is less than one fifth of an equivalent solid brick wall, which means the total inertial force generated during an earthquake is drastically reduced. This dramatically lowers the load that acts on the main building structure during seismic activity, making the whole building far less likely to collapse.
During independent full scale shake table tests, buildings constructed with EPS Cement Sandwich Wall Panel can withstand magnitude 8 earthquake simulation tests without any major structural collapse or large wall fragments falling off. Traditional brick walls under the same test conditions usually break apart and generate large heavy falling debris that creates extremely high injury risk for people inside the building. The EPS Cement Sandwich Wall Panel stays intact even when the main building steel frame deforms slightly during an earthquake, as the panels are connected to the frame with flexible metal brackets that can absorb small structural movements without breaking.
Many local governments in high earthquake risk regions have now officially approved EPS Cement Sandwich Wall Panel as a recommended wall material for new residential reconstruction projects after seismic disasters. These projects report that buildings built with the panels can be completed in less than one third of the time required for traditional brick construction, while delivering far better safety performance. Homeowners living in these new panel buildings also report that they feel far less shaking movement during small aftershocks, compared to older heavy brick houses in the same area.
