Most houses in rural areas are low and wide. And the houses often have one or two floors which lack seismic ability. Based on the sufficient research of the steel asphalt isolation layer, we used the special isolation layer for a practical engineering case with three floors, and the isolation layer proved cheap with simple construction and obvious isolation effect. After the structure of the house was finished, we used the hammering method to test the isolation coefficient of the house by putting the vibration pickup style 941B on the basement floor and the first floor. The results showed that the isolation layer could decay the acceleration by about 40%. At the same time, the construction cost of the house did not increase any more at the contrast calculation. Therefore, this new type isolation layer is very suitable to be widely used in rural areas.
