Patent ID: 8752355

Claim:
A method of stabilizing a building against earthquake damage, the building being constructed with a wall made of stacked rows of hollow core blocks, the hollow core blocks being made of concrete, cindercrete or clay, the hollow core blocks having cores stacked to form hollow channels extending upward through the wall, the method comprising: reinforcing the wall by creating respective injection ports in or between shells of selected hollow core blocks, in which each injection port provides an injection point for a corresponding hollow channel extending upward through the wall, and injecting expanding polymer resin into the corresponding hollow channels of the wall through the respective injection ports to fill the corresponding hollow channels to create filled channels but not injecting expanding polymer resin through an injection port into each hollow channel of the wall such that there are unfilled hollow channels that are not filled with expanding polymer resin, with at least some of the filled channels being adjacent to and connected by openings to a corresponding one of the unfilled hollow channels, the expanding polymer resin being injected into the at least some of the filled channels to fill the cores of the filled channels and flow over into the openings to bind the hollow core blocks together.
