Strong Brothers Co., Ltd. has established a new construction technique Betakiso-Ippatsukun that uses a uniquely developed metal fitting and enables the raft (mat) foundation base and riseup in the process of building residential homes to be concreted in a single process. In general, the concreting of the raft foundation base and its riseup is accomplished separately in two stages, so that joints were generated frequently to impair the durabilities of these structures, so the newly established technique is anticipated to be adopted widely in the construction of housing units and buildings.
