Since its establishment in 1977, we, the pioneers of the grout-filled rebar coupler, have developed and released the NMB Splice Sleeve. The Splice Sleeve is ideal for the precast and cast-in-place construction industry, has excellent seismic resistance and fatigue performance, and does not require any personnel with special certifications to make the connection. The NMB Splice-Sleeve® is a mechanical grouted coupler for splicing reinforcing bars which uses a cylindrical shaped sleeve filled with a non-metallic, cementitious based non-shrink high early strength grout. Reinforcing bars to be spliced are inserted into the sleeve to meet approximately at the center of the sleeve. The interior of the sleeve is then filled with SS MORTAR grout. The NMB Splice-Sleeve® is a proven method for connecting precast reinforced concrete structural members. At the precast plant, the sleeves are embedded on one end of the precast element. The main reinforcing bars are inserted halfway into the sleeves with the bars protruding from the other end of the precast element. At the building site, the precast members are joined by inserting the protruding bars from the end of one precast member into the sleeves of the adjacent member. The sleeves are then grouted, in effect making the reinforcing bars continuous through the connection. This is called "Emulation" and the NMB is categorized as an emulative connection for precast systems.
