Welcome to the ELLIS MFG. CO. Reshore Spacing Calculator. This app can help plan reshoring projects when using Ellis Shores. The calculation method used follows the procedure outlined in ACI SP-4 (14) section 6.2. Paired with safe load data of Ellis Shores bases on actual load tests performed by a third-party engineer. These calculations show the spacing of reshores assuming no load is carried by the shore supporting slab, and it is transmitted to the next slab down.
