Strengthening an existing concrete structure through the use of shear dowels is a primary application of post-installed rebar. Though this is commonly done to improve the performance of concrete slabs and structures experiencing earthquake and seismic loads, the application is not limited to geographic areas experiencing these conditions.
A concrete anchor is a steel shaft either cast into concrete at placement or post-installed after the concrete has hardened. Cast-in anchors are threaded shafts with a buried end termination of a hex head, threaded nut, or 90 L- or 180 J- hook, or headed non-threaded studs welded to a surface plate.
