Which type of stabilization tools consist of wooden or plastic blocks that can be used to stabilize vehicles or debris?

Cribbing uses interlocking blocks—usually wooden or plastic—that are stacked to form a solid, stable platform under a vehicle or debris. The blocks are arranged to distribute the weight evenly and resist shifting, creating a rigid base that prevents movement as rescue or stabilization work continues. This method is chosen specifically because it provides a strong, customizable foundation right at the site, which is essential when parts of a vehicle or debris might roll or settle unevenly. Chocks, by contrast, are small wedges placed against tires to stop rolling; they don’t create a broader stabilized base. Buttress systems are engineered braces that transfer load to a different support point and are not the same as stacked blocks forming a crib. Nonhydraulic jacks lift or hold loads but don’t provide the continuous, distributed support cribbing offers.
