Cribbing is used when the structure needs to be jacked up from its foundation. Cribbing involves building a crib of wood timbers in a Jenga type formation in key spots underneath the building. The cribs will provide support to keep the building up when it is lifted from its supporting columns.
Cribbing is also used for mining and landscaping.
