Pier support is a term used to describe the structures that are used to support piers, which are structures built over water. The three solutions for this term are PILE (4 letters), Gabion (6 letters), and PILING (6 letters). A PILE is a vertical structure made of wood, steel, or concrete that is driven into the ground to provide support. A gabion is a wire mesh container filled with rocks or other materials that is used to provide support. PILING is a type of foundation that is driven into the ground to provide support. All three of these solutions are commonly used to provide support for piers.
