What is tongue and groove composite decking?

Tongue and groove decking is made of wood or composite boards that have a groove along one edge. The dream deck has a tongue and groove, which is a long groove on one side and a bump on the other.

The tongue and groove profile is cut so that it fits snugly into the groove of the next plank. Both the tongue and the groove are cut to fit the whole length of the floor. This lets the planks fit together like pieces of a puzzle to make a flat surface.
