A tie or tie is a union made with rope, wire, chain "Chain (object)") or any other material that allows ligations to be made to secure and hold two or more elements.[1]​.

square lashing

Square lashing is a joining method used for two poles placed crosswise, so that one holds the other. There are several types, but they all consist of making several turns around the stringers and then securing the line that runs between them by means of strong knots.[2]​

The most commonly used knot for this type of mooring is the leaf lashing.[3]​.

Diagonal mooring

Diagonal lashing is used to join posts together and prevent them from moving. It gets its name from the fact that the wraparound turns cross the posts diagonally and are used to join them together where they do not touch, such as in the "X" support of a trestle.[4]​.

Mooring in eight

The figure-of-eight tie (two-stringer shear tie) is used to join two parallel posts that open in an “A” shape. The crossbow knot is tied only around one post and is looped between the two posts. It is used, for example, to make rafts, tables and bases for elevated camps.[5]​.

round mooring

The round tie is used to tie two poles together so that one is an extension of the other, to make a mast, for example.[2][6][4]​.

Tripod tie

The tripod tie is used to create a tripod, and is also a base for making more complex structures.[2]​.
