Cavity Ties

Made from 470gm galvanised wire or 316 marine grade stainless to conform to AS 3700 - 2011.

All wire used is either 3.15 mm or 4.00 mm diameter and these sizes have been used when tested to meet the requirements of AS 3700-2011.

A cavity tie is designed to tie together two leaves of masonry that are separated by a clear cavity of any width.

Length of ties is determined by adding Cavity Width + plus a minimum embedment of 50mm in each leaf as detailed in AS3700-2011.

Note: At least 50mm must be embedded into the mortar over each brick
