Ties for Thin Joint Blockwork

Ties for Thin-Joint Blockwork

Staifix-Thor Helical TJ2 Wall Tie

Thin-joint construction prevents the use of traditional cavity wall ties requiring embedment in 10mm joints and coursing between the inner and outer leaves. The joints in the inner leaf of blockwork are reduced to 3mm or less by the use of special thin-joint mortar.

The TJ2 wall tie is ideal for thin-joint blockwork and other applications where the joints in the inner and outer leaves are not aligned. It is hammered directly into aerated concrete blocks, through insulation material, and is built into the bed joints of the outer leaf of brickwork.

This tie meets the requirements of PD 6697 as a type 2 or 3 tie depending on the block used and the cavity width. It can also be used in line with NHBC standards.
