Tie Length & Density
Wall ties should be of the correct length to ensure they are properly embedded in the masonry. Leviat recommends tie lengths which achieve an embedment of between 62.5mm and 75mm.

1. Inner leaf masonry thickness 70 to 150 mm for cavity walls.
2. Around openings and at control joints, the vertical tie spacings are halved (ie the number of ties must be doubled).
3. In veneer construction, masonry must be tied to stud wall framing at all regular stud positions, including gable ends.
The spacing of veneer ties should be in accordance with building codes or engineers' specifications. There should be a minimum 15mm cover from any exposed surface.
Remedial Wall Ties
No standard has yet been defined for the spacing of remedial wall ties. However, accepted practice is to follow AS 3700.
