Other Info:
For a fast and low-cost way to finish the pilot holes after installation, use Titan Ties Injectable Repair Mortar. If an exact colour match to existing masonry is required, consider using SureStain Colour Matching Mortar.
SDS+ Drill Bits (for forming the pilot hole) are supplied as part of the kit- We sell 5.5mm diameter for 170mm-270mm ties and 6mm diameter for tie lengths of 300mm upwards. We can supply other diameters on request. Pro kits come with duplicate drill bits and setting tools.
Helical ties must have a minimum embedment in the inner (load bearing) leaf of 70mm
Pilot holes will be between 5.5mm and 6.5mm.
We recommend that you test the strength of substrate before choosing the appropriate drill hole
Above table assumes that facing brickwork is 110mm wide imperial brickwork (make adjustment for small widths / 100mm metric bricks).
Helical mechanical wall ties should be fixed into the centre of bricks- not mortar joints. The masonry should be sound. House covered in render / pebble dash? Consider resin ties if mortar joints are not visible or there are concerns about masonry condition.
Wall ties being replaced should be removed or isolated.
