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. 

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.

Grade 304 (A2) ties are sold as standard- consider Grade 316 (A4) in highly corrosive areas such as marine locations or heavily polluted industrial environments. All products can be upgraded on request.

Wall ties being replaced should be removed or isolated.
