Crack Stitching & Helical Bars
For lasting crack repairs, stainless steel helical bars are used to reconnect and reinforce cracked brickwork. These helical spiral crack stitching bars are bonded across cracks in masonry using a cementitious grout or polyester resin. Our masonry repair systems have been trusted by professional installers for years as they are strong, durable & fast to install
How to Install Helical Bars
Strong, durable and fast to install, the Titan Ties Crack Stitching System is a permanent
and non disruptive repair that eliminates the need to rebuild a wall.
Titan Ties helical crack stitching bars and helicoils are manufactured from Grade 304 (A2) austenitic stainless steel,
providing a lasting combination of axial strength and flexibility.
Our SureGrout or styrene free polyester resin provide excellent bonding characteristics within the masonry, acting
compositely with the helical bars to absorb localised stress and minimises the likelihood of further cracking

Please provide your details below and a local specialist will be in touch.
What is crack stitching and how does it work?
Crack stitching is a structural masonry repair method that strengthens cracked brickwork by installing stainless steel helical bars into cut slots across the crack and bonding them in place with a grout or resin. This helps reconnect the masonry and distribute tensile forces along the wall.
What types of cracks is crack stitching suitable for?
Crack stitching is commonly used for stair-step cracks in brickwork, horizontal cracking, and localised structural cracks caused by movement, settlement, or thermal changes. If cracking is ongoing or widening, you should get the cause assessed before repair.
Do I need a survey or design before crack stitching?
Not always. For straightforward, non-progressive cracking, many repairs can be specified from photos and basic measurements. For more serious cracking, repeated cracking, or structural concerns, we can arrange surveys and repair designs through our network of approved engineers and specialist contractors.
What products do I typically need for crack stitching?
Most crack stitching repairs require: Stainless steel helical bars, A bonding medium (cementitious grout or resin), Installation tools (slot cutting, pointing tools, mixing/application tools). We can advise the correct bar diameter/length and bonding method for your wall type and crack pattern.
Should I use grout or resin for crack stitching?
Both work, but they suit different situations:
Grout is more tolerant of thermal movement and is the only system that we would recommend for lime mortars
Resin can be useful for small DIY projects as it is quicker and simpler to install (no mixing of grout)
We’ll recommend the most suitable option based on your wall construction and site conditions.
Can crack stitching be done on external and internal walls?
Yes. Crack stitching is used on external brickwork and internal masonry. The correct approach depends on access, finishes, wall type, and whether the crack passes through full thickness or is localised.
How many bars do I need and where should they be installed?
Bar spacing and layout depend on crack type, wall thickness, and load paths. Our Titan Ties Crack Stitching Installation video gives typical spacings.
Can you supply kits and provide technical advice?
Yes. We supply crack stitching components and can provide technical product guidance on selection, installation best practice, and compatibility with your masonry.
