StarTie
Wall tie for extending an existing wall or securing a new leaf to an existing wall
StarTie is the simple and cost-effective solution to the problem of securing new walls to existing walls.
StarTies are quick and easy to install and engineered from Grade 316 austenitic stainless steel. They are suitable for use in all standard cavity and solid masonry construction and have been designed to be driven into dry-pressed brick, extruded brick, block, aircrete, concrete, strong mortar, timber, stone and more.
StarTies may be used in hollow materials and close to edges. They are sufficiently flexible to permit normal masonry movement, are designed to shed water in cavity construction and provide strong, reliable axial restraint in both tension and compression...Learn more»
APPLICATIONS
- Connecting a new inner or outer masonry leaf to an existing wall.
- Connecting a stud wall to an existing masonry wall.
- Connecting a new masonry section in a damaged wall that is being taken down and reinstated.
- Creating a movement joint between an existing wall and a new wall.
- Joining a new party wall to an existing wall.
- Securing a wall extension to an existing wall.
FEATURES
- Grade 316 stainless steel tie.
- Slim, self-tapping, one-piece design.
- Small cross-section for stress-free installation and fixing.
- Effective in bricks, blocks, concrete, hard mortar and timber.
- Effective in brick veneer, cavity and solid wall constructions.
- Effective close to edges and usable in all weathers, temperatures and environments.
- Great axial strength.
- Flexibility to accommodate natural building movement.
BENEFITS
- Highly economical and easy to install.
- Multiple drip points prevent cross cavity water transfer.
- Helical design ensures excellent stress free mechanical connection and mortar bond.
- Can be installed through insulation without affecting its thermal performance.
- Range of standard tie lengths available to accommodate various cavity sizes.
BONDING AGENT
- None required.
INSTALLATION
Example Application: Connecting a new stud wall to an existing masonry leaf
-
Drill a small pilot hole, normally 5mm, through the stud and into the existing wall. (Pilot hole may not be required in low density block).
-
Load the StarTie into a Helifix driver attachment fitted to an SDS hammer drill.
-
Support the power driver with one hand, leaving the other to work the drill, and drive the StarTie into the hole to finish flush with or just beyond the face of the timber. (StarTies are self-tapping and will work themselves into the stud and wall following the hammer action of the drill.)
Example Application: Connecting a new masonry leaf to an existing masonry wall.
-
Drill a small pilot hole, normally 5mm, at an angle into into the existing masonry.
-
Load the StarTie into a Helifix driver attachment fitted to an SDS hammer drill.
-
Drive the end of the tie into the hole, before bending the exposed end of the tie down to lie flush with the top surface of the new leaf.
-
Bed the tie into the mortar of the wall during construction. Note: The exposed end of the tie may be sleeved to create a movement joint.
-
Points to Note
- The same procedures apply when adding a new wall to a solid wall, a cavity wall or a single leaf wall.
- StarTies are equally effective whether the new or existing wall is constructed from brick, block or stonework.
- If the ties are to be installed into existing mortar beds they must be sound and of adequate strength.
