Helix Spiro Drive Ties (timber)
Timber Frame Construction
TYING WALLS TO NEW CONSTRUCTION
Easy To Install. Strong. Permanent
No
other system anchors masonry to concrete block, concrete backup or wood
studs as quickly, economically and securely as Spiro-Ties. Manufactured
from Type 304 austen.itic stainless steel to provide excellent corrosion
resistance, Helix Spiro-Ties are easily hammer-driven into the substrate,
where they tap a threaded channel to produce a hold that is strong and
permanent.
Helix Spiro-Ties come in various lengths and two standard diameters of 5mm and 7.5mm with a metal thickness of 2mm. They are ideal for use in residential, institutional or commercial buildings featuring exterior masonry cladding.
The high-performance Spiro-Ties system fits through insulation with no loss of thermal properties.
A custom-crafted tool ensures that when installed correctly, each Spiro-Tie can be driven to its specified embedment in poured concrete or unit masonry as well as into wood stud backup.
Advantages
The advantage of Helix Spiro-Ties over alternative systems include:
- effectively resists tension while accommodating sheer and compression forces
- allows for vertical and horizontal movement
- accommodates an adjustable Vista-Fix insulation retaining disc
- has multiple drip points to prevent moisture transfer across the cavity
- allows for variation in joint coursing between wythes
- resists corrosion, degradation and fire
- meets or exceeds Canadian, British and USA standards

Installation
Helix Spiro-Ties installation is quick and easy, following these simple guidelines:
- Prepare the inner wythe surface by pre - drilling substrates of poured concrete or masonry. No preparation is necessary to wood stud backup.
- Load the Spiro-Tie into the drive tool barrel, which is specially designed to accommodate the specified tie embedment depth Place the Spiro-Tie at its desired point of entry and drive it into place with a hammer.
- Test the strength of the installed Spiro-Tie embedment with a load test unt.
- Install a Vista - Fix insulation retaining clip to sec~:’~ insulation.
- Spiro-Ties must be built into the bed joint as th~ exteiior cladding courses are laid to meet the embedment specifications
- Place Spiro-Ties with a slight fall toward the outer wythe, taking normal precautions to prevent mortar dropping from collecting on the ties below.
- Placement and location must be in accordance with applicable standards and project specifications.
- A project engineer must specify the precise embedment positioning of Spiro-Ties
- Spiro-Ties should be installed by qualified contractors and installation must be approved by the project engineer.
