BrickFix DriveTie Helical Wall Ties
BrickFix DriveTie helical wall ties provide a simple and fast method of installing wall ties into existing cavity walls – e.g. where the original wall ties have corroded or were installed incorrectly.
They are manufactured from 304 grade stainless steel bar (316 grade available on request) and are driven into masonry using a special drill attachment.
BrickFix DriveTie helical wall ties are available in various lengths to accommodate different cavity widths.
Wall Tie Installation
DriveTie helical wall ties are installed using a special fixing tool that attaches to an SDS drill as shown in the diagrams below:
Step 1Drill the pilot holes through both leaves to required depth and diameter.
Step 2Insert the installation tool into an SDS rotary hammer drill, then place the tie into the installation tool.
Step 3Drive the tie into the internal leaf to the required depth ensuring the tie is fully recessed to the external leaf below the face of the masonry.
Step 4Make good the tie at the surface with Colour Pointing Mortar.
All BrickFix wall ties should be installed in accordance with the advice given in BRE Digest 329 and BRE Digest 401. If you would like to discuss a wall tie replacement project, please contact our technical department.
