Reconnecting Brick Veneer to Wood Stud using DryFix®

Method Statement

  1. Locate the center line of the wood stud and then mark the position for the DryFix ties on the mortar joints. These should be positioned as shown below and not at the Head or ‘T’ joints.
  2. Drill an appropriate diameter pilot hole (depending on diameter of DryFix tie.  See Specification Note ‘C’ below) through the brick veneer only, using a rotary percussion drill (3-jaw-chuck type).
  3. Fit the special Power Driver Attachment (PDA) to an electric hammer drill (SDS type).
  4. Load the DryFix tie into the PDA.
  5. Power-drive the tie into position until its outer end is recessed below the face of the veneer by the PDA.
  6. Make good the entry hole with color matched materials to meet the requirements of the site.

Specification Notes

The following criteria are to be used unless specified otherwise:

  1. Length of DryFix ties to be sufficient to accommodate width of brick veneer + width of cavity + 2” into the wood stud
  2. Pilot hole through brick veneer only
  3. Diameter of pilot hole to be determined on site – typically:

    (5-6mm for 8mm diameter tie) or (7-8mm for 10mm diameter tie)

  4. Fixing centers will be determined by the stud spacing and required fixing density

Reconnecting Brick Veneer to Hollow Concrete CMU using DryFix®

  1. Mark the position for the DryFix ties on the mortar joints.  These should be positioned as shown below and not at the Head or ‘T’ joints.
  2. Drill an appropriate diameter pilot hole (depending on diameter of DryFix tie and density of back-up material.  See Specification Note ‘C’ below) through the veneer and into the back-up substrate, to a predetermined depth, using a rotary percussion drill (3-jaw-chuck type).
  3. Fit the special Power Driver Attachment (PDA) to an electric hammer drill (SDS type).
  4. Load the DryFix tie into the PDA.
  5. Power-drive the tie into position until its outer end is recessed below the face of the veneer by the PDA.
  6. Make good the entry hole with color matched materials to meet the requirements of the site.

Specification Notes

The following criteria are to be used unless specified otherwise:

  1. Length of DryFix ties to be sufficient to accommodate width of brick veneer + width of cavity + wall of CMU + 1”
  2. Ensure pilot hole goes right through the wall of the CMU
  3. Diameter of pilot hole to be determined on site – typically:

    4. (5-6mm for 8mm diameter tie) or (7-8mm for 10mm diameter tie)

  4. Tie spacing to be determined by the project engineer in accordance with individual site conditions
