Constructing Movement Joints (Cavity Wall)

Method Statement

1. Rake out or cut slots into horizontal mortar joints
2. Vacuum out the slots and thoroughly flush with water
3. Either:
a) Using the Bond Flex gun kit, insert a 10 mm depth bead of Bond Flex into back
of the slot or
b) Using the Polyester Resin gun, insert a 10 mm depth bead of Polyester Resin
into back of the slot
4. Place the length of plastic tube over one end of the Bar Flex to act as a sleeve
5. Push the complete assembly into the slot, obtaining good coverage
6. Insert a second bead of bonding agent (as in step 3) against the assembly
7. Seal the slot with a suitable flexible sealant and repoint
8. Tie inner and outer leaves together using appropriate Dri Flex or Retro Flex wall ties.

Guidelines

A. Depth of the slot to be 55 mm
B. Bar Flex to extend a minimum of 200 mm either side of the expansion joint
C. Alternate the position of the sleeve on adjacent ties
D. Ties to be installed at 300 mm vertical spacing
E. No bonding agent may come in contact with the Bar Flex in the sleeve as the Bar Flex must be allowed to move freely within the sleeve
F. Wall ties to be installed on each side of the newly formed movement joint not more than 225 mm back from the joint and at a maximum of 300 mm vertical spacing.
