Creating Movement Joints

Creating movement joints

Using 16” long HeliBars, together with DryFix retrofit ties, creating movement joints in existing walls is very simple. The appropriate number of DryFix ties are installed either side of the proposed joint. Horizontal slots are then cut, to the required depth and vertical spacing, across the planned movement joint. A vertical slot is then cut in the outer wythe between the two columns of DryFix ties.

Resin is injected into the horizontal slot and a de-bond sleeve is fitted over one half of the 16” HeliBar before the complete assembly is pushed into the slot, bonded and re-pointed. The sleeve at one end and the HeliBar at the other are bonded into the masonry but the HeliBar is left free to move inside the sleeve.
