Helifix Movement Joints
HeliBar stainless steel helical bars in conjunction with plastic debonding sleeves can be used to create a movement joint in an existing wall.
The 6mm diameter HeliBar is available in either austenitic stainless steel Grade 304 (1.4301) or 316 (1.4401) and is supplied in a standard length of 400mm for this application. The sleeve is 200mm long to debond half the bar, allowing movement to take place at the joint.
The HeliBar restrains the masonry against lateral loads whilst the sleeve allows the masonry to expand and contract.
The HeliBar-sleeve assembly is installed in cut slots which cross the location of the new movement joint, with the sleeve part positioned on alternate left and right sides of the bar.
