DESIGNING FOR MOVEMENT IN BRICKWORK

1. In general, experience suggests that movement joints in clay brickwork should be spaced at approximately 10 - 12 metres. PD 6697 states that in no case should joints exceed 15 metres and the spacing of the first joint from an internal or external angle should not exceed half of the general spacing.

Movement joints are constructed within masonry to accommodate predicted volume changes of the masonry materials as well as relative movement between masonry and adjacent materials. Movement joints are finished with sealant to prevent water entry while the joint changes dimension. Masonry movement joints may be described as one of three types: expansion joints, contraction or control joints, and isolation joints.

When to use expansion joints in brickwork

Apr 30, 2015 · Movements joints and their size vary depending on the size of the wall. 1.3mm per linear run of brickwork should be allowed, so a wall that has movement joints at 9m centres should have a joint of 12mm. These principles generally apply to both horizontal and vertical joints. High walls tend to experience greater movement towards the top of the wall, than in the lower extremities. This is …

CONTROL JOINTS FOR CONCRETE MASONRY …

Movement joints such as control joints are one method used to relieve horizontal tensile stresses due to shrinkage of the masonry units, mortar, and when used, grout. They are essentially vertical planes of weakness built into the wall to reduce restraint and permit longitudinal movement due to anticipated shrinkage, and are located where stress concentrations may occur. A bond break is accomplished by replacing all or part of a vertical mortar joint …
