Oversailing Courses at Stopped-Ends of Walls

For boundary walls where there is no attached pier at the end of the wall (or where the pier has been terminated below the top of the wall), consideration must be given to extending the oversailing course beyond the end of the wall,

in order to provide a protective weathering to the stopped-end brickwork.

Brick-on-Edge Copings with an Oversailing Course

Whether there is an oversailing course present or not, the method adopted to construct a brick-on-edge coping is the same. Where there is an oversailing course, however, the bricklayer must make sure that the brick-on-edge is set back from the edge of the oversailing course a distance equal to the projection of the oversailing course. In other words, he or she must ensure that the brick-on-edge coping effectively sits on top of the main wall. This can be achieved by simply turning over the home-made wooden gauge and using it to measure how far to set the brick-on-edge back from the front face of the oversailing course.

 

If the oversailing course is finished flush with the stopped-end, the stopped-end brickwork is left vulnerable to

 

the vagaries of the weather. Good practice, therefore, dictates that the oversailing course should be made to overhang beyond the stopped-end of a wall in order to provide a weathering (see Fig 233). An overhang at the end, however, does mean that the length of the oversailing course will exceed the length of the original wall. As a result, cuts or a broken bond will need to be introduced in the middle of the oversailing course so that the bond is maintained. Also, where any oversailing course is visible at the stopped-end of the wall, a cut must be introduced at the end to close the visible gap between the front and back oversailers (see Fig 207). The enlarged collar joint along the wall length between the front and back of the oversailing course is commonly filled with mortar, but it is good practice to in-fill with cut bricks.
