Decorative Brickwork
Tumbling-In:
Definition:
A method of reducing the projection of an attached pier, or the width of an external chimney breast, by an inward sloping of the brick courses. These are laid at 90 degs. to the slope and cut to taper into the horizontal courses; the length of the tumbling should be divided into regular sections of three or four courses and lace into the horizontal courses to give a regular and pleasing effect. Care is needed in planning the number of sloping courses to the rise of the main wall and with the bonding arrangement. Tumbling-In allows the normal face side of the bricks to be used which provides a good surface to resist weathering.
