Tile Creasing

As an alternative to a brick oversailing course, one or two courses of creasing tiles can provide the overhang, with the weathering completed with a mortar fillet (see Fig 207). Creasing tiles are rectangular, plain, flat, clay tiles that measure 265 x 165 x 11mm, available in a number of colours such as brown, red and blue brindle. The size and flat nature of the tiles allows a larger overhang (up to 40mm) to be created, which ensures a better weathering to the wall.

On both single – and double-course tile creasings (see Figs 225 and 226), all bed joints are 10mm and cross-joints should be as tight as possible and no more than 3mm. Where a double course of tiles has been used, the tiles should be overlapped or half-bonded, for structural strength and water resistance. The methods of laying, levelling and running-in courses of creasing tiles are exactly the same as those used for brickwork

Some bricklayers take the view that the straight finish of creasing tiles is rather dull. The decorative effect may be enhanced by using clay roofing tiles with nibs as a single course under the brick-one-dge coping.

If required, it is also possible to create a double-course creasing by running a course of plain creasing tiles, in a matching colour, on top of the course of nibbed tiles. If using clay roofing tiles in this way, it is wise to select tiles that do not have too much of a surface camber, as this can make laying and levelling rather difficult.

It is good practice with a tile creasing, as with an oversailing course, to extend it at a stopped-end in order to provide a weathering and protection to the stopped-end brickwork.
