Cappings and copings are used to cap the tops of masonry parapets and freestanding walls to prevent rainwater from penetrating into the construction below. Irrespective of the materials from which they are made, a coping will project typically by 50mm on either side of the wall, whereas a capping will sit flush on the wall and so have no projections.

Because of their extreme position, cappings and copings are exposed to temperature extremes and frequent wetting/drying cycles. As they are more exposed than ordinary walling, they should be made of materials that have greater resistance to frost and sulphate action. To assist with water run-off, the tops of copings and cappings typically feature a slope – either a single- or double-slope.

Copings have projections to throw water as far as possible from the wall surface below. This is facilitated by the inclusion of drips – typically 10mm-wide semi-circular grooves cut into the underside of the projections – designed to prevent wind-driven rain from being blown against the wall.

In most cases, the coping/capping arrangement will not be completely water tight. Therefore, to avoid water penetration into the wall area immediately below, a damp-proof course is usually installed beneath the coping/capping.

Cappings and copings can also be made of profiled metal such as aluminium, zinc, copper and plastic-coated steel.
