bed joint

The horizontal joint between two masonry courses.

concave joint

A recessed masonry joint formed in mortar by the use of a curved steel jointing tool; because of its curved shape, it is very effective in resisting moisture.

ground Joint

A closely fitted joint in masonry, usually without mortar; also a machined metal joint that fits tightly without packing or employing a gasket.

head joint

A vertical joint between two masonry units that is perpendicular to the face of the wall.

raked joint

A joint made by removing the surface of mortar with a square-edged tool while it is still soft; produces marked shadows and tends to darken the overall appearance of a wall; not a weather-tight joint.

rustic joint

In stone masonry, a deeply sunk mortar joint that has been emphasized by having the edges of adjacent stones chamfered or recessed below the surface of the stone facing.

struck joint

A masonry joint from which excess mortar has been removed by a stroke of the trowel, leaving a flush joint; a weather-struck joint.

tooled joint

Any masonry joint that has been prepared with a tool before the mortar in the joint has set rigidly.

troweled joint

A mortar joint finished by striking off excess mortar with a trowel.

v-shaped joint

A horizontal V-shaped mortar joint made with a steel jointing tool; very effective in resisting the penetration of rain.

weather-struck joint

A horizontal masonry joint in which the mortar is sloped outward from the upper edge of the lower brick, so as to shed water readily; formed by pressing the mortar inward at the upper edge of the joint.
