Generated explanation

Four cross sections compare mortar joint profiles between brick courses: concave, V-joint, raked, and extruded. Dashed circles highlight the exposed edges of the mortar joints. The concave profile has a curved recess, the V-joint an angular recess, the raked joint a deep rectangular recess, and the extruded joint projects beyond the brick face. Arrows indicate greater durability toward the left and lower durability toward the right. A bracket groups the raked and extruded joints as undesirable for exterior brick walls because they tend to trap moisture that can cause brick damage.
