Over time, the Romans developed several techniques for the covering of concrete:

Opus incertum: small irregular stones.

Opus reticulatum: small squared tuff blocks laid in a diamond pattern.

Opus quadratum: regularly laid courses of ashlars (masonry with finely squared stones)

Opus latericium: regularly laid courses of brick.

Opus spicatum: brick laid in a herringbone pattern (the bricks were laid in rows of chevrons).

Opus vittatum: square tuff blocks intersected by brick bands at regular and irregular distances.

Opus africanum: vertical chains of upright blocks with alternating horizontal blocks.

Opus testaceum: thick horizontal brick work.
