b. Type • Smooth Surface

• Rough Surface

During manufacturing, the side of

the wall facing the conveyor belt

will produce smooth surfaces,

while the side exposed to the air

will produce rougher surfaces.

c. Other

Considerations

• Smooth-faced surfaces are

marked by an arrow on the shop

drawing

• Smooth-faced surfaces are often

specified to face the external, so

as to decrease the amount of

finishing works to be done

(hence decreasing scaffolding

works)
