Duties
Concrete finishers place and finish concrete floors, driveways, sidewalks, curbs, bridge decks and other concrete structures.
Concrete finishers apply architectural, exposed, patterned or stamped, broomed and smooth finishes on concrete surfaces. They are skilled at repairing, waterproofing and restoring concrete surfaces.
They have the knowledge to properly use dry pack grouting and epoxy materials, and understand how to cure concrete perfectly.
In general, concrete finishers:
- Place wet concrete into the forms and spread it to a specified depth
- Level and smooth the surface, round the edges, and make joints or grooves to help control cracking on the surface
Although machines are used to trowel large areas such as warehouses and arena floors, hand trowelling is still required for hard to reach spots in corners, edges, and around pipes. The surface may be:
- Trowelled to a smooth finish
- Brushed to create a coarse, non-skid finish
- Embedded with gravel chips for an exposed aggregate finish
- Patterned or stamped to apply decorative surface
- Trowelled with a dye to create a coloured surface
Working Conditions
Concrete finishers work both outdoors and indoors, at tasks that are fast-paced and strenuous. Travel may be required to get to construction sites.
Outdoor work can be affected by adverse weather conditions. There is less work available in the winter, and summer hours are often longer than the standard 40-hour week. Overtime is sometimes required because concrete finishers cannot leave a project in the middle and return to it the next day.
There is some risk of injury from working on uneven footing and from other construction-site hazards, and the work involves considerable bending, stooping and kneeling.
