Top 10 Questions for Screedman/Laborer Interview

1. How do you ensure the accuracy and consistency of the concrete screed?

• I use precision tools such as laser levels and screed rails to level and smooth the concrete.
• I check the alignment regularly throughout the process to maintain accuracy.
• I collaborate with the team to ensure consistency in techniques and materials.

2. Describe your approach to managing slope and drainage when screeding concrete.

Slope Management

• I use slope gauges or laser levels to determine the desired slope.
• I adjust the pitch of the screed rails accordingly.
• I screed the concrete in gradual sections to maintain the slope.

Drainage

• I consider the topography and drainage patterns of the site.
• I create channels or slopes in the concrete to facilitate water drainage.
• I ensure proper slope direction to prevent pooling or flooding.

3. What techniques do you use to minimize shrinkage cracks in concrete?

• I use low-shrinkage concrete mixtures.
• I apply curing compounds or plastic sheeting to retain moisture.
• I cut control joints at appropriate intervals to relieve stress.
• I minimize exposure to excessive wind and heat during curing.

4. How do you inspect and prepare a concrete surface before placing new concrete?

• I inspect for existing cracks, defects, or contaminants.
• I clean the surface by pressure washing or sandblasting.
• I roughen the surface with diamond grinders to enhance bonding.
• I apply a bonding agent or primer to promote adhesion.

5. What are some common challenges you have encountered as a Screedman/Laborer and how did you overcome them?

• Uneven or sloping surfaces: I used precision equipment and adjusted screed rails to create a level surface.
• Excessive moisture: I adjusted the concrete mix and applied moisture barriers to prevent weakening.
• Harsh weather conditions: I used protective measures such as tarps and heaters to maintain proper temperature and curing.

6. How do you stay up-to-date on the latest concrete technologies and best practices?

• I attend industry workshops and conferences.
• I read trade publications and research reports.
• I consult with manufacturers and experts in the field.

7. Describe your experience in using power trowels and related equipment.

• I am proficient in operating power trowels of various sizes and types.
• I know how to adjust blades and speeds for different concrete finishes.
• I maintain and repair equipment regularly to ensure optimal performance.

8. How do you ensure safety while working with concrete and heavy equipment?

• I wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and boots.
• I follow established safety procedures and guidelines.
• I maintain a clean and organized work area.
• I am aware of potential hazards and take necessary precautions.

9. What is your understanding of concrete admixtures and their effects on concrete properties?

• Accelerators: Increase setting and hardening time.
• Retarders: Extend setting time, allowing for more working time.
• Plasticizers: Improve workability and reduce water content.
• Air-entraining agents: Introduce air bubbles to enhance durability and freeze-thaw resistance.

10. Describe your experience in performing concrete finishing tasks such as texturing, stamping, and staining.

• Texturing: I use brooms, brushes, or stamping tools to create different surface textures.
• Stamping: I use rubber or polyurethane stamps to imprint patterns into fresh concrete.
• Staining: I apply stains or dyes to enhance the color or appearance of concrete.

Screedmen/Laborers are responsible for a variety of tasks related to the preparation, placement, and finishing of concrete surfaces. Their primary job duties include:

1. Preparing the Subgrade

Before concrete can be placed, the subgrade must be prepared to ensure proper drainage and support. Screedmen/Laborers perform this task by removing any debris, leveling the surface, and compacting the soil or gravel.

2. Setting Up Forms and Reinforcing Bars

Once the subgrade is prepared, forms are set up to create the desired shape and size of the concrete surface. Screedmen/Laborers also install reinforcing bars to strengthen the concrete and prevent cracking.

3. Placing and Leveling Concrete

Concrete is typically delivered to the job site in a ready-mix truck. Screedmen/Laborers use shovels and rakes to place and level the concrete within the forms.

4. Screeding and Finishing

Once the concrete has been placed, Screedmen/Laborers use a screed to level and smooth the surface. They may also use a bull float or trowel to create a desired texture or finish.

5. Curing and Protection

After the concrete has been finished, it must be cured to allow it to gain strength and hardness. Screedmen/Laborers cover the concrete with plastic sheets or burlap and keep it moist for several days.
