Top 10 Questions for Screed Person Interview

1. What are the different types of screeds and their uses?

There are various types of screeds, each with a specific purpose:

• Hand screed: A long, flat tool used for striking off and leveling fresh concrete.
• Bull float: A wider, rectangular tool used to smooth and level larger concrete surfaces.
• Laser screed: An advanced machine that uses a rotating laser beam to level and compact concrete automatically.
• Vibrating screed: A tool that uses vibrations to consolidate and remove air bubbles from concrete.
• Trowel screed: Used to create polished or textured surfaces on concrete floors.

2. Explain the process of screeding concrete.

Preparation:

• Prepare the subgrade to be level and properly compacted.
• Set up formwork to contain the concrete.

Screeding:

• Pour fresh concrete into the formwork.
• Use a hand screed or bull float to level the concrete.
• Remove excess concrete and compact it.

Finishing:

• Use a trowel screed to smooth the surface.
• Cure the concrete properly to prevent cracking.

3. What factors affect the quality of screed work?

• Proper preparation of the subgrade and formwork.
• Use of appropriate screeding tools and techniques.
• Concrete mix design and placement.
• Environmental conditions (e.g., temperature, humidity).
• Skill and experience of the screed person.

4. How do you ensure that the screed is level and within specifications?

• Use a level or laser screed to check the flatness.
• Measure the thickness of the screed at regular intervals.
• Compare the results to the job specifications.
• Make adjustments as needed to achieve the desired level and thickness.

5. What is the importance of curing concrete properly after screeding?

• Prevents moisture loss, which can lead to shrinkage and cracking.
• Strengthens the concrete by allowing it to continue hydrating.
• Improves the durability and resistance to wear.

6. Describe the different types of concrete finishes and how they are achieved.

• Troweled finish: Using a trowel to create a smooth, dense surface.
• Broom finish: Sweeping a broom over the surface while it is still wet to create grooves.
• Exposed aggregate finish: Washing away the top layer of concrete to reveal the aggregate.
• Stamped concrete finish: Impressing a pattern into the concrete using a mold.

7. What are the common problems encountered in screed work and how do you resolve them?

• Cracks: Can be caused by improper curing, shrinkage, or inadequate reinforcement.
• Uneven surface: Caused by poor leveling during screeding or improper use of tools.
• Holes or voids: Caused by air bubbles or improper consolidation.
• Spalling: Deterioration of the concrete surface due to freeze-thaw cycles or exposure to deicing agents.

8. How do you handle working with different types of concrete mixtures?

• Familiarize myself with the mix design and its properties.
• Adjust screeding techniques as needed to accommodate the specific characteristics of the mix.
• Test the mix on a small area to ensure proper workability and setting time.

9. How do you work safely on a screeding project?

• Wear proper personal protective equipment (PPE).
• Handle heavy equipment carefully.
• Be aware of potential hazards (e.g., tripping, electrical wires).
• Follow established safety procedures on the job site.

10. What is your experience with using laser screeds?

• Describe the benefits and challenges of using laser screeds.
• Discuss your experience with setting up, operating, and maintaining laser screeds.
• Explain how you use laser screeds to achieve precise leveling and compaction.

Screed Persons are responsible for the proper installation and finishing of concrete surfaces. They use specialized tools and techniques to ensure that concrete is smooth, level, and free of defects.

1. Preparing the Work Area

Screed Persons begin by preparing the work area. This includes clearing the area of debris, leveling the ground, and setting up forms for the concrete.

2. Installing the Concrete

Once the work area is prepared, Screed Persons install the concrete. They use a variety of tools to spread, level, and compact the concrete.

3. Finishing the Concrete

After the concrete has been installed, Screed Persons finish it using a variety of hand tools and machines. This includes screeding the concrete to remove any high spots, floating the concrete to remove any bubbles, and troweling the concrete to smooth and compact it.

4. Inspecting the Finished Product

Once the concrete has been finished, Screed Persons inspect it to ensure that it meets the required specifications. They also make any necessary repairs or adjustments.

To prepare for an interview for a Screed Person position, candidates should do the following:

1. Research the Company

Candidates should research the company they are interviewing with to learn about its history, culture, and values. This will help them to determine if the company is a good fit for them.

2. Prepare for Common Interview Questions

Interviewers often ask the same questions when interviewing for a Screed Person position. Candidates should prepare for these questions by practicing their answers and thinking about examples from their own experience.

3. Develop a Strong Portfolio

Candidates should develop a portfolio that showcases their skills and experience in screeding. This could include photos of their work, letters of recommendation, and other relevant materials.

Here are some examples of common interview questions for Screed Person positions:

• Tell me about your experience in screeding concrete.
• What are the different types of screeds and when do you use each type?
• How do you ensure that the concrete is level and smooth?
• What are the most common problems you encounter when screeding concrete and how do you solve them?
• What are your safety procedures when working with concrete?
