Gharshoppe Quality Inspector Interview Questions and Answers

Waterproofing types include membranes, coatings, and sealants, chosen based on application, environment, and material compatibility.

• 1. Membrane Waterproofing: Used for roofs and foundations; examples include bituminous and PVC membranes.

• 2. Liquid Coating: Applied as a liquid that cures to form a waterproof layer; examples are polyurethane and epoxy coatings.

• 3. Cementitious Waterproofing: Ideal for water tanks and basem...read more

FE550 and FE550D are different grades of steel with varying properties and testing standards.

• FE550 is a grade of structural steel, while FE550D is a ductile variant with enhanced toughness.

• FE550 is typically used in construction, while FE550D is preferred in seismic zones due to its ductility.

• Common tests for FE550 include tensile strength, yield strength, and elongation tests.

• FE550D undergoes additional tests for impa

Using higher grade materials for early de-shuttering can enhance structural integrity but may not always be necessary.

• Higher grade materials can provide better strength and durability, allowing for earlier de-shuttering.

• For example, using high-strength concrete can reduce curing time and allow for earlier removal of formwork.

• However, this may increase costs and may not be justified if standard materials meet project re...read more

Moisture levels must be controlled before applying polyurethane coatings to ensure adhesion and durability.

• Ideal moisture content is typically below 15% for wood substrates.

• Excess moisture can lead to poor adhesion, causing the coating to peel or blister.

• For concrete surfaces, moisture vapor transmission should be less than 3 lbs/1000 sq ft/24 hrs.

• Using a moisture meter can help assess the substrate's moisture levels b...read more

Work procedure involves detailed steps to complete a task efficiently and effectively.

• Identify the task to be completed

• Break down the task into smaller steps

• Assign responsibilities to team members

• Set deadlines for each step

• Monitor progress and make adjustments as needed

Waterproofing methodology involves applying materials to prevent water penetration, while gypsum starting process involves mixing gypsum with water to create a paste.

• Waterproofing methodology includes surface preparation, application of waterproofing materials like membranes or coatings, and proper curing.

• Examples of waterproofing materials include bituminous coatings, cementitious coatings, and liquid-applied membrane...read more
