L&T Construction Assistant Civil Engineering Manager Interview Questions, Process, and Tips

The thickness of a tile can vary depending on the type and size of the tile being used.

• Tile thickness typically ranges from 1/4 inch to 3/4 inch.

• Larger tiles may have a thicker thickness to support their weight.

• Thin tiles are often used for wall applications, while thicker tiles are used for flooring.

• Porcelain tiles are usually thicker than ceramic tiles.

The thickness of marble can vary depending on the type and purpose, but it is typically between 3/4 inch to 1 1/4 inches.

• Marble thickness can range from 3/4 inch to 1 1/4 inches

• Thicker marble is often used for countertops and flooring

• Thinner marble may be used for wall cladding or decorative purposes

The process of flooring involves selecting the appropriate materials, preparing the subfloor, laying the flooring material, and finishing with trim.

• Selecting the appropriate flooring material based on the location and usage (e.g. hardwood, laminate, tile, carpet)

• Preparing the subfloor by ensuring it is clean, level, and dry

• Laying the flooring material according to manufacturer's instructions, starting from the center o...read more

Types of tiles include ceramic, porcelain, glass, and natural stone. Cement ratio in tile installation varies depending on the type of tile and substrate.

• Types of tiles: ceramic, porcelain, glass, natural stone

• Cement ratio varies based on tile type and substrate

• Ceramic tiles typically require a 1:4 cement to water ratio for installation

• Porcelain tiles may need a 1:3 cement to water ratio for proper adhesion

Flooring process involves selecting materials, preparing the subfloor, installing the flooring, and finishing with trim.

• Selecting appropriate flooring material based on budget, durability, and aesthetics (e.g. hardwood, laminate, tile, carpet)

The cement ratio for flooring depends on the type of flooring and the strength required.

• The typical cement ratio for standard concrete flooring is 1:2:4 (cement:sand:aggregate)

• For high strength flooring, the ratio can be increased to 1:1.5:3

• For decorative or polished concrete flooring, a lower water-cement ratio is used to achieve a smoother finish
