Mastic asphalt is generally used for A. Damp proof course B. Water proof layer C. Partition walls D. Both (A) and (B)

Mastic asphalt is a type of asphalt that is made by heating asphalt cement and then adding a filler, such as sand or limestone. It is a thick, sticky material that is used for a variety of purposes, including:

• Damp proofing: Mastic asphalt can be used to create a waterproof barrier between the ground and a building’s foundation. This helps to prevent moisture from seeping into the building and causing damage.
• Waterproofing: Mastic asphalt can also be used to create a waterproof barrier on roofs and other surfaces. This helps to protect the surface from water damage.
• Paving: Mastic asphalt can be used to create a durable and long-lasting pavement. It is often used in parking lots and driveways.
• Roofing: Mastic asphalt can be used to create a waterproof roof. It is often used on flat roofs or roofs that are exposed to a lot of moisture.
• Siding: Mastic asphalt can be used to create a watertight seal around windows and doors. It is often used on homes that are located in areas with a lot of rain or snow.

In conclusion, mastic asphalt is a versatile material that can be used for a variety of purposes. It is a good choice for damp proofing, waterproofing, paving, roofing, and siding.

Here is a brief explanation of each option:

• Option A: Damp proof course (DPC) is a layer of material that is used to prevent moisture from seeping into a building. Mastic asphalt can be used to create a DPC.
• Option B: Water proof layer: Mastic asphalt can be used to create a waterproof barrier on roofs and other surfaces.
• Option C: Partition walls: Mastic asphalt is not typically used for partition walls.
• Option D: Both (A) and (B): Mastic asphalt can be used for both damp proofing and waterproofing.
