Dampproof Material

Description

Damp-proofing is a method used to prevent moisture from entering a building. Here are some common materials used for damp-proofing

1. Hot Bitumen: A flexible material applied on concrete or mortar beds with a minimum thickness of 3 mm.
2. Mastic Asphalt: A semi-rigid, durable, and impervious material that forms an excellent damp-proof layer.
3. Bituminous Felts: Flexible and easy to lay, these felts are available in rolls and are laid on a layer of cement mortar.
4. Metal Sheets: Sheets of lead, copper, and aluminum can be used as damp-proof membranes. Lead sheets are particularly flexible and resistant to sliding action.
5. Plastic Sheets: These are also used as damp-proof membranes and are laid on concrete or mortar beds.
