What is Liquid applied membranes waterproofing? Explain in details with application procedure and typical use.

Liquid applied membranes (LAMs) are thin, continuous films of polymer-based liquid that are applied to surfaces to form a waterproof barrier. They are commonly used in construction as a method of waterproofing roofs, balconies, foundations, and other structures.

The application procedure for liquid applied membranes typically involves the following steps:

1. Surface preparation: The surface to be waterproofed must be clean, dry, and free of any contaminants that could affect the adhesion of the membrane.
2. Priming: A primer is applied to the surface to improve adhesion and ensure a strong bond between the surface and the membrane.
3. Application: The liquid applied membrane is applied to the surface using a roller, brush, or spray equipment. It is important to ensure that the membrane is applied evenly and in a continuous layer, with no laps or gaps.
4. Curing: After application, the membrane must be allowed to cure and dry completely. The curing time will depend on the specific product and the conditions, but it typically takes several hours to a few days.

Typical uses of liquid applied membranes include:

1. Roof waterproofing: Liquid applied membranes can be used to waterproof flat or low-slope roofs.
2. Foundation waterproofing: LAMs can be used to waterproof basement walls and foundations to prevent water intrusion.
3. Balcony and terrace waterproofing: Liquid applied membranes can be used to waterproof balconies and terraces, protecting the structure from water damage and ensuring the durability of the surface.
4. Water tank and pond linings: LAMs can be used to line water tanks and ponds to prevent water leaks and ensure the structural integrity of the tank or pond.

Overall, liquid applied membranes are a versatile and effective method of waterproofing that offer a number of benefits, including ease of application, flexibility, and durability.
