Liquid Applied Membrane (LAM) waterproofing is a method of applying a waterproofing layer to a surface using a liquid material that hardens to form a flexible, watertight membrane. This technique is used to prevent water infiltration, damage, or leakage in various structures, including:
1. Roofs2. Walls3. Basements4. Foundations5. Tunnels6. Bridges7. Dams8. Water tanks
The process involves:
1. Preparation: Cleaning and preparing the surface2. Priming: Applying a primer (optional)3. Application: Applying the liquid membrane material4. Curing: Allowing the material to harden and form a membrane
Types of LAM materials:
1. Polyurethane-based2. Polyurea-based3. Acrylic-based4. Silicone-based5. Epoxy-based
Advantages of LAM waterproofing:
1. Flexible and adaptable to surface movements2. Seamless and continuous membrane3. Easy to apply and repair4. Resistant to weathering and UV exposure5. Can be applied to complex shapes and surfaces6. Cost-effective
LAM waterproofing is suitable for various substrates, including:
1. Concrete2. Masonry3. Steel4. Wood5. Bituminous surfaces
This method offers a reliable and durable waterproofing solution for various applications, ensuring a long-lasting and watertight seal.
