A liquid waterproofing membrane is a coating that is applied in liquid form and then dries to create a protective layer. It can be applied using a brush, roller, or spray. On the other hand, a sheet-type waterproofing membrane is a pre-manufactured material made of rubber, PVC, or bitumen. It comes in large rolls or sheets and is usually installed by overlapping the sheets and adhering them to the surface using adhesives or heat.
When it comes to installation, liquid waterproofing membranes are generally easier to apply because they can be molded and shaped to fit different surfaces and contours. They can also be applied to both horizontal and vertical surfaces without the need for seams or joints. Sheet-type membranes, however, require precise measurements and cutting to properly fit the surface. They also require more labor and time to install due to the need for overlapping and sealing the joints.
In terms of flexibility, liquid membranes have better flexibility as they can conform to irregular surfaces and movements without cracking or tearing. Sheet-type membranes, while somewhat flexible, may not be able to adapt as well to surface movements or changes in temperature.
Another difference is durability and lifespan. Sheet-type membranes are typically thicker and more robust, offering a longer lifespan and better resistance to punctures and mechanical damage. Liquid membranes, although effective for waterproofing, may not be as durable or long-lasting, particularly in high-traffic areas or areas prone to damage.
When it comes to cost, liquid waterproofing membranes are generally more cost-effective compared to sheet-type membranes. They require less labor and materials for installation, making them a more budget-friendly option. However, it's important to consider the specific requirements and conditions of the project to determine the most suitable type of waterproofing membrane.
Overall, the choice between a liquid and sheet-type waterproofing membrane depends on various factors such as the nature of the project, surface conditions, required flexibility and durability, and budget constraints.

The main difference between a liquid and sheet-type waterproofing membrane is their physical form and application method. A liquid membrane is typically applied as a liquid coating that dries to form a seamless, flexible, and durable waterproofing layer. It is often used for irregular or hard-to-reach surfaces and can be easily applied using a brush, roller, or spray. On the other hand, a sheet-type membrane is a pre-made sheet or roll that is applied to a surface using adhesive or heat welding. It provides a continuous, barrier-like waterproofing layer and is commonly used for large, flat surfaces. Overall, the choice between a liquid and sheet-type membrane depends on the specific project requirements, surface characteristics, and application preferences.
