Understanding Different Types of Waterproofing Membranes

The market offers a variety of waterproofing membranes, each with its own unique properties and applications. Choosing the right one depends on factors such as the type of timber floor, the expected water exposure, and your budget. Let’s take a closer look at some of the most popular options.

• Polythene Sheets: These are thin, flexible sheets made of polyethylene plastic. They are inexpensive and easy to install, making them a popular choice for DIY projects. However, they are not as durable as other options and can be easily punctured. They are best suited for light-duty waterproofing applications, like protecting subfloors from moisture.
• Liquid Membranes: These are typically applied as a thick, rubbery coating. They are highly flexible and form a seamless barrier against water. They are ideal for complex shapes and uneven surfaces, and can be applied over existing surfaces without needing to remove them. However, they can be more expensive than other options and require a longer drying time.
• Concrete Waterproofing Membranes: These are specifically designed for use with concrete floors. They come in a variety of forms, including sheets, coatings, and slurries. They are highly durable and resistant to water penetration. However, they can be more difficult to install and may require specialized equipment.
• Bituminous Membranes: These are made from a blend of bitumen and other materials. They are highly durable and resistant to water penetration. They are often used in commercial and industrial applications, but can also be used in residential bathrooms. However, they can be difficult to install and require a skilled contractor.
