The Different Types of Waterproofing Membranes you Should Consider for Your Property

Waterproofing membranes are an important part of waterproofing, which is the process of preventing water from entering or exiting a building. There are many different types of membranes that you can use for your project, and knowing which one is right for you can help ensure that your waterproofing project is successful. In this article we will discuss the different types of membranes available and how they work:

What are waterproofing membranes?

Waterproofing membranes are materials that help to protect your roof from water damage. They are flexible and durable and can be installed on flat roofs, sloped roofs, or domes.

Sheet-based Membranes

Sheet-based membranes are made of a thin sheet of plastic. They are used in flat roofs and walls but are not suitable for pitched roofs. Sheet-based membranes can be applied to flat roofs, walls, and floors.

They are used in the construction industry to waterproof building materials such as concrete slabs. In the past, they were made from rubberized asphalt products which have now been replaced with polyvinyl chloride (PVC).

Polymer-modified bitumen membranes

Polymer-modified bitumen membranes are a type of sheet-based membrane that is flexible and easy to install. They can be used in a variety of applications, such as waterproofing roofs and walls. These membranes are durable, long-lasting, and resistant to water, chemicals, UV rays, and other harsh weather conditions.

Building Paper

Building paper is a thin sheet of material used to protect the interior of a building from water damage. Building paper comes in various forms, including asphalt-impregnated kraft paper and polyethylene or polypropylene. Building paper is made from various materials that are coated with an asphalt compound to keep water out. It’s typically used as an underlayment for roofs and walls.

Building Paper Pros:

  • Cheap option
  • Works well in wet climates

Self-adhesive Membranes

Self-adhesive membranes are the most commonly used type of membrane. They can be installed quickly and easily, and they can be placed on a wide variety of substrates. If you’re looking to waterproof your property, but don’t want to pay for custom installation services or hire an expert, self-adhesive membranes are a great option.

Because they’re so simple to use and install, self-adhesive membranes tend to be very cost-effective as well. They’re also waterproof and flexible—a combination that makes them weatherproof while still remaining easy on your wallet!

Fluid-applied Waterproofing Membranes

  • Fluid-applied membranes are applied using spray equipment. They can be used in areas where there is a lot of movement, such as on roofs and around windows.
  • Fluid-applied membranes are not suitable for use on flat roofs or other surfaces where movement is minimal, such as in basements or crawlspaces.

Elastomeric coating

Elastomeric coatings are a type of membrane that is applied directly to the surface of the substrate. These membranes are used to waterproof concrete and masonry surfaces and can be used on new or existing concrete or masonry surfaces. The elastomeric coating creates an air space between the substrate and waterproofing layer. It also acts as a barrier between different levels in a structure when installed below ground level.


The best waterproofing membrane for your home or property will depend on the needs of your project. If you need to waterproof a flat roof, for example, then a sheet-based membrane is probably your best option. On the other hand, if you have an exposed wall that needs waterproofing then a self-adhesive membrane might be better suited to this situation.
