What Material Is A Waterproof Membrane?


Several materials can be used to cover your roof or other structure. These include PVC, bituminous membrane, liquid membrane, and fiberglass. Learn the properties of each and choose the right combo roofing system in UAE that is right for your project. A waterproof membrane can help prevent water from soaking into your building and will prevent the growth of mold and mildew.


A fully synthetic adhesive waterproof membrane, PVC waterproof membranes protect against moisture, tensile, and shear forces. They are highly durable and suitable for agricultural installations, including non-permanent sheds. They can be installed in wet weather and are frost resistant. These membranes are made of plasticized PVC reinforced with polyester and have a fleece finish on the lower surface.

Bituminous membrane:

Bituminous membranes are high-performance thick solutions that have good mechanical strength and good vapor barriers. They are also highly resistant to fire and have excellent adhesion properties in low temperatures. They are commonly used for waterproofing flat roofs, podium decks, retaining walls, and basements.

Polymer-bitumen membranes are also available. While polymer-bitumen membranes can be applied to irregular surfaces, the bituminous membrane is most effective when applied over unobstructed surfaces. Its ability to stretch up to 280% increases its flexibility, making it less likely to crack as a building moves. Bituminous membranes are available in different layers and are often covered with sand to provide additional protection.

Liquid membrane:

Liquid waterproof membranes are versatile and effective solutions to a variety of waterproofing problems. They offer a seamless, monolithic fluid membrane that is easy to apply. Applied properly, liquid waterproof membranes form an elastic waterproof seal. Because of their flexibility, liquid waterproof membranes can be applied with a roller and can adhere to most surfaces.


Fiberglass is a waterproof membrane material that can prevent the ingress of water from roofs and walls. It is composed of fiberglass yarn, which makes it ideal for use with cold application cement. It is also flexible and conforms to all bends and contours, making it ideal for general roofing maintenance.

Fiberglass is also resistant to alkali and acid, making it an excellent choice for roofs. Its elasticity makes it easy to cut and install and it is durable enough to last for up to 50 years. In addition, fiberglass is easy to install, even on sharp corners.
