Well, the waterproof membrane you choose depends on what you’re waterproofing and how much protection you need. By definition, a waterproof membrane is a kind of physical barrier that is installed on a building (for example, pitch roof waterproofing or flat roof waterproofing) to prevent water from penetrating the waterproof membrane and creating a dry and useable interior area.Do you want to learn more?

Because there are so many options for waterproofing membrane, I am often asked, “How do I select the appropriate membrane?” Let’s start with a simple example: roofing. By its very nature, roofing necessitates a highly robust, durable, and often flexible waterproof membrane made of material that can be heat welded on site, minimising the effects of defects, which are a major concern when joining any type of waterproof membrane. A popular material for jointing any type of waterproof membrane would be rubber derivatives or compounds. EDPM roofing membrane continues to be a popular waterproof membrane option, with over 1 billion metres installed each year. Membrane roofing projects require specialised knowledge, and proper installation ensures dry interior areas. In waterproof membrane installers/contractors for low slope or flat roofing applications are regulated, and it is recommended investing in a competent roofing contractor for piece of mind and to obtain the appropriate product for the task at hand.
The specification of selecting the appropriate waterproof membrane for your application may be challenging, but one thing you can rely on is that, like a tanking membrane, it must be defect-free when tested. As a result, it’s essential to design out the risk by selecting the right waterproof membrane for the substrate. As previously stated, EDPM roof membrane applications are popular because they may be used as a flat roof membrane. When working on a project like this, you need a product that you know will not fail you down as an installer. Rubber membranes used on flat surfaces are flexible and may be welded to eliminate seams. You’ll also want to search for a product that is durable and resistant to UV rays. Some roofing membranes, particularly flat roofing membranes, may break down and fail over time as a result of exposure to sunlight, or they may simply be insufficient for the task at hand. To achieve complete adherence, products like ash felt, liquid applied roof membranes, or a single ply membrane need skilled preparation. Because this connection is so important to the waterproof membrane’s effectiveness, you should get guidance from the manufacturer to ensure that the substrate is properly prepared.
New flexible spray applied polyurethane materials can be sprayed over most substrates and are extremely forgiving due to their application method; some can be applied without joints and to a range of thicknesses. This kind of waterproof membrane has been used not just in new construction and existing roofing applications, but also as a retrofit over unsuccessful first efforts. In addition, I’ve seen this method used to protect basements and podium decks against water intrusion. Professional installers are required to apply these spray applied materials, which are more costly than a DIY option from a builders store. Request a warranty for the application from the professional installer; although this may be a more costly choice, you will have recourse if an issue arises in the future.
