Waterproofing Membranes
Waterproofing membranes are essential for any structure that is exposed to water, whether it be a residential property, a commercial building, or industrial plant. Waterproofing membranes are installed to create a barrier between the structure and water, serving as a protective layer that guards against water infiltration and erosion. Without the use of waterproofing membranes, the structure may become exposed to potential water and moisture damage that can cause things such as mold and mildew growth, and in extreme cases, structural failure.
Waterproofing membranes come in a variety of types and styles, each suited for different types of surfaces, including flat roofs, pitched roofs, and basement walls. The most common types of waterproofing membranes include: Self-Adhered, Fluid Applied, Sheet Applied, and Liquid Applied. Depending on the type of surface, the material that’s to be sealed, and the climate of the local area, the type of waterproofing membrane should be chosen accordingly.
Self-adhered membranes are one type of waterproofing membrane. These membranes are applied directly to the surface being treated and then a release fabric or film is placed on top of them. This type of membrane is ideal for flat roofs and basement walls, as it is easy to apply and offers excellent protection against water damage.
Another type of waterproofing membrane is the fluid applied membrane. This type of membrane consists of a liquid or semi-solid that is applied directly to the surface being treated. These membranes are particularly effective in tight spaces, as they can be applied with a brush or roller, and can also be applied to surfaces not suitable for sheet membranes. This type of membrane usually consists of a rubber or plastic-based product and offers a high level of waterproofing protection.
The third type of waterproofing membrane is the sheet applied membrane. These membranes are typically composed of plastic, rubber, or vinyl material and are applied in layers to the surface being treated. Sheet applied membranes offer excellent waterproofing protection and are often used for flat roofs and pitched roofs.
Finally, liquid applied membranes are the fourth type of waterproofing membrane. These membranes are usually made of a rubber, plastic, or vinyl material, and are applied in liquid form directly to the surface. They provide a high level of waterproofing protection and are used in areas prone to heavy rainfall or where there are large amounts of water sitting on surfaces.
No matter which type of waterproofing membrane is chosen, they should be installed in accordance with manufacturer’s instructions to ensure that they offer maximum protection. Specified jointing details must also be incorporated into the installation process, as any imperfections can lead to water seeping through the membrane and potentially damaging the structure. The application of a suitable primer before installation can help to ensure that the waterproofing membrane offers maximum protection for the surfaces being protected.
