Waterproofing is one of the fundamental requirements of all buildings. This is typically achieved using a waterproofing membrane. This membrane is a continuous, thin-layer material laid over your surface, which allows no water to pass through; therefore, keeping your substrate dry.
Waterproofing tiling and other waterproofing products are the common options used to protect surfaces in Sydney. Durability and the bonding ability of your membrane are among the crucial elements you should consider when buying your waterproofing membrane. Here are the other key features that should influence your decision:
Elongation refers to the ability of your membrane to stretch when pulled and is necessary to accommodate cracks, which may develop in your building over time. It is denoted in percentages and is an essential element in buildings that are prone to moving, such as high-rise and steel buildings. A membrane elongation of 200% is the ideal for most buildings. A 200% elongation means the membrane can stretch up to two times its length.
Even the best waterproofing can sometimes allow water into the surface. If this happens in a non-breathable membrane, the water will be trapped inside your structure and might damage your substrate. Breathable membranes release water that might get stuck under your membrane to the atmosphere as water vapor.
This refers to your waterproofing membrane’s ability to resist wear and tear. Abrasion resistance is a crucial element during construction, as workers walk on the surface and might drop sharp objects that can damage the membrane. Soft membranes with low abrasion resistance are prone to damage at this time, causing them to leak.
UV stability is an essential waterproofing property for membranes used in areas exposed to direct sunlight. Membranes that are not UV stable will typically degrade over time. The curing time of your waterproofing membrane is also critical, as it will impact your project’s timeline.
