HomeDifferent Types of Wall Waterproofing Explained: A Complete Guide
Apr 10, 2023
The walls of your home do not just define its look, they set the tone for your home’s ambience. Whether it is the interior or the exterior, walls need the right care to preserve their beauty and integrity. A fresh coat of paint and stylish interiors are essential for enhancing your space. But there’s one often-overlooked step in maintaining your walls—waterproofing.
Water infiltration can lead to peeling paint, mould growth, and cracks. These issues affect the aesthetics and the structural health of your home. That is why investing in proper wall waterproofing is essential to protect your property from water damage. But with so many waterproofing methods available, how do you choose the right one for your walls?
-
Bituminous Waterproofing
Bituminous waterproofing includes the use of bitumen-based materials to keep water out. Think of it as the tough shield your walls need, especially when it comes to foundations and underground areas. By mixing in polymers and fibre, it forms a durable, vapour-proof coating that stands up to the test of time.
-
Bituminous Membrane
If you are dealing with low-sloped roofs or foundations, bituminous membranes are your go-to. These come in two main types: torch-on membranes or self-adhesive sheets. They are built to take on harsh weather and even feature mineral aggregates for extra durability. Whether you are protecting large surfaces or flat roofs prone to water pooling, this option is ideal if you are looking for a weatherproof, low-maintenance solution.
-
Polyurethane Liquid Membranes
For something a bit more high-tech, polyurethane liquid membranes offer top-notch waterproofing. This flexible coating can be used on a wide variety of surfaces, from flat roofs to terraces, balconies, and other exposed areas. Its superior flexibility and weather resistance make it a top performer in areas that face extreme weather.
-
Acrylic Waterproofing
When it comes to exterior wall waterproofing, especially those dealing with cracks or heavy rain, acrylic is the way to go. This method uses a fibre-reinforced, elastomeric coating that is flexible enough to bridge cracks and create a solid water-resistant membrane. It is quick, easy to apply, and suitable for safeguarding your walls. If you want something that will last and keep your home’s exterior looking fresh, acrylic is a great choice for exterior waterproofing.
- Integral Waterproofing
For new builds or major renovations, integral waterproofing is the right choice. It is added directly into the cement mix, meaning the waterproofing protection is built right into the structure. This makes it a great solution for foundations and walls that need permanent, no-hassle protection.
Choosing the Right Waterproofing for Your Walls
Now that you are familiar with the different types of waterproofing, how do you choose the best one for your home? Here are a few factors to consider:
- Where is the moisture coming from? For external threats like rain, prioritise flexible and weather-resistant solutions like liquid membranes or acrylic coatings.
- What is your budget? Cementitious waterproofing is suitable for budget-conscious homeowners, while polyurethane and bituminous options cater to those seeking durability.
- Are you renovating or building new? Existing walls may require coatings or membranes, while integral waterproofing is tailored for new construction.
