The Basics Of Liquid Waterproofing Systems

Waterproofing is an essential aspect of building construction that helps to prevent water damage and ensure the longevity of the building. When it comes to roofs and balconies, waterproofing is particularly critical as these areas are exposed to the elements and are prone to water ingress. Traditional waterproofing methods, such as bitumen or PVC membranes, have been popular for many years. However, liquid waterproofing systems are increasingly gaining traction as a more flexible, durable, and cost-effective alternative.

As buildings age, it’s not uncommon for their roofs and balconies to start showing signs of wear and tear. As a result, cracks, leaks, and other forms of damage can appear, leading to serious issues if not addressed promptly. One effective solution to prevent these problems is to use a liquid waterproofing system.

What is liquid waterproofing?

Liquid waterproofing systems are coatings applied to flat or sloping roofs, balconies and other external surfaces to provide a watertight barrier. These systems typically comprise a two-component liquid resin mixed together and then applied to the surface using a brush, roller or spray. The liquid resin cures to form a seamless, flexible, and durable membrane resistant to water, UV radiation, chemicals, and mechanical damage.

There are different types of liquid waterproofing systems available. Some of the most common ones are polyurethane, polyurea, and acrylic. Each has unique features and advantages, but they all share the same primary goal: to provide a waterproof barrier for your building.

Polyurethane liquid waterproofing systems are highly flexible and durable. They can withstand a wide range of temperatures and are resistant to UV rays, chemicals, and other environmental factors. Furthermore, polyurethane systems can be used on various surfaces, including concrete, metal, and bituminous membranes. They are typically applied in two layers, with the second layer acting as a protective coating.

Benefits of liquid waterproofing

There are several benefits of using liquid waterproofing systems for roofs and balconies.

Flexibility

Liquid waterproofing systems are incredibly flexible and can adapt to the shape and contours of the surface. This makes them particularly suitable for complex shapes, such as balconies with multiple angles and curves.

Durability

Liquid waterproofing systems form a seamless and continuous membrane resistant to water and other elements. This makes them highly durable and long-lasting, with an expected lifespan of up to 25 years.

Easy to apply

Liquid waterproofing systems are easy to apply and can be installed quickly without heavy machinery or complicated equipment. This can help to reduce installation time and labour costs.

Cost-effective

Liquid waterproofing systems are generally more cost-effective than traditional waterproofing methods, such as bitumen or PVC membranes. This is because they require less material and are quicker and easier to install.
