Cold-Applied Liquid Waterproofing & Liquid Applied Membranes

This adaptability makes them ideal for both new construction and refurbishment projects, particularly for complex detailing and areas where traditional roofing materials may be challenging to install.

Cold applied liquid waterproofing systems offer a versatile and efficient solution for a wide range of waterproofing needs. Unlike traditional methods requiring heat, these systems are applied at ambient temperatures using brushes, rollers, or spray equipment. This eliminates the need for hot work, making them safer, faster, and more cost-effective to install.

Liquid waterproofing systems are available in various formulations, each with its own unique properties and applications. One of the most common and highly used formulations is Polyurethane (PU). Polyurethane systems offer excellent flexibility, durability, and chemical resistance. They are suitable for a wide range of applications, including roofs, balconies, and terraces.

Carlisle Construction Materials (CCM) is a leading manufacturer of liquid waterproofing solutions, mainly known for its ARBOFLEX® PU product. This versatile, high-performance waterproofing solution is backed by years of industry expertise.

Designed for durability, ARBOFLEX® PU provides seamless, long-lasting protection through its liquid-applied membrane, which adapts to even the most demanding project requirements. With ARBOFLEX® PU, you are well-equipped to tackle all the waterproofing challenges your projects may encounter.

Cold-applied waterproofing systems involve the application of liquid waterproofing membranes or adhesive sheets that bond to the surface, creating a protective layer. These systems rely on the chemical properties of the materials used to cure or harden at ambient temperatures, eliminating the need for external heat sources.

The application begins with thorough surface preparation, including cleaning, priming, and repairing cracks or damage. After preparing the surface, the cold materials are spread or stuck to the substrate, creating a smooth, continuous layer. This layer is a robust barrier against water, UV radiation, and other environmental factors.

Cold-applied systems are easier to use than traditional hot-applied methods. They can be applied in more types of weather and don't require flames or heat, posing fewer safety risks during installation.

Cold-applied waterproofing offers several key benefits that make it a suitable option for many projects:

Safety: Cold-applied systems do not need heat or flames, which greatly lowers the risk of fire hazards. As a result, they are a safer choice for workers and the environment.

Ease of Application: Cold-applied liquid waterproofing can be used in many weather conditions. It works well even in temperatures that would stop hot-applied systems and can be applied over existing substrates, reducing preparation time and labour costs.

Durability: These systems provide long-lasting protection against water ingress, UV radiation, and general wear and tear. They form a seamless membrane that prevents weak points where water could penetrate, enhancing the structure's longevity.

Environmentally Friendly: Cold-applied waterproofing systems usually have low volatile organic compound (VOC) emissions. This means they release fewer harmful fumes into the air during application, making them a more sustainable choice, especially for projects seeking to minimise environmental impact.

Cold-applied waterproofing is suitable for various applications thanks to its versatility and performance. Some common uses include:

• Roofing Systems: Cold-applied waterproofing provides great protection and durability for flat and sloped roofs. This is especially true in places with heavy rain or strong UV exposure.

• Balconies and Terraces: These exposed areas are vulnerable to water damage, making waterproofing critical. Cold-applied systems can withstand the elements and foot traffic, providing long-term protection.

• Basement Waterproofing: Basements are susceptible to water ingress from the surrounding soil. Cold-applied waterproofing systems help create a barrier that keeps water out, preventing flooding and structural damage.

• Car Parks and Traffic Decks: Car parks endure significant wear and tear from vehicle traffic. Cold-applied waterproofing provides a durable surface that resists water infiltration and chemical exposure.

• Green Roofs and Landscaped Areas: Green roofs are an eco-friendly way to insulate buildings and reduce urban heat islands. Cold-applied systems ensure these landscaped areas remain waterproof, preventing water damage to the underlying structure.

There are several types of cold applied waterproofing systems, each suited to different applications and needs:

• Liquid Applied Membrane: These include materials like bitumen, polyurethane, and PMMA. You apply them in liquid form, and they cure to form a seamless, durable, waterproof layer.

• Cold Adhesive Membrane: These are ready-made sheets that use adhesives to stick to surfaces, creating a fast and effective waterproof barrier.

Multi-Layer Systems with Reinforcement: We often use multi-layer systems for places with heavy traffic or extra protection. These systems are reinforced with fabric or mesh to enhance durability and performance.

Q: How long does a liquid applied membrane last
A: The lifespan of a liquid applied membrane depends on factors such as the quality of the product, the environment, and the level of maintenance. Generally, these systems last between 15-25 years, with proper application and care.

Q: Can a liquid applied membrane be used in extreme weather conditions?
A: Yes, a liquid applied membrane is designed to withstand a wide range of weather conditions. They are especially useful in areas with heavy rainfall, extreme UV exposure, and temperature fluctuations.

Q: Is it possible to apply a liquid membrane over an existing waterproofing system?
A: Yes, a liquid applied membrane can be applied over existing systems as long as the surface is in good condition. In fact, this is often done during refurbishment projects to extend the lifespan of the structure.

Q: Is a liquid applied membrane environmentally friendly?
A: Yes, liquid applied membranes are typically low in volatile organic compounds (VOCs) and produce fewer harmful emissions compared to other methods. This makes them a more eco-friendly option for modern construction projects.
