Applications of Membrane Waterproofing in Modern Construction

Membrane waterproofing is essential in areas prone to water ingress, such as basements, terraces, and balconies. By creating a protective barrier, it prevents moisture from seeping into the building’s structure, safeguarding against potential water damage. Licata’s waterproof membranes are highly versatile and effective for both residential and commercial projects.

These systems are particularly beneficial in protecting foundation walls and concrete surfaces exposed to high levels of moisture. Whether it’s a new build or a renovation, Licata’s external waterproofing solutions ensure long-lasting protection for various types of structures.

Protecting Against Hydrostatic Pressure with Advanced Membranes

Water pressure from surrounding soil, especially in basements, can lead to significant structural issues if left unchecked. Licata provides external waterproofing systems designed to combat hydrostatic pressure, reducing the risk of water ingress. These systems act as a reliable barrier, keeping your building’s foundation safe.

Secondary waterproofing products, such as drainage membranes, can be installed alongside primary systems to further protect structures from damage caused by accumulated moisture. These additional layers of protection help ensure the longevity of the waterproofing system.

Choosing the Right Waterproofing Membrane for Your Project

Selecting the right waterproof membrane depends on the specific needs of the project. Licata offers a range of waterproofing products, including liquid-applied membranes and sheet membranes, which are highly flexible and suitable for various substrates. These options allow for seamless application and durable protection.

For areas exposed to heavy moisture, like basements and wet rooms, Licata’s waterproofing systems provide effective solutions. Their team of experts can guide you in choosing the ideal product for your construction needs, ensuring optimal performance and longevity.

Innovations in Liquid-Applied Waterproofing Technology

Licata’s liquid-applied waterproof membranes provide a seamless barrier that protects structures from water ingress. These waterproofing systems are easy to apply and adhere well to a variety of surfaces, making them a practical choice for many construction projects.

Their highly flexible properties allow them to adapt to minor cracks or shifts in the substrate, ensuring long-lasting protection. With Licata’s range of waterproofing products, builders can confidently protect concrete foundations and other vulnerable structures from moisture and water damage.

Frequently Asked Questions (FAQs)

1. What is the best membrane for waterproofing?

The best waterproofing membrane is one that offers flexibility, durability, and long-term protection against water ingress. Licata’s Licalastic 150 PU system ticks all the boxes, providing a seamless, cold-applied solution that works across various surfaces, including concrete, balconies, and basement walls.

Its membrane waterproofing system forms a flexible barrier that resists cracking, adapts to the substrate, and protects the structure underneath. Supplied in multiple variants, it’s suitable for residential and commercial buildings that need reliable waterproofing for exposed or ground-level areas.

2. How long does membrane waterproofing last?

Membrane waterproofing can last 10 to 20 years or more when applied correctly and maintained properly. Licata’s systems are designed for long-term performance, and projects carried out by approved applicators come with warranties of up to 10 years.

The durable nature of polyurethane-based waterproof membranes ensures that they protect ground structures, balconies, and basement floors from continuous water exposure. With the right drainage and surface preparation, they create a watertight barrier that stays effective over time.

3. Is membrane waterproofing better than cementitious waterproofing?

Membrane waterproofing is often more flexible and adaptable than cementitious methods, especially for surfaces that are prone to movement. Licata’s liquid-applied membranes can bridge small cracks and seal joints effectively, offering greater resilience in basements and terraces.

Cement-based systems can become brittle over time, while polyurethane membranes maintain elasticity and form a long-lasting barrier against water. Whether applied internally or externally, Licata’s membranes are suitable for various substrates and provide superior protection for modern structures.

4. Does membrane waterproofing work in extreme weather?

Yes, Licata’s waterproof membranes are designed to perform in all kinds of weather, from hot summers to freezing winters. Once cured, they remain elastic and prevent water ingress, even on surfaces that are exposed to direct sunlight or heavy rain.

This makes them ideal for balconies, terraces, and ground-level areas where waterproofing needs to be both tough and reliable. The Licalastic 150 PU system can be applied with a roller or brush and cures to form a waterproof layer that protects the structure beneath, even in challenging environments.

5. Can you tile over a waterproof membrane?

Yes, you can tile directly over Licalastic 150 PU once the membrane has fully cured. This makes it a suitable choice for wet rooms, balconies, and other areas where tiled finishes are required after waterproofing.

The membrane creates a strong base that protects the concrete or substrate below while allowing for secure tile adhesion. Its seamless finish ensures no weak points are left behind, so your structure remains safe from future water ingress or damage.
