Waterproofing a Terrace with Liquid Rubber

Only when a patio— including its joints —has been properly sealed can the building structure be reliably protected from damage caused by moisture penetration. Anyone looking to seal patio joints needs a solution that is flexible, weather-resistant, and provides long-lasting protection. However, due to their exposed location, patios are subject to the effects of wind, weather, and temperature fluctuations year-round. Water intrusion causes mold and weakens the material of the patio surface. Only a permanently sealed patio can reliably withstand these effects. The patio waterproofing must also be able to withstand localized mechanical stress, such as from moving furniture and planters or from use by residents.

When it comes to waterproofing a terrace, Triflex products have proven their worth. With our liquid-applied systems based on polymethyl methacrylate resin (PMMA), we offer an efficient way to permanently waterproof terraces and protect them from moisture and dampness. At the same time, they offer a wide range of color options. Our systems are fully reinforced with a nonwoven fabric, ensuring that the terrace waterproofing remains elastic and can withstand even movements within the structure. Triflex systems are ideal not only for waterproofing the surface but also for specifically sealing terrace joints, even with complex geometries and connection details. Waterproofing a terrace means providing lasting protection for the building structure. Specifically, Triflex solutions offer the following properties:

Whether it’s a new construction or a renovation, having your patio waterproofed ensures that the building’s structure is preserved for many years to come and results in a significant increase in the property’s value. As a rule, the patio can be waterproofed without demolition and, consequently, without generating dust and dirt. No sealing tape or additional work is required, which saves both time and money. The liquid polymer is applied directly to the existing flooring on a variety of substrates. This is easily achievable thanks to the system’s thin profile and the excellent adhesion properties of PMMA.

When it comes to waterproofing a terrace, Triflex’s PMMA solutions come into play. The decision regarding which system best suits the specific conditions is typically made by the applicators and our Triflex application engineers in collaboration with the building owner. Only then can the terrace be waterproofed in a way that leaves everyone involved in the project satisfied. Many of our solutions have one thing in common: the integrated, geotextile-reinforced detail waterproofing system Triflex ProDetail. This was developed specifically for connections to building components, such as at transition areas to doors or floor drains. It allows the deck to be reliably waterproofed—including the deck joints. The combination of geotextile and liquid polymer ensures a durable waterproofing, even when the structure moves.

Functional and customizable—our Triflex system solutions combine both qualities to waterproof a terrace while enhancing its appearance. In addressing the challenge of permanently waterproofing a patio, our PMMA solutions offer the option of applying a sealant to the surface. This enhances the appearance of the outdoor space and gives it a fresh, glossy finish. To this end, we at Triflex offer over 70 different surface textures and color options. With Triflex Chips Design, a decorative aggregate is added to the liquid resin, which—in combination with a quartz sand finish—gives the floor slip-resistant properties. Triflex Colour Design opens up a creative color palette, ranging from gray-blue to red-orange to cream-beige. Waterproofing the patio and then creating a natural-looking surface—we make this possible with Triflex Stone Design. The addition of marble gravel or granite chippings also gives the substrate excellent drainage properties. Triflex Creative Design rounds out the range of surface options for patio waterproofing. Design films are applied to the floor, allowing for the imitation of various shapes, patterns, and ornaments. In this way, our PMMA solutions offer a wide range of possibilities for waterproofing the terrace while also creating a visually appealing finish.
