Waterproofing for built-in showers

The ultimate solution against leaks in walk-in showers

Walk-in showers offer great design freedom and customisation, but their biggest challenge is waterproofing. Without proper protection, leaks can cause serious structural damage, persistent moisture, and even health issues related to mould and fungi. At Revestech, we offer advanced solutions to waterproof walk-in showers, ensuring total protection against water and vapour, while guaranteeing durability and wellbeing in your home.

Our waterproofing membranes such as ECODRY50 and DRY50 are specifically designed for walk-in showers, providing an impermeable barrier that protects both the floor and walls from any leaks.

These membranes are easy to install, even in irregular or customised walk-in showers, and do not require complicated construction work or the removal of existing flooring. This makes them the best option for new build and renovation projects.

Why is it essential to waterproof walk-in showers?

Contrary to popular belief, ceramic tiles and their joints are not completely waterproof. The joints, due to their porous nature, can absorb water over time, damaging the substrate, causing dampness and affecting the materials that make up the shower structure. Over time, this can lead to leaks, foundation problems, damage to neighbouring properties, and the growth of mould and fungi.

The key to preventing these issues is to use a waterproof membrane beneath the floor and wall tiles. Revestech offers solutions that ensure water cannot penetrate or affect the underlying structure, creating a completely sealed and protected shower.

The best waterproofing solutions for walk-in showers

En el mercado existen varias opciones para impermeabilizar duchas de obra, pero no todas garantizan una protección duradera y de calidad. En Revestech, nos centramos en dos soluciones principales que se adaptan a las necesidades de nuestros clientes:

1. Revestech waterproofing membranes

Our waterproofing membranes are the best option for effective and long-lasting waterproofing. Made from high-strength plastic compounds, these membranes easily adhere to the surface of the floor or walls, ensuring that no water or vapour penetrates the lower layers.

They are easy to install and are designed for walk-in showers of any size or shape, ensuring quick installation without the need for rubble removal. They are perfect for both new builds and renovation projects.

    • Hassle-free installation: They adhere directly to the surface without the need to remove the existing flooring.
    • Total protection against water and vapour: Ideal for high-use showers and bathrooms with high moisture exposure.
    • Mould and fungi prevention: Thanks to their waterproof barrier, they prevent moisture buildup, eliminating conditions that favour the growth of mould and fungi.

2. Liquid-applied membranes

Although less common today, liquid-applied membranes are used as a quick option for waterproofing showers. They are applied like waterproof paint and, once dry, form an elastic layer that protects against water. However, they have some limitations, as they don’t always perform well as a vapour barrier and can wear out faster than waterproofing membranes.

Revestech recommends this option only for projects where speed is key, but always suggests membranes for more durable solutions.

Benefits of Revestech Waterproofing Membranes for Walk-in Showers:

  • Total adaptation to any design: Our membranes fit any shape and size of shower, ensuring complete waterproofing in customised or irregular showers.
  • Quick installation with no complex work: Our solutions are easy to install, saving time and costs. There is no need to remove existing flooring, making them the perfect option for renovation projects.
  • Long-term protection: Revestech membranes are designed to last the entire lifespan of the shower, protecting against leaks and preventing the growth of mould and fungi.
  • Extreme water and vapour resistance: Our membranes not only stop water but also block water vapour, protecting the shower structure and ensuring a moisture-free environment.

How to detect waterproofing issues in your walk-in shower?

You may not notice immediately if your shower has waterproofing issues, but some warning signs can indicate that something is not functioning properly:

  • Loose or cracked tiles.
  • Dampness on adjacent walls or floors.
  • Moisture stains on the ceiling of the floor below.
  • Visible mould on joints or in the corners of the shower.
  • Persistent musty smell.

If you notice any of these issues, your walk-in shower is likely not properly waterproofed, and it’s important to address it as soon as possible to prevent further damage.
