Waterproofing a Balcony or Terrace with Tiles on Pedestals
How to Waterproof Under Tiles on Pedestals
Waterproofing a balcony or terrace is often overlooked when planning a new home. However, enjoying coffee on your private balcony is one of the most common dreams for many homeowners. While envisioning the perfect retreat, it’s crucial to consider proper waterproofing. Balconies and terraces are unique areas of a home that are highly exposed to the elements, including temperature fluctuations, frost, rain, wind, and UV radiation. These factors pose risks not only to aesthetics, such as material corrosion, visible cracks, dampness, and leaks, but also to the safety and structural integrity of the building.
Increasingly, tiles on pedestals are becoming a popular choice for finishing balconies and terraces. This solution is versatile and suitable for both new constructions and renovations in residential and commercial properties. Ventilated terraces are gaining popularity because they address many common problems associated with traditional adhesive tile installations.
Benefits of Tiles on Pedestals:
- Easy Installation and Removal: The installation process is quick and doesn’t require wet works like adhesive application. Similarly, dismantling is straightforward and avoids the need for chiseling tiles.
- No Adhesives or Specialized Underlays: This makes the terrace less susceptible to damage caused by weather conditions, as there are fewer materials that could fail over time.
- Improved Water Drainage: Water is effectively drained through the waterproofing layer beneath the tiles, preventing standing water and minimizing the risk of dampness and efflorescence.
- Flexibility: Ventilated terraces allow for easy leveling of slopes and uneven substrates.
Why is Proper Waterproofing Essential?
A well-designed terrace or balcony is just the starting point. Choosing the right waterproofing materials is critical to ensuring the longevity of the structure. Waterproofing protects against future costly repairs, which are often several times the initial investment in a high-quality waterproofing system.
Key Considerations for Selecting Waterproofing Solutions:
- Durability: Ensure the materials can withstand harsh environmental conditions, including UV radiation and frost.
- Compatibility: Choose products that work with the specific design and structure of your terrace or balcony.
- Ease of Application: Opt for systems that are straightforward to install, reducing the likelihood of errors during construction.
Proper waterproofing under tiles on pedestals ensures not only the longevity of your terrace or balcony but also enhances its usability and value for years to come.
How to Choose Materials for Waterproofing Under Tiles on Pedestals
Before selecting materials for balcony or terrace waterproofing, it’s crucial to consider the desired surface finish. Options include adhesive-bonded ceramic tiles, natural stone tiles, tiles on pedestals, composite or wooden decking, paving stones, or green terraces. It’s also wise to anticipate future changes in balcony or terrace finishes. For instance, a green terrace requires root-resistant waterproofing materials, such as SK W Full Bond – RESITRIX. However, if you opt for tiles on pedestals, there are more flexible waterproofing solutions available.
Sanier recommends choosing waterproofing materials like flexible slurries, hybrid slurries, or membranes (e.g., PVC, TPO/FPO, EPDM films). To ensure durability and safety for years, select materials suited to your local climatic conditions, particularly those resistant to UV radiation.
How to Waterproof Under Tiles on Pedestals
The approach to waterproofing depends on whether the balcony or terrace is:
- Freestanding or
- Above a heated interior space.
Let’s explore the waterproofing process for both scenarios.
Freestanding Balconies or Terraces
- Use weather-resistant and UV-resistant materials.
- Apply flexible or hybrid slurries directly to the substrate.
- Ensure proper drainage to prevent water accumulation beneath the pedestal-mounted tiles.
Balconies or Terraces Above Heated Spaces
- Start with a root-resistant waterproofing layer, especially if considering future green terrace installation.
- Install insulation layers if required, followed by a waterproofing membrane (e.g., PVC or EPDM).
- Seal all joints and transitions meticulously to prevent leaks into the interior below.
- Finish with pedestal-mounted tiles, ensuring proper slope for efficient water drainage.
By carefully considering your current and future needs and selecting the right materials, you can create a durable and functional terrace or balcony that withstands the test of time. Sanier recommends prioritizing high-quality materials tailored to your specific conditions to ensure a successful and long-lasting waterproofing system.
