The Consequences of Standing Water on Balconies and Terraces
Why Invest in Effective Waterproofing?
Standing water on balconies or terraces is not just an aesthetic issue—it poses significant risks to structural durability and the health of residents. Water that fails to drain efficiently penetrates through cracks and leaks, seeping into the building's interior. This increases indoor humidity levels, creating an ideal environment for mold and mildew growth. These microorganisms not only damage building materials but also pose serious health risks, potentially causing respiratory problems and allergies.
Another negative impact of standing water is the corrosion of metal facade elements, such as ventilation grates or drip edge profiles. Corrosion not only diminishes the external appearance but also weakens the structural integrity of these components, which can eventually lead to costly repairs.
Additionally, water pooling on balcony or terrace surfaces can damage the flooring and the underlying insulation layer. If water penetrates these layers and reaches the deeper parts of the structure, it can cause permanent and expensive damage.
How to Prevent Issues with Standing Water?
- Proper Waterproofing and Slopes:
From the design phase, ensure that the balcony or terrace features adequate waterproofing and properly angled slopes to facilitate effective water drainage. - Choose the Right Materials:
Opt for materials specifically designed for outdoor use that can withstand weathering and UV radiation. - High-Quality Waterproofing Products:
Investing in premium waterproofing materials and meticulous application is essential for long-term protection and functionality.
Ensuring a properly executed waterproofing system is the best investment in the safety and comfort of your outdoor spaces. By addressing these issues proactively, you protect your property from potential damage and enhance the longevity and usability of your balcony or terrace.

How to Seal a Balcony to Prevent Leaks?
1. Selecting the Right Materials
We offer a wide range of waterproofing materials perfect for protecting balconies and terraces:
- EPDM, PVC, and TPO/FPO Membranes: Durable and flexible solutions that effectively protect against moisture. These membranes create a strong waterproof barrier between the substrate and the flooring, suitable for ventilated floors, resin, or ceramic tiles.
- Mineral Slurries: Examples include Bostik C750 Flex (UV-resistant and suitable as a final layer) and Bostik Block X701 Terra 2k Flex.
- Hybrid Waterproofing: For example, Bostik Block X911.
- Resins: Such as MC Bauchemie Top Speed.
Each product should be complemented with appropriate primers and additional materials, such as tapes for expansion joints and wall connections. The selection of waterproofing products depends on the conditions and type of finish.
2. Preparing the Substrate
Before applying waterproofing, ensure the substrate is well-prepared:
- Cleanliness: The surface must be clean and dry.
- Smoothness: Remove irregularities and fill in any gaps.
- Priming: Apply a primer to improve adhesion for the waterproofing layer.
3. Ensuring Proper Slope
Make sure the balcony has a slight slope to allow for proper water drainage. This is a critical factor to prevent standing water and potential leaks into the structure.
4. Installing Renoplast Drip Profiles
Select appropriate drip profiles that match your flooring type.
- Material: We recommend high-quality aluminum profiles coated with an anti-corrosion layer. This ensures lightweight, durable, and corrosion-resistant protection, essential for outdoor use.
- Recommendation: Renoplast drip edge profiles are available in a variety of options to suit your project needs.
