Is Your Balcony Waterproofed? Here’s How to Tell and Why It Matters

Waterproofing is critical to maintaining the structural integrity of your balcony. How can you tell if your balcony has been properly waterproofed? The key is to look for signs of water seepage. Check for water stains or discoloration, as any of these could indicate your balcony isn’t waterproofed properly and is vulnerable to serious water damage.

Still not sure? Try out this this simple test. Pour a small, controlled amount of water on your balcony and observe what happens. If the water absorbs into the flooring material instead of draining away, your balcony has failed the waterproofing test.

If your balcony didn’t pass the test, it’s essential to complete a waterproofing protocol to safeguard its structural integrity and longevity. Here’s what you need to know.

The risks of not waterproofing balconies include:

• Water intrusion
• Structural damage
• Rust and corrosion
• Interior water leaks
• Cracking
• Mold and mildew

Water intrusion is a leading cause of structural issues in balconies. When moisture seeps into the structure, it can lead to cracks, concrete spalling, or even compromise the safety of the building. Proper waterproofing acts as a shield, preventing water from penetrating and causing long-term damage. Without it, repairs can become unnecessarily costly and time-consuming.

If you’ve identified damage, be sure to address it immediately. The full repair process requires professional expertise and a tailored scope of work. Generally this process involves identifying the source of water intrusion, repairing structural damage, and applying effective waterproofing solutions. When tackling a balcony repair project, it’s paramount to address these three problem areas that are especially vulnerable without proper waterproofing.  

Damaged Wood

If damaged wood is identified, a structurally engineered truss repair is a cost-effective and efficient alternative to tearing off an entire balcony. This method is as strong, if not stronger, than the original design. It uses wood and metal plates to maintain structural integrity while adhering to the engineer's original truss design.

Unlike most contractors who simply nail wood together, compromising the necessary structural integrity, this approach ensures a more reliable and durable solution. Once the repair is complete, the area is closed up with stucco or a drywall ceiling, seamlessly restoring the balcony's appearance.

Balcony Edges

Balcony edges are a common source of water damage, especially when railings are attached directly to the floor without proper waterproofing. If the area where the railing meets the floor isn't sealed, water can seep into those gaps, leading to damage beneath the surface. This vulnerability makes balcony edges particularly prone to deterioration, emphasizing the importance of effective waterproofing to protect the structure's integrity.

‍Horizontal Meets Vertical

Water can seep into building materials, leading to significant structural damage over time. This is especially true at junctures where different building elements meet, such as where floors connect to walls or columns. These connections are the most vulnerable parts of abuilding and require extra attention, particularly on balconies.

If not properly waterproofed, water will seep into the edges where horizontal meets vertical as seen in the photos above. You’ll notice visible signs of damage caused by a lack of waterproofing in the "before" image. The "after" image highlights the transformation, showcasing the application of the waterproofing membrane, a crucial step in sealing out moisture. Once the final coat of paint is applied, the result will be a smooth, cohesive finish that protects the structure long-term and enhances its appearance.

Ensuring your balcony is waterproofed isn’t just about preserving an aesthetic, it’s about safety and longevity.
