The leak at the entrance was from the balcony.

"Sealing Success: How Urethane Waterproofing on a Balcony Solved an Entrance Room Leak"

Introduction: Water leaks in homes can be both disruptive and perplexing, especially when the source is not immediately apparent. In a recent project, our team encountered a challenging scenario where the entrance room ceiling of an apartment was suffering from persistent leaks In Yamashina ward, Kyoto. The source, as it turned out, was the balcony above. This article recounts our journey of identifying and solving this leak issue using urethane waterproofing.

The Discovery: Residents were troubled by a leak in the ceiling of their entrance room, particularly during rainy days. Our initial assessment involved a thorough inspection of the room and nearby areas. The breakthrough came when we noticed significant damage on the balcony directly above the entrance room.

Why Urethane Waterproofing? Urethane, known for its durability and excellent waterproofing qualities, was our material of choice. Its ability to form a seamless barrier against water makes it particularly effective for outdoor applications like balconies.

The Process: Over the course of four days, our team undertook the task of waterproofing the balcony. Here’s a brief outline of the process:

1. Surface Preparation: We started by cleaning the balcony surface, removing any debris, and repairing visible damage.
2. Urethane Application: We applied a layer of high-quality urethane material, ensuring thorough coverage to prevent any future leaks.
3. Curing and Testing: After the application, we allowed adequate time for the urethane to cure and then conducted tests to confirm its effectiveness.

The Outcome: The results were as we hoped – the waterproofing was a success. Following the treatment, the entrance room ceiling remained dry, even in heavy rainfall, marking the end of a frustrating period for the residents.

Conclusion: This project was a testament to the importance of accurate problem identification and the effectiveness of urethane as a waterproofing solution. It highlights how sometimes the solution to a persistent problem lies in looking beyond the obvious and addressing the root cause.
