Grappa Restaurant, The Rocks

When working on heritage-listed or historically significant buildings, waterproofing becomes more than just a technical task—it’s about protecting the past while ensuring the structure performs to modern standards.

Optimo was recently engaged to deliver waterproofing solutions across multiple wet areas within a beautifully refurbished historic building. The scope included the commercial kitchen, bar, and bathroom facilities—each presenting its own set of challenges due to the building’s age, structure, and materials.

In high-traffic zones like commercial kitchens and bars, durability and compliance are critical. These environments demand robust waterproofing systems capable of withstanding constant moisture, cleaning processes, and heavy use. Optimo implemented tailored solutions designed to meet Australian Standards while integrating seamlessly with the refurbishment works.

Bathrooms required a more detailed approach, ensuring complete sealing in confined spaces without compromising the building’s original character. Careful preparation and product selection allowed for a high-performance finish that protects against leaks and long-term water damage.

Projects like this highlight the importance of experience in both remedial and new waterproofing applications. By combining technical expertise with an understanding of heritage constraints, Optimo delivered a result that safeguards the building’s future while respecting its history.

If you’re undertaking a refurbishment or working with a heritage property, choosing the right waterproofing partner can make all the difference.
