RCC Waterproofing history

RCC Waterproofing is a 3rd generation family owned and operated business.

Established in 1920 by John Romanelli, RCC quickly became the foundation experts, working on some of Toronto's finest residences and architecturally significant structures, including The Royal York Hotel. Even through times of economic depression, John Romanelli was able to grow the business and maintain a high standard of service, which still exists today!

By 1953, Tony Paul Romanelli joined his father and quickly began overseeing the day-to-day operations of the family business. Over the next 35 years, Tony Paul Romanelli continued to expand the business and would quickly become known as a leader and highly respected authority on concrete and foundation problems.


In 1987, Tony John Romanelli started working alongside his father inheriting not only the knowledge of years of foundation and drain experience, but as well the construction history of the city. By 1995, Tony John Romanelli became President of RCC Waterproofing and has now completed over 75,000 waterproofing projects. As Ontario’s largest and oldest waterproofing company, RCC completes more projects on a yearly basis than any other waterproofing company in Canada.

Along with its extensive experience with foundation problems, some of RCC's employees have been with the company for over 25 years. RCC has also been a contributor to the development of waterproofing technology and has invented some of the most widely used waterproofing systems today.

Waterproofing technology has come a long way since 1920! Today RCC works with some of the worlds leading manufacturers of waterproofing materials, to continue fostering the the latest innovations available to the industry. With RCC's experience and knowledge, you can be confident that you are working with the best!
