    RTT Sealant has completed numerous waterproofing projects for Australia Fair Shopping Centre in Southport
    on the Gold Coast QLD, including sealing concrete cracks and expansion joints in the car parks as well as box
    gutters and ridge capping on the roof. I found the application team to be very accommodating and
    professional and their products have proved to be very effective and reliable.

  • Aaron Butteriss | Queensland Government

    Hi RTT Sealant, please pass on to your team that we are very pleased with the product. As you may
    remember the roof at Coorparoo Education Precinct was in need of replacement but due to the cost of
    removing and replacing the aged roof mounted air conditioning units it was not possible with the limited
    budget available. Your roof coating solution eliminated the need for removal. All roof leaks were fixed after the product was installed. The team that attended to carry out the work was a pleasure to deal with, always acting in a professional and safe manner.

  • Simon Gadd | Ozcare

    RTT Sealant completed major roof waterproofing and restoration projects at our facilities in Brisbane and Townsville. The projects were a complete success and not only does the roof look brand new with its bright white solar reflective finish, there are no more leaks into the buildings. Given the size and difficulty of the applications, the hard working RTT Sealant team was up to the task and did a great job. We look forward to working with them on future projects.
