Daniel Caruana of Danrae Group demystifies the waterproofing game for us. We talk roofs, balconies, bathrooms, and Daniel answers the question: why do we see so much remediation work in this area?

  1. Thanks Amanda

    We have 3 problems in our buildings
    1. We have Investors flying in and flying out with thousands of dollars gains who are not interested on the long term but their quick gain.
    2. Fair Trading should be the one informing people of the best material to use and the qualified people to engage.
    3. Do not have a regulator to protect us a consumer.

    Thanks again!!


  2. Thanks for the podcast on waterproofing the industry definitely needs more of them. Architects engineers need to be educated as well.
    Fernanda I don’t think a regulator such as fair trading would be a great idea. The licencing system, unfortunately, has been a great solution either.
    Introduced over 25 years ago and we are still having problems.
    The problem with all waterproofing is will the people following the waterproofer damage their work? After more than 15 years doing (mainly remedial) waterproofing and building repairs I can tell you the answer is yes of course.
    Also now acting as a supplier I know BC’s, owners all want to fix it as cheaply as possible. Want a solution to problems that have been ongoing for years.
    Unfortunately, external areas or other areas where there is no living space (say a bathroom or kitchen over a garage) don’t require waterproofing according to regulation. This about the economics of building (low cost is better…not)
    Where water penetrates sheet or liquid membranes which are damaged or incorrectly installed this water will often cause delamination of the membrane system.
    In many instances, water penetrations can’t be treated from where the water is coming from without high costs. eg. basement walls & floors
    So you see buildings with water coming through slab joints, cracks block walls, some drained into stainless gutters hung across the roof. The water running through these penetrations is causing damage to the structure shortening its longevity.
    Practical solutions need to be found and a large part should have occurred in the design phase. But if it didn’t you still need to find a solution.
