Frequently Asked Questions

how do i know if i have a leaky building?

Most issues with weathertightness aren’t obvious. However, if water is dripping or pooling inside your home when it rains, you are likely to have a leak. You can also look out for:

  • sagging of ceiling linings
  • corrosion of fixings such as screws and nails
  • uneven floor surfaces, like the lifting of vinyl
  • mould or fungi formation on surfaces (although this is often due to poor ventilation)
  • musty smells
  • swollen materials such as skirtings and architraves
  • staining or discolouration of materials or surfaces
  • stained or rotting carpet, or rusting of carpet fixings.

Is my home more likely to leak than others?


Certain areas of your home will be more prone to taking on excess moisture than others, and there are some common building features that can cause problems with weathertightness include the following:

  1. Flat roofs, or roofs with parapets
  2. Roof to wall junctions
  3. Pergola fixings
  4. Handrail fixings
  5. Lack of flashings to windows and penetrations
  6. Decks over living areas
  7. Balustrade to deck or balustrade to wall junctions
  8. Clearances at bottom of claddings
  9. Level of ground outside is above interior floor level

 If your home has some or all of these features it does not necessarily mean you have a leaky home, but it is worth getting it checked.

I have a leak

My membrane is leaking

From over 32 years of installing many of the industry's membranes, we now have found the absolutely best membrane available. It can withstand ponding water and seal off any situation, removing your leak.

I've HEARD THAT ALL solid plaster homes leak

The idea that only solid plaster homes leak is a misconception. All homes – no matter what type of construction – have the ability to allow water in, and if you look at a weatherboard home you will find the same points of entry around the aluminium systems. Viano has created a system that seals off a monolithic plaster clad structure, thus we have the first of a new generation of coating systems that prevents water entry but still allows the building to breathe.


Until recently, the only available remedial solution for a leaky building required a total removal of the outer substrate and then re-cladding. This is a very costly approach, and in some cases could cost as much as the original building construction. Viano's Liquid Blue Skin (LBS) is a far more accessible solution, providing a highly effective weatherproof protection membrane of “breathable” BEP Blue Barrier, along with the installation of electronic moisture-sensing probes, and a durable topcoat paint finish.

What can I do to HELP my monolithic building?

As with all buildings and building materials, an annual maintenance plan is required which we provide after installing either an encapsulation system or an elastomeric system – both of which are a liquid coating designed specifically for monolithic buildings.

How do I soRt out my old membrane?

K1 liquid infused Kevlar membrane will rejuvenate your membrane to the highest standard available, giving it a second life.

I’m after THE best product for waterproofing

This will be determined by its application purpose – for some it may be aesthetics, while for others it needs to be trafficable. Contact us so that we can discuss the best solution for you.
