What is waterproofing?

Waterproofing is essentially using a protective membrane to stop the flow of water transferring from domestic wet areas to dry areas in both internal and external situations. Waterproofing provides a protective barrier from water damage usually to the wall and floor and especially for rooms on the ground floor. Typical situations that require internal waterproofing are those spaces that encounter water and condensation such as balconies, bathrooms and showers, and basements with peeling paint often seen as the first signs of water ingress.


Water and moisture growth is extremely dangerous and if left unattended in residential or commercial buildings, will cause major structural problems as well as rising  damp and mould issues.

Flooding is a major issue for many homes requiring better balcony waterproofing

Excess moisture in bathroom tiles results in remedial waterproofing and repair

Defective waterproofing is a major issue

Unfortunately the building and waterproofing industry are now seeing the results of poorly followed standards. Since 2012, over 80% of residential buildings has suffered from poor balcony waterproofing services resulting in balcony leaks, water ingress, balcony damage which in some cases have led to damages to balcony repairs of an entire floor. 


There are many reasons for having leaking balconies.  Some builders have failed to build sufficient falls into the substrate of multi level apartments. Other reasons may be due to thermal fluctuations causing tile growth whilst compressing the expansion joints. In this situation, dark tiles are more susceptible than light tiles to expansion,


Many contractors are not waterproofing specialists, don't have waterproofing systems and quite simply, fail to comply with Australian waterproofing standards. A common situation involves bathroom renovations where inadequate bathroom waterproofing has been carried out by unqualified or inexperienced contractors to save on costs. This is noticeable by looking at the floor tiles affecting the bathroom floor and shower walls.


Water damage can affect an entire bathroom floor, the shower recess as well as bathroom walls which is why only licensed waterproofing contractors should be used to waterproof a bathroom or balcony area.

Why use professional waterproofing contractors

According to the Australian Master Tilers Association, defective waterproofing is a major building defect in Australia. It is actually listed as one of 3 worse building defects that can happen, with water leaks often causing the same structural damage to a property as would termites. Generally, waterproofing problems are caused by poor workmanship from waterproofing contractors. Leaks in bathrooms are unimaginably common especially after a bathroom renovation while balcony tiles can undergo serious damage after heavy rainfall.


We deal with leak repairs on a daily basis and always follow the Building code of Australia applying the Australian standards in our work. All our jobs are given the same high quality project management. If you need to waterproof a bathroom or fix a leaking balcony, then go with a waterproofing expert for peace of mind.


Within the waterproofing industry, the most common problems associated with strata buildings is internal leaks and water penetration causing cracking to both internal and external structures. Frequently this means that leaking balconies, showers and basements are prime areas of concern when it comes to waterproofing problems. The reasons for this are varied but primarily are caused by ineffective building designs caused by commercial pressures from architects, builders, concrete and waterproofing contractors. This is why we often hear of problems associated with new high rise buildings that have been developed throughout Sydney. 


If water leaks are not quickly addressed either in balconies, showers, roofs, laundry or basements, there is a strong likelihood of very expensive remedial waterproofing and even potential re-builds that need to be done.  Using waterproofing contractors to address wet area waterproofing issues will result in protecting your carpets, walls and timber floors as well as preventing structural damage on your external concrete slabs and tiles.


When it comes to balcony waterproofing, the most common problems we see are problems with the joints leading to tiles dislocating and tearing the waterproofing membranes. To rectify something like this could cost up to $20,000 which is why it pays to get proper waterproofing contractors to do a visual test if there are concerns. 


Similarly, a study showed that almost 50% of bathroom areas from strata developments were non compliant in terms of leaking. This unfortunately means that additional bathroom waterproofing should be considered particularly if you seen signs of adjacent leaking from shower areas before the expense of re grouting and re tiling occurs.
