Melbourne -  Commercial & Industrial Waterproofing 

Australian Waterproofing Standards 

The importance of waterproofing should not be underestimated.

  • Waterproofing accounts for approx 1.8% of building costs. 
  • However water ingress accounts for 80% of insurance building defects.  

According to Paul Evans, President of the Australian Institute of Waterproofing (AIW) and Managing Director of Findlay-Evans Waterproofing, standards in waterproofing can be improved. 


This article by Paul,  first published in Australian Institute of Waterproofing (AIW), discusses  waterproofing standards within the construction industry:  Getting It Right the First Time 

  • Water penetration is one of the most  common causes of building defects.

  • This means anyone with a bucket can call themselves a waterproofer ! 

  • This is alarming considering the consequences of membrane failure and  the devastating effects of water leaks.

Water leaks can be difficult & expensive to rectify.

Choosing Correct Waterproofing System

  • Depending on the structure and need, the waterproofing membrane can either be applied to the interior (negative), such as the case with repairs, the exterior (positive), or in places inaccessible by people (blindside).

Choosing Correct Waterproofing Product 

The first step to choose waterproofing membrane system:

  • Decide between a prefabricated sheet or liquid-applied membranes.
  • What’s the difference between the waterproofing methods?
  • Prefabricated sheets-  should you go with adhesive sheet or torch-on membranes? 
  • Or are Liquid Applied Membranes (LAMs) the right option?

Liquid Applied Waterproofing Membranes

  • Liquid Rubber is a state of the art elastomeric waterproofing membrane offering superior performance and developed to solve the problems that continually arise in the use of conventional membrane systems.
Torch On Membranes

Torch On Membranes - with flame or adhesives.

Torch On Membranes 

  • Membranes are torch welded to the substrate for the best bonding to the substrate and between membranes.
  • Open flames may cause OHS issues.

Sheet Membranes

  • It is important, the seams where the sheets come together are properly treated and sealed. 
  • If the seams are not properly treated and all gaps filled with the appropriate sealer, water may leak through and damage surrounding areas.

Leaking Balconies are a major source of building defects.

Balconies, especially tiled ones, should have correct waterproof membrane installed.

Below Ground Waterproofing Standards (AIW)

  • It is critical below ground waterproofing is done correctly the first time. 

  • It is not worth taking risks,as rectification can be difficult & costly. 

  • Using low cost waterproofing products & methods for below ground tanking is short sighted at best.

Waterproofing Using Bentonite

  • With bentonite panels, the seal doesn't form until the foundation is backfilled and water reaches the panel.

  • Some waterproofers are nervous about using bentonite panels. 

  • With other products, you can inspect the finished waterproofing application and confirm the integrity of the seal before backfilling. 
  • Suppose something goes wrong?

  • It's a nagging question for  many waterproofers.

Roof Waterproofing



Concrete Roof

  • A flat concrete roof with leaks should be repaired right away as concrete is susceptible to spalling, concrete cancer.

  • Concrete repairs are important to prevent and contain the leaks.

  • Underground car parks with failed waterproofing system can cause devastating structural damage.

  • A flat concrete roof needs a water proof method that will bridge over cracks and also move with the concrete.

Metal Roof

  • A metal roof, particularly a corrugated one, it is vulnerable to damage and moisture. 

  • Each panel is attached to metal or wood trusses using screws or steel nails, which can rust. 

  • Over time, they can lead to leaks, which can be repaired when you locate the source of the problem.
