Water Leaks are a NIGHTMARE

A decade of drought is over And are your projects watertight?

Over the last 10 years most waterproofing membranes have never really been tested

due to lack of water.

Page 3: Waterproofing Membrane Failure

Now after consistent heavy rainfalls in Melbourne, unfortunately there any membranes installed over the last decade that are simply not doing their job.

Page 4: Waterproofing Membrane Failure

Incorrect choice of membrane or poor installation may have managed to get by

when there was little rain. Until now......

Balconies are leaking all over Melbourne!

Classic signs of membrane failure The adhesive and possibly the membrane are re-emulsifying and leeching up through the joints of tiles.

Page 6: Waterproofing Membrane Failure

• This is caused by insufficient falls/ incorrect membrane which are not designed for ponding (standing) water.

• This balcony requires tiles and membrane to be removed and re-installation of a new membrane.

• If falls cannot be made greater (new screed) then the new membrane, such as Liquid Rubber, needs to able to "HOLD" water and re-tiled.

• The damage to the structures below is often extensive due to slow water ingress causing rotting timber structures and rusting of steel components.

• With recent heavy rain many balconies are just not waterproof.

• Unfortunately we are seeing water damage due incorrect installation all over Melbourne. Water damage to associated structures is immense.

Entire balcony requires membrane replacement

Another balcony with membrane failure.

This entire balcony had the surface removed and a new Liquid Rubber waterproof membrane re-installed after water leak in the rooms below caused the tenants great inconvenience and damage.

Some simple tips to implement to help avoid water egress on

projects. • The flow of water on any job is something that

requires planning and proper management.

• All too often we see this component regarded as the "she'll be right mate" attitude.

• Although we all admire our laconic attitude, we do need to be more diligent in planning ahead when it comes to site water management.

• Design and plan the right method of water removal.

• Ensure surfaces that require waterproofing are made and kept in good condition, this minimises the work and cost required to "make them right" for coatings.

• Concentrate on the most vulnerable places of water ingress. One of the most common causes of water leaks is at the base of below ground walls where wall meets footing or edge beam.

• There are a number of inexpensive and simple install methods to minimise this problem.

• The external coatings should not have any location for water can sneak in.

• We see many below ground walls covered with a membrane that simply finishes at the bottom of the wall and leaves the vulnerable joint at the base exposed to water ingress.

• Liquid Rubber combats this as it is applied over the top of footing, over the junction and up the walls in one "seamless" membrane.

• As it is spray applied, it gets into tiny holes and cracks that often don't get filled with conventional roll out types of membranes.

Of course the best way

to avoid these nightmares is

to have your Waterproofing

installed correctly the First Time.
