Bathtub rim not checked into the vertical wall, not recommended as this may cause moisture to migrate through either the rendered walls or the stud timber frame behind the villa board.

 

Its recommended that the bathtub rim is to be in the vertical walls by a min of 20mm.

Window in the shower recess Not Recommended, as moisture may migrate throughout the wall cavity and may cause damage to the structure and could have health issues, example Mildew,and dampness

This image shows the PVC corner cone installed correctly to ensure flexibility as this is where the pressure movement of structure is high.

This image shows a rear view of where the PVC

membrane is installed. In this case onto a steel structure or timber structure. Our AAA Australian Waterproofing method we use the roof flashing principle.

Figure 7.1 The End Result 

AAA Australian Waterproofing Technology & Solutions enjoys communicating with other trades, thus taking the pressure off the Owner/Builder. Here is an example of the method we use to ensure complete waterproof result when the post of the Balustrade is installed after waterproofing. 

 

In this scenario we then install a flexible PVC boot and welded down to the main balcony membrane area thus eliminating any moisture entering the house.

Spigot Pierces PVC Membrane after Installation.

Figure 8.1 Solution.

This is another example on how to waterproof in a high risk area whereby; in this example a Spigot has pierced through a PVC membrane after the membrane had been installed. 

Notice the PVC tape which has been installed around the Spigot and onto the main PVC membrane. In this scenario the PVC welds itself

to the Spigot for a perfect seal.  

Figure 9. Close up of a step-down into the bathroom

The proper way of preparing for waterproofing is to construct a stepdown into all wet areas by 60mm or more. Its recommended of this method.

Figure 9.1 Wide shot of the bathroom

A wide shot of the bathroom floor. This method is best for all wet areas to help waterproofing to achieve it’s goal and be as successful as possible to eliminate any dangers of moisture escaping the bathroom. This also helps tilers to tile level to the outside area.
