Improper Material Selection One of the most common causes of waterproofing failure is the use of improper materials. Different waterproofing materials have different properties and are designed to be used in specific applications.
Waterproofing failure occurs primarily due to sloppy construction practices, such as using the wrong product or installation method. Another common waterproofing mistake is rushing to get the job done. You see, these systems require precision and attention to detail during installation.
Polyurethane and acrylic coatings typically last 10 to 15 years, while more durable options like PVC and TPO membranes can last up to 25 years. Regular maintenance, including cleaning and resealing, can help extend the life of these waterproofing systems.
Remove the old shower liner and replace it with a new waterproof membrane. Ensure the liner is properly sloped toward the drain to facilitate water drainage. Carefully remove the affected tiles and grout using a grout saw and tile adhesive. Install new tiles in place of the damaged ones using tile adhesive.
Over time, waterproofing coatings can deteriorate due to various factors such as the quality of the coating, application method, and environmental conditions. Generally, waterproof coatings are expected to last between 5 to 10 years, but proper maintenance and care can extend their lifespan.
Can You Waterproof Over Old Waterproofing? While it technically is possible to waterproof over existing waterproofing, it is not something we would recommend. Alternatively, we recommend you invest in remedial waterproofing such as that we offer at Remedial Property Solutions.
In fact, the average lifespan of a waterproof membrane is around 10 to 15 years or more. So, as long as you look after your shower, and prevent water from breaching the surface, you will enjoy long lasting relief from water damage.
Poor waterproofing can fail, leading to cracks, mould issues, and structural defects like concrete cancers. Failure of your waterproofing can cause safety issues, significantly reduce the value of your property, and lead to unfitness for occupation.
For an average-sized bathroom, this could mean between $800 to $2,000, including materials, labour and a waterproofing agent. If you have a more complex setup, then the job can go up to $4,000. Bathroom waterproofing costs for just the shower area may be between $200 to $1,000 based on size.
A waterproofing warranty is a legally binding agreement which a company guarantees that some or all its work will be free of defects, typically for a specific length of time, and is normally approved and signed by both the owner of the project as well as a representative of the company manufacturing the product.
If water proofing is not done properly, then dampness can enter your home, and quickly become the biggest threat to your home's strength.
As a general rule of thumb, it's recommended that the best time to waterproof your home is every 3-5 years. However, this guideline can vary depending on the factors discussed above.
Signs of Poor Waterproofing
Peeling or bubbling paint on the walls or ceiling. Drummy-sounding tiles. Water stains on the ceiling. Black mould growth on grout and tiles.
Construction experts recommend applying an intermediate layer of waterproofing over the base coat to enhance the durability and water-resistance of the surface. This coat not only reinforces the waterproofing qualities of the product, but also fills tiny gaps and cracks that may have formed on the base coat.
Waterproofing repairs that will last
To repair damage caused by water intrusion and permanently fix leaks in showers and wet areas, and to meet the Australian standard for installing waterproofing, it is necessary to remove the tiles, repair all the damage, reapply the waterproofing membrane and re-tile the area.
Waterproofing issues identified in common areas are the responsibility of the owners corporation and generally, anything that is within the airspace of your own private lot, such as a bathroom or kitchen including baths, toilets, sinks and dishwashers, is generally the owner's responsibility.

Quality waterproofing systems should last for at least 10 years. However, this is largely dependent on the type of waterproofing materials used as well as the workmanship of the waterproofing contractor. Statistics have shown that faulty waterproofing is among the top building defects.
If you have completed a project without using primer, there's a good chance the membrane will not adhere properly to the substrate. This means you will need to redo all of the work and purchase new materials. A a primer is an inexpensive and important 1st step in the complete waterproofing process.
