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.

The fact is, it is hard to tell how much more life your waterproofing may have left without a thorough examination. Sure, basic waterproofing membranes, if they are of good quality, can last around ten years, but under the right circ*mstances, they can last longer.

The length of time that waterproofing will last will depend on the work that was done and what method was used. Most primers and crack sealers have a warranty of 10 years. If you went with exterior waterproofing, it is almost maintenance free and should last for many years.

Generally, waterproof coatings are expected to last between 5 to 10 years, but proper maintenance and care can extend their lifespan. It's important to consider the construction date of the shower and whether it has undergone recent renovations or repairs when assessing the condition of the waterproofing.

For the water vapour to escape effectively it is important that the outer surface of the material is not saturated with water. To prevent this your jacket is treated with a DWR coating (Durable Water Repellancy), but this coating wears off over time and needs to be replaced.

As a general rule of thumb, you should waterproof your basem*nt at least once every five years. This is because exterior waterproofing materials can break down over time due to weather, natural disasters, and more.

Can You Waterproof Over Old Waterproofing? While it technically is possible to waterproof over existing waterproofing, it is not something we would recommend.

While basic waterproofing membranes should last at least ten years, they can last much longer given the right choice and circ*mstances. Conversely, poor quality waterproofing will rarely last the distance.

Many experts would agree that exterior waterproofing typically lasts around three times longer than interior waterproofing and is generally considered a relatively more permanent waterproofing solution. However, this depends on a number of factors.

What are the disadvantages of waterproofing? ›

Disadvantages of waterproofing

Negative side waterproofing does not provide protection from freeze-thaw cycles and is limited to the application of cementitious systems. Water-resistant and waterproof building materials cost more than standard products, and installation might be more expensive as well.

Many waterproofing membranes deteriorate over time, due to exposure to UV rays, harsh environments, aggressive groundwater, or permanent ponding leading to the disintegration of the waterproofing layer. Ultimately this leads to the failure of the membrane.

Instead, bitumen-based, rubber, and cementitious waterproof membranes are some of the most common waterproofing materials used on flat roofs. Here is the catch though, over time, these materials can degrade and lose their effectiveness, which can lead to costly and disruptive repair or replacement projects.

A basic waterproof membrane should last at least ten years. But under the right circ*mstances, they can easily last longer. Poor waterproofing, on the other hand, may not go the distance. Factors like workmanship, membrane quality and preventative maintenance can influence the longevity of a waterproofing job.
