Waterproofing Membranes: 3 Factors Affecting How Long They Last

So, how long does a waterproofing membrane last? At Metro Sealant, we are often asked this question, but there isn’t a clear answer to it. Basic waterproofing membranes should last at least ten years, but with the correct type and conditions, they may last considerably longer. On the other hand, substandard waterproofing membranes seldom stand the test of time.

The longevity of waterproofing is mostly influenced by three factors: the quality of the membrane, the level of the construction, and post-project preventive maintenance. Read on to find out how each one contributes to your waterproofing solution and what you need to do to make sure it lasts for many years.

The Quality of the Waterproofing Membrane

Every waterproofing membrane has unique qualities that make them suitable for particular applications.

Membranes must be waterproof and robust enough to withstand the natural movements of buildings, chemicals, and severe climates. They must be appropriate for the specific region of a structure, such as an open balcony, flat roof, or moist basement. For example, the Bituthene 3000 Roll offers the best defense against water infiltration. Its high hydrostatic head resistance also makes it useful in areas with higher hydrostatic pressure, such as foundations or basements.

The Metro Sealant team is fully qualified and certified to offer customized advice for every project, and we know every product inside and out. This level of knowledge makes a huge difference.

The Workmanship

The workmanship is the second crucial factor influencing the durability of waterproofing.

About 1% of a building’s expenses go into waterproofing, yet water leaks and the resulting damage can be responsible for 80% of all building defects.

These waterproofing issues are caused by both poor workmanship and inappropriate solution design.

Any waterproofing system’s weak points are where horizontal and vertical surfaces converge. These inherent gaps are a critical area, yet negligent waterproofers rarely pay attention to them. An experienced waterproofer will provide a thorough solution while taking into account the space’s form and surfaces.

Preventive Maintenance

Once you’ve installed a high-quality waterproofing membrane, you’ll want it to last. For that reason, you shouldn’t neglect it after the project handoff.

Birds clawing at membranes, accidents during other trades’ work, extreme storms, and other environmental conditions can all have a disastrous effect on your waterproofing membrane. 

With a preventive maintenance program, a provider can regularly examine your membrane and notify you if they find any places that need remediation. This way, a minor issue can be addressed immediately before it causes costly damage. 

Another significant advantage of preventative maintenance is how it affects your warranty. If you don’t follow simple instructions to maintain the condition of your membrane, suppliers may void a warranty. Nevertheless, if you maintain the waterproofing on your membrane, they may even lengthen your warranty—sometimes by years.
