Why Waterproofing Membranes Fail

Why waterproofing membranes fail. This video outlines the most common problems in concrete waterproofing using different waterproofing membrane systems.

Very informative however the researcher should recommend what are the latest technology for water proofing

Most of this is quite true for membrane failures, but there are many technologies for membrane protection that are great when installed correctly. Just relying on concrete admixtures, crystalline additions, other pore blocking technologies which is referred to here, is just 1 approach to watertight construction. But concrete cracks, and also has many placement considerations that can upset this also. Dry basement construction is about 3 types of protection as per British standard. 1. is membrane protection. 2. is integral concrete quality plus the joints / CJ's using waterstops. 3. Drainage design. This is a layered approach to dry basement design, and covers multiple lines of defense, as you say, application issues are common. You have to plan for success and have all parties working to a common cause. Having QA and hold points verified at key times, will improve any application. Adding pore blockers alone is perilous and disrespectful to understanding the overall dynamics of waterproofing.

25 years ago I had some Ice and Water Shield left over so I put it on, 2-ply, on a patio as a "temp" solution. This stuff is only approved as an underpayment. It is still in service and has not even deteriorated, de-bonded, or become stiff. It has never leaked. What matters is if your installer is a professional and understands his/her materials. That is the real take-a-way here. The alternatives? Well, over competency, you have none (also the take-a-way here). You (or someone later) can pay for your mistakes, or, you can pay a professional--who might make a mistake. Or wait till we can just print it.

Nice 3D representations, but I do not agree on stating that TPO o PVC membranes do not work (or even bituminous ones). It is always required some kind of protection for the concrete so water doesn't corrode the rebars or damage concrete. Fully adhered membranes work perfectly since these can be either post o pre applied and the adherence is both chemical and mechanical to concrete. In severe cases compartment systems can be used to have a segmented waterproofing, so in case there is a punctual failure it will only affect one specific compartment. Several solutions such as wet applied membranes, fully adhered TPO membranes, PVC membranes with compartment systems. injection hoses and polyurea, among many others, might be the solution. Bituminous membranes stand approximately up to 0.5 bars, while fully adhered TPO membranes can stand up to 2 bars. It cannot be said that a technology doesn't work if you don't know the factors such as water column, water quality, durability expectations (service life), available budget, level of permeability required based on use type (according to BS 8102:2022).So, my recommendation, don't generalize, bituminous membranes in some projects that are not exposed to agressive conditions or don't require a long service life. Another point: if by any reason the membrane fails, you can always use injection resins as a corrective way to stop water in negative pressure.

video ends with no answer given, ...new technologies exist... but doesnt says which ones =(

[markproulx]

Over four minutes of criticism with no information regarding best practices.

[ronaldc]

4:45 Can you name some of these newer technologies?

[paulbains]

I did not have problems with my membrane leaking for 15 years, until new development next door began blasting to remove rock . Considering an alternative ?

[darrenrd]

I think they are referring to either waterproofing concrete and/or liquid applied. Hope that helps.

[manishasharma]

No overlapping of the membrane edges done, does it effect its durability and functionality?

[SonnyDarvish]

the older I get, the more problems I face. what should I do now if membranes fail? are we doomed?

🎯 Key Takeaways for quick navigation:

00:19 👷‍♂️ Waterproofing membrane installation requires skilled labor and 90% of failures are due to poor workmanship.
00:32 ❌ Picking an inappropriate membrane for the intended application can lead to failure of the waterproofing application.
01:03 💧 Any debonding of the membrane leads to water penetration into the concrete.
01:26 ⬇️ Certain membranes not fully adhering to the concrete surface make them unsuitable for below-grade applications.
01:39 🌧️ Applying a membrane to a damp, wet or uneven surface can cause debonding.
01:52 🔄 Lack of adequate priming prior to waterproofing application can result in failure.
02:19 🔗 NOT fully bonding overlaps can cause potential breaches in the waterproofing layer.
02:32 🎈 Failure to properly prime a surface may lead to air becoming trapped under the membrane, causing debonding and blistering.
03:01💔 Damage such as puncturing and tearing from construction activities often cause breaches of the waterproofing layer.
03:30 ⏲️ Over time, waterproofing membranes may deteriorate due to exposure to the environment, which can lead to failure.
04:24 🔄 In conclusion, new technologies that permanently reduce permeability and improve concrete properties are recommended as a solution over membrane applications.

So what should be applied instead of membrane??

[howardrickert]

Application accounts for 90% of failures, but skilled labor placed it... what?

[jamesrgibsonha]

Good arguments for nor using membranes. What solutions do you recommend instead?

[anshumandriwedi]

Polyasphratic with epoxy primer is the best solution for these problems.

Dimple membranes called as drainage sheet are one of the most versatile and effective materials for waterproofing of the buildings. It is (HDPE) High Density Polyethilen based and provides speed in your construction projects, sustainability and environment friendly solution.

[boedillard]

Ummm - so what are the newer technologies that solve this issue?

[nathandsnow]

the only take away I got, was the things NOT to allow when installing these various types of waterproofing membranes.

[nureone]

what cause waterproofing failures in pre cast concrete or IBS ?
