How Long Does Basement Waterproofing Last?

How Long Is Waterproofing Warranty

If your basement is wet and musty due to leaking walls or floors, basement waterproofing is the solution. Without such a solution in place, your home could experience the pitfalls of water damage, from health problems due to mould growth to serious structural problems due to rotting wood. If left untreated, your home could experience additional costly repairs, including emergency plumbing services.

When it comes to basement waterproofing, the first step is to determine the source of your wet basement. Is high humidity the source, or is outside water entering your home? Ensure that your downspouts and gutters are working correctly and that the grade of soil surrounding your foundation is also properly diverting water away from your home.

Depending on the type of basement waterproofing you choose, it can be an investment in some cases (although one that certainly generates a significant ROI); naturally, one commonly asked question is, how long does it last?

Basement waterproofing is not a one-size-fits-all type of solution. Ultimately, there are likely several different factors contributing to your wet basement, from cracking basement walls to improper backfilling, in addition to the home’s foundation, which means that methods used for waterproofing vary from home to home. Some houses may also need to use several different waterproofing methods.

In general, basement waterproofing methods include: waterproofing primers and paints for both the interior and the exterior (which effectively act as sealants), crack injections, exterior excavation waterproofing (such as a French drain system) and interior excavation waterproofing (a sump pump). This means that the length of time that basement waterproofing lasts varies depending upon the method(s) used.

Waterproofing primers and crack injections are not permanent, but most of these products have a warranty of ten years. However, if they are correctly applied, they can last even longer. 

Professional basement waterproofing ensures that the proper method is used, thereby extending its lifespan. The exterior excavation waterproofing method is more permanent, lasting many years. It is also virtually maintenance-free. The downside, of course, is that it is a significant investment.

A wet basement poses a serious risk to your home. It invites mould to grow, which can create a health hazard and damage the house’s foundation. These can be costly issues to repair, which is why basement waterproofing is a sound investment. If you’ve already had it done, you may be wondering how long it lasts and how to care for it. Below, you’ll find everything you need to know for optimal protection.

Because every basement is different, waterproofing applications can vary. Due to this, it isn’t easy to establish a universal amount of time it will hold up. If you’ve had an interior and exterior primer and paint sealant applied that has experienced minimal stress from water, you’ll receive roughly ten years of use — a common warranty time among basement waterproofing products. However, constant moisture and water exposure may decrease its lifespan.

Does Basement Waterproofing Last?

Every basement is different, as ground conditions and use will vary. When you specify construction materials to prevent water ingress, you’ll want answers to the question: how long does basement waterproofing last?

A common timespan for a waterproofing system warranty is ten years; however, there’s no one-size-fits-all answer and, whether or not a 10-year prediction proves to be accurate will depend on several variables:

Design expertise

Including a waterproofing specialist on the design team from the start will help to avert problems later on, from building and contents damage to the hazardous mould. Not only that, but the LABC Warranty requires that you engage a waterproofing specialist as part of your design team – that means a Certificated Surveyor in Structural Waterproofing (CSSW) or the equivalent.

Workmanship

The most common reason for waterproofing to fail is down to errors during installation. There are two basic principles to bear in mind here.

  • Firstly, as much as 90% of all water intrusion problems occur within 1 per cent of the whole building or structure’s exterior surface area. That means it only takes one small area of failure to render a system defective.
  • Secondly, according to the 99 per cent principle, around 99% of waterproofing leaks are attributable to causes other than material or system failures.

For this reason, it’s always wise to consider the contractor’s experience. Whether they have specialist expertise in applying your chosen system – perhaps they’re part of a licensed applicator scheme, for instance. With the best will in the world, the manufacturer can’t be held responsible, should the system fail, if it has been incorrectly installed. It’s highly likely to be a condition of the system’s warranty that it’s thoroughly inspected once in place for precisely that reason.

On the upside, appropriately specified by the designer and applied by an experienced contractor, a waterproofing system should meet its warranty and potentially exceed it, barring exceptional circumstances.

If you need to find a reliable waterproofing contractor, membership of a scheme such as CGS assures certified competency.

Environmental/ground conditions

To prolong the life of your waterproofing system, taking measures above ground can make a big difference. For example, maintaining an incline at the exterior’s ground level (sloping away from the structure at a grade of at least two per cent) will help water to run off, which will be beneficial to the preservation of the structure’s foundations.

Gutters and drainpipes have a role to play, too – simple maintenance such as keeping gutters clear will also have a positive impact in directing water away from the basement’s walls and foundations.

What happens when water ponds by the foundation? Well, clay soil such as London clay will expand when wet. This swelling can result in lateral pressure on the walls’ exterior. The result is an increase in the likelihood of cracking and movement, while the freeze-thaw cycle can come into play during cold weather, with the potential for causing further damage. Repairing damaged foundations can be hugely expensive so that preventive measures will deliver savings in the long term.

Combination waterproofing systems

Planning at the design stage is an important aspect in determining the long-term efficacy of a waterproofing system. Any waterproofing design should aim to avoid the necessity for expensive remedial measures such as external excavation further down the line. Using a combination of systems to achieve the appropriate dryness level is the best way to avoid this worst-case scenario for waterproofing failure.

In practice, this means considering the requirements of BS 8102 for varying types of waterproofing protection: Type A barrier protection and Type B structurally integral waterproofing systems should be used together for optimal effect, while Type C drained protection, which incorporates an internal water management system, is an extra precaution to achieve the highest level of protection. 

Within any combination system, the re-injectable hose can be used in the joints between the basement’s walls and floor slab. This measure addresses structural movement by providing the option to check and reinject joints later as the need arises.

In conclusion, a poorly waterproofed, leaking basement devalues the entire structure. It undermines its integrity, so basement waterproofing should be regarded as a measure that offers a real return on investment. While it might be tricky to attach an exact timescale to that investment, ten years is a practical yardstick. Follow best practices, and you can be confident that you will have a positive effect on the performance and longevity of basement waterproofing.

There are various ways that water can flood home and various ways to repair those issues. To find out how long the basement waterproofing process will take, it is important first to determine if this is a plumbing issue or a seepage issue. Many times, both can disguise themselves as the other. A reputable, knowledgeable professional should be able to tell the difference. So, if it does turn out to be a Waterproofing issue, what then? Well, there are three ways water can come into the foundation; Over-the-Top, Through, and Under.

Over-The-Top Seepage is mostly solved with an exterior solution. The water is sealed from coming in from the outside, and many times landscaping is involved as well. From the waterproofers’ aspect, their work is generally minimal. Exterior Sealing, the solution to Over-the-Top Seepage, is performed fairly quickly. It must be over 40 degrees and dry to perform the work so the sealants used can adhere properly to the foundation. That limits the work to be done anytime but in the winter and while it is raining.

Through the foundation, seepage (Foundation Cracks, Pipe Penetrations, Window Well Drains, Tie rods, etc.) are generally fixed via Epoxy Injection for the cracks and voids and some PVC piping for the Window Well Drains that runs to a sump pit. Depending on the severity of the issue and how many issues there are to solve, it can be completed within a day most of the time. Window Well Drains take two technicians approximately 2-3 hours to complete. A Foundation Crack will take 1.5-2 hours to complete per crack. Pipe Penetration and Tie Rod Injections take approximately 1 hour per repair.

As more of these repairs are added to the ticket, the time it takes to do each repair goes down. This is accomplished through efficiency in work (think Ford’s assembly line). We can get more efficient as we do more of the same work, which lowers the prices as more is added on.

When we are talking about Seepage from Under the floor, this is due to Hydrostatic Pressure and generally requires installing a Drain Tile System. This entails installing a 4” pipe under the floor, running to a Sump Pit that pumps the water out and away from home. If the foundation already has a Drain Tile, replacing the Sump Pump or digging a deeper pit may solve the issue. Discharge Line issues (where the water goes once outside) can sometimes solve it as well. Both of these issues can be solved in a day or less.

If we do need to install a new Drain Tile System, we are on the average timeline of 2-3 days. The amount of work is quite large, as we now need to break concrete, haul out debris, and install a full-perimeter system to mitigate the water. Permits are also involved in these projects, and the inspections can alter the time it takes to complete. Some cities are not very flexible in inspection times, so the job needs to be coordinated well for both parties.

To sum up, Basement Waterproofing timelines can vary depending on what needs to be done. As a general rule, the projects should be encased within three days, many times much less time than that. Most of our repairs are done within a day. It is when we have the larger projects that the timeline can be extended out 2-3 days.

Basement Waterproofing: What Causes Leaks?

Depending on the factors contributing to the cause of the wet basement, there are a variety of different waterproofing techniques that will be used. In most cases, it is likely that are several factors that are contributing to your leaky basement; these factors include:

  • Cracking basement walls
  • Improper backfilling
  • Problems with the home’s foundation
  • Clogged gutters/downspouts

The type of waterproofing methods used for waterproofing will vary from home to home based on the cause of the water. Some houses may even need to use a combination of several waterproofing methods to achieve a dry basement.

Types of Basement Waterproofing Methods

Common basement waterproofing methods include:

  • Waterproofing primers and paints are used on both the interior and the exterior and act as sealants.
  • Crack injections
  • Exterior excavation waterproofing, such as the installation of a French drain system.
  • Interior excavation waterproofing, such as the installation of a sump pump.

This means that the length of time that basement waterproofing lasts varies depending upon the method or methods used. Methods such as waterproofing primers and crack injections are not a permanent, lifetime solution, but they typically have a warranty of 10 years. If applied by the expert team at Pittsburgh Drain Guys, they can last longer.

By hiring a professional, you can ensure that your basement receives the proper waterproofing treatment, which also extends the product’s lifespan. Using methods such as excavation waterproofing, such as a French drain, provides you with a permanent, low maintenance waterproofing solution.

How Can I Get the Most From It?

It would be best if you minimised water exposure both internally and externally. If you have any spills inside your basement or leaks, they need to be addressed right away. You should check plumbing fixtures regularly. To limit exterior water exposure, make sure your gutter system properly diverts water from the foundation. You should clear out gutters regularly and make sure a proper incline is maintained around your home so that water is pushed away. You’ll avoid the need for expensive foundation repair and can be confident that your home is protected.

While there are DIY basement waterproofing options available, it’s always best to work with professionals, even for simple crack sealing. They will bring the necessary tools and experience to ensure lasting results.

Waterproofing Lifespan

Unfortunately, waterproofing is not a one-size fit all solution. There are several factors to consider. You will need to look at your basement and foundation and see if any cracks exist and how the groundwork is laid. Because every home is different, the way you waterproof and what solution you use will vary from home to home.

Generally speaking, waterproofing materials will include a primer and paint for the interior and exterior of the dwelling. When it comes to a basement, you want the interior walls and the exterior to be coated well. Primer and paint will act as a sealant for the space. Crack injections will also be needed when you have cracks in your foundation or basement walls.

In most cases, a primer and crack injection will have a lifespan of around ten years. If they are applied perfectly, the waterproofing capabilities should last at least ten years, if not longer. When a professional handles the waterproofing process, the lifespan of the product can be extended. In combination with exterior land grading and excavation techniques, water will stay away from home, and you can see the waterproofing product last even longer.

If you have recently moved into a home and appear to have issues with the foundation or basement, it is important to consider waterproofing. Doing the work now will give you peace of mind for several years until you need to repeat the process yet again.

Benefits of Waterproofing

We all know that water can damage the home, but do you know just how much damage water can cause? When water seeps into a basement, it can destroy flooring and belongings as well as create mould and mildew, which leads to even more damage in the home, along with health issues. 

Water damage is messy and costly to clean up. Taking the proper precautions with waterproofing ensures that your home will not be affected by water damage and that you can avoid any unwanted, costly repair needs in the future.
