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.
For instance, a poorly installed exterior waterproofing system could be outlasted by interior waterproofing done by meticulous waterproofing professionals. The materials used would also be another factor to consider, as well as how well suited the installed solution is to the property’s needs.
So, how long does waterproofing last? The answer for this is that it depends. Many sources would say waterproofing only lasts for seven or 10 years. Luckily, with a waterproofing company like PRO Waterproofers, the quality of the work is so top-notch that they carry a long-lasting 30-year warranty.
In this guide, we explore the topic of “how long does waterproofing last?” and all the factors that contribute to it. Along the way, we’ll also talk about waterproofing as an investment and if it’s really worth it depending on your individual needs.
Before we talk about how long waterproofing lasts, let’s take a closer look at it as an investment. Is it worth it? And is it worth it even if it may need touch-ups or replacements every few decades? This all ties into how long foundations last.
In general, concrete foundations have a lifespan of around 150 years. If you live in a much older home, this could be a worrying thought.
However, high-quality waterproofing would help add to the lifespan of a home’s foundation by protecting it from water damage.
To continue analyzing waterproofing as an investment, let’s talk about how waterproofing protects your foundation.
Exterior waterproofing protects your home’s foundation by keeping it completely dry. This prevents the water from seeping through and worsening the cracks that are already there. It also prevents mould from growing on the moist walls. Mould can actually degrade concrete, making it more porous over time.
When exterior waterproofing is paired with a weeping tile with a sump pump drainage system, it will prevent water from pooling around your home’s soil. When you do this, you decrease harmful hydrostatic pressure and prevent soil expansion which could also put a strain on the foundation walls.
For all the reasons above, many agree that although exterior waterproofing may not last forever and the fact that it would need touch-ups or replacement every few decades, it is still considered as a worthy investment.
Aside from all of these, you also get to have a dry basement that essentially increases the amount of livable space in your home.
The lifespan of waterproofing can be seven to 10 years. At PRO Waterproofers, the quality of our work extends the exterior waterproofing lifespan to 30 years. In order to achieve this kind of longevity for our waterproofing solutions, it takes meticulous work, high-quality materials, and more.
Exterior waterproofing is a residential preservation solution that needs to resist environmental forces. Mainly, these forces include hydrostatic pressure and capillary action.
Hydrostatic pressure is the force exerted by stagnant water. This can come from water-saturated soil or a high water table. Meanwhile, capillary action is the movement of water through the small pores present in concrete.
For waterproofing to last longer and effectively address the above problems, PRO Waterproofers offers the following solutions:
One of the critical elements that affect the answer to “how long does waterproofing last?” is the quality of materials used. Moreover, the materials need to be used in a way that allows them to work well together.
PRO Waterproofers use either a high-quality self-adhesive membrane or sprayed-on monolithic coating to create the waterproof barrier. We will determine which one suits a home’s foundation the best.
From here, we also add a drainage board that adds protection to the coating and directs water down to a weeping tile system. On top of that, we also add a layer of protective and insulating foam.
With these high-quality materials all working together, the waterproofing stays solid and unpunctured for decades.
Is it just a matter of making your foundations waterproof? What about other related problems like high water tables, poor rainwater management, or the topography that makes water collect too much at the foundation? You need experts who can identify problems like these so you can prevent repercussions.
For example, if water keeps collecting around your foundation, a waterproof layer will not stop the force that the stagnant water inflicts on your foundation walls. The long-term repercussion of this is that the wall may eventually bow under the pressure. In cases like this, you really need a complete set of solutions that only experienced waterproofers can recommend and set up for you.
One small gap or one small oversight can make a waterproofing system weak. Therefore, probably the most crucial element to make waterproofing last long is the combination of experience and genuine care. You need experts that have the know-how and who will go the extra mile for you. More importantly, you need people who can innovate on the fly to give you nothing but the best.
