Why Should You Waterproof Your Foundation Walls

Last modified: 2017/09/05 | 2 mins

Are you wondering if you should waterproof your foundations? Trying to figure out what exactly you're supposed to do? is here to tell you everything you need to know about waterproofing your foundations.

Why waterproofing your foundations is very important

Your house needs to be well protected against water and humidity. If not, both elements can cause major damage to the whole structure of the house. Among other things, they can also affect air quality. The ground which surrounds your house contains water and if your foundations aren't watertight, the water may start seeping in.

Even if it leaks in small quantities, over time, not only will the concrete become damaged but you will be at risk for flooding. Spring and Fall are especially problematic, most of all for those who live in an area with major snowfalls. During these periods, your foundations will be to be subject to a lot of hydrostatic pressure.

If there are any cracks or if the concrete is chipping, the foundation walls will not support the added pressure. In these conditions, waterproofing is even more important.

Choose your waterproofing products wisely

Now comes the time to decide which methods and products you are going to use. You may have a hard time selecting the best option, as there are plenty of different techniques out there. When in doubt, talk to a professional contractor. They will be able to give you the best advice according to your specific problems and the type of foundation.

If you feel that you know what you're doing, one piece of advice you should follow is to beware of cheaper products. Oftentimes, it's better to pay a bit more to get a better, more long-lasting result. Foundation specialists will have access to better products than what you can find in hardware stores so that may be another reason to work with a professional.

When done by a professional, waterproofing your foundations will run you between $150 and $300 (per linear foot), with a minimum price of $5000. This includes labor, materials and equipment. Not included in the price is the installation of a foundation drain (french drain).
