Sump pumps and french drains are excellent tools when dealing with water intrusion problems in your home. One piece of the puzzle that cannot be overlooked is making sure your foundation or basement wall is water tight.
There are multiple ways for foundations to leak. The most common way is for the foundation to crack. This can come from the soil beneath the foundation settling or moving over time. This puts stress on the concrete and results in cracking. Ground water can also erode the dirt that the foundation sits on, leading to more stress and cracking. Concrete also deteriorates over time. Constant water pressure can actually wash out certain minerals that are put into the concrete; making the concrete weaker. Lastly, foundations most commonly leak in between the seam where the foundation sits on the footer. The reason you should waterproof your foundation or basement wall is because you want to stop the root of the problem, not just treat the side effects. The purpose of solving drainage issues is to prevent the water from even entering the crawlspace or basement. If that is unattainable, fluctuating water table for instance, then their are other solutions to be installed.
How to Reinforce and Restore
Waterproofing a foundation takes a lot of careful digging. After the foundation is completely excavated, it is carefully cleaned and inspected. The method Resto Clean applies not only makes the foundation completely water tight, but actually reinforces the existing concrete.
You cannot waterproof a foundation from the inside of the basement or crawlspace. The water pressure is too great and it will only provide a temporary fix to the problem. Resto Clean also installs a french drain around the perimeter of the foundation in order to provide even better drainage. The video below shows the same exact process that Resto Clean uses when waterproofing a foundation or basement.
