In many homes, one of the first times that we notice waterproofing issues is when we have water coming in from the walls. This seepage or foundation wall leak can be due to many different things, but the main reason is usually because of foundation cracks. However, how are these cracks caused? How can they be resolved? Let’s find out!
Usually, foundation wall leaks are caused by cracks in the foundation. This can be due to a multitude of issues. One of the most common is from hydrostatic pressure. Hydrostatic pressure is when soil becomes saturated with water and pushes against the foundation walls. The weight of the soil can cause unnatural pressure on the walls which then causes cracks. These cracks can let in anything from water to pests. Plus, a leaking basement can lead to even worse issues like mold and mildew which can affect your health. Another way cracks can be caused is by tree roots invading the structure. Cracked walls can even be caused by old age or poor initial construction. In any case, cracks are a serious foundation and waterproofing issue that may even lead to bowing walls which are threatening to the stability of your home.
One of the best ways to resolve a foundation wall leak is first to clean up the mess. The water, mold, or mildew needs to be cleaned up before any work can be done on the foundation. We don’t want to trap that mold or mildew behind any encapsulation or inside the walls. So first clean up will be done and any mold will be removed. Next, we will start on the foundation repair. A urethane crack injection is the preferred method of repair. This is because of its lower cost and no need to excavate the foundation wall. Another advantage of the urethane material is that is expands to fill the entire crack, effectively stopping the water on the exterior of the building. However, this material is also flexible so it allows for changes in the seasons. If you have a finished basement, you may want to choose an outside option. There are two typical options for exterior foundation leak repair, a waterproof membrane or a sodium bentonite clay application.
