When it comes to maintaining their homes, homeowners usually pay more attention to the more visible problems, which makes sense. However, it is often those hidden problems that cause more damage. For instance, the foundation is the most important part of your home since it is responsible for providing structural stability. Ironically, there are so many things that can go south when it comes to foundations. In addition, foundation problems are not always that obvious and you won’t notice them unless you are looking for them.
One of the things that can jeopardize the health of your foundation is the clay bowl effect. It causes rainwater to infiltrate the soil around your house and enter your basement. As you surely know, having standing water in your basement is never good news, which is why the clay bowl effect shouldn’t be ignored. But what exactly is this effect and how can you minimize its impact? Let’s take a look.
What Is the Clay Bowl Effect?
When the builders are constructing a building, they need to excavate a certain amount of soil to make room for the building’s foundation. Of course, that hole is never the exact size of the foundation, but a bit larger. After the foundation is complete, a part of the excavated soil is put back to fill in the gaps between the foundation and the earth around it. This soil is called the backfill. Unfortunately, this soil is no longer as dense as it was before the excavation. No matter how hard the builders try to compress it, it will never be as it was, which is a problem. This is when the clay bowl effect appears. Since the soil around the foundation is more porous than it was, every time it rains or there is a flood, water will collect in this artificial water table.
So, how can you know whether you are dealing with a clay bowl effect? It is simple. Just pay attention to the levels of radon gas in your foundation. The clay bowl effect raises the levels of this gas and also creates cracks in your foundation. Another sign of the clay bowl effect is mold growth. Due to the clay bowl effect, humidity levels in the basement will be higher than in the rest of your house. Mold and mildew thrive in dark and moist places, which is why it is important to take measures to keep your basement dry. If the clay bowl effect is causing problems with your foundation, you will also notice dark patches on the basement walls.
Should You Worry About the Clay Bowl Effect?
Unfortunately, the clay bowl effect can cause an array of problems. It can lead to basement leaks, water damage, mold growth, and other issues. Any time there is excess water around your home, your home’s foundation will be compromised.
When rain falls or the snow melts, the excess water saturates the soil around your foundation. Due to hydrostatic pressure, water will infiltrate the basement through the paths of least resistance such as cracks and openings around pipes. Since the concrete walls are porous and can absorb liquid, water can also enter the basement through the foundation walls. In addition, hydrostatic pressure can weaken the joints in the foundation walls.
Another way the clay bowl effect can damage your home is by bowing foundation walls. As mentioned, the backfill soil is not as dense as it was, so it can move around freely. Because of this motion, it exerts stress on the foundation walls. Eventually, the basement walls begin to bow and become far less stable. Due to the clay bowl effect, radon gas will build up in the basement. The rainwater that soaks the soil around your foundation traps the gas which then enters your basement through the cracks.
The clay bowl effect is not a problem you should ignore. It can lead to all kinds of damage and even compromise the structural stability of your home. However, there are several steps you can take to protect your home:
Interior Drainage System
Due to the clay bowl effect, water can saturate the soil around your foundation and enter your basement. Keeping excess water away from your home is one way to protect your foundation. You can do this by installing an interior drainage system. This system is installed along the interior footer of your foundation and its purpose is to collect the excess water and direct it to the sump pump. From there, the water is directed through the discharge line away from your home.
One of the problems the clay bowl effect is responsible for is bowing walls. To keep the walls from shifting any further and even potentially move them back toward their original position, you can install wall anchors. These anchors made of galvanized steel are installed in the ground away from the foundation walls and present the most effective method for repairing severely distressed basement walls.
