A leaking basement is a very common issue in homes. Whether your home’s foundation walls are made of poured concrete or masonry, they might show signs of leaking. If you notice that water is coming into your basement through the walls, your foundation is likely experiencing hydrostatic pressure. In this blog, we will cover the common reasons for leaking basement walls and offer nine easy tips to fix them.
Why Your Basement Wall Leaks?
Hydrostatic pressure, a natural force exerted by groundwater against the basement walls and floor, is one of the primary causes of basement leaks. Over time, cracks and gaps in foundations can lead to water leakage.
The clay bowl effect also affects basement walls. During the construction of your home’s foundation and walls, the backfilled soil is looser than the rest of the soil on your property and absorbs more water, putting pressure on the walls.
Since concrete is porous, water can seep inside the foundation walls. Water may also leak into your basement through the cove joint, which is where the walls and floor meet.
How Can a Leaky Basement Wall Affect Your Home’s Foundation?
A leaky basement wall is not only inconvenient but causes significant cosmetic and structural damage to your home, including:
- Structural Damage: Continuous water exposure can weaken concrete and lead to significant foundation damage, which is costly to repair.
- Mold Growth: Damp basements are perfect for mold growth, which can affect a home’s indoor air quality and cause allergies or respiratory problems.
- Damage to Belongings: Water damages furniture, electronics, documents, and other valuables that are stored in your basement.
- Decreased Property Value: Buyers will find your home less appealing if they notice your basement leaking, reducing its market value.
9 Tips to Fix a Leaky Basement Wall
To fix a leak in the basement wall, here are solutions to try:
1. Determine Where the Water is Coming From
If your basement leaks, the first step is to identify the source of the leak. Water enters your basement through the floor joint, walls, windows, and plumbing fixtures. To determine the source of the leak, use a moisture meter or conduct a visual inspection. You must keep an eye out for water stains on the walls and floors, peeling paint, cracks along the wall, crumbling mortar, efflorescence, mold growth, or musty odors.
When it comes to the basement wall, you can inspect these common sources of leaks:
- Cracks: Settlement or frequent ground movement creates stress-induced cracks in basement walls.
- Pipe Passageways: Improperly sealed pipe passageways also serve as an entry point for water.
- Gaps in Grout: Eroded grout lines in masonry walls also establish pathways for water seepage.
2. Install a Dehumidifier
Installing a dehumidifier doesn’t stop basement leaks. However, it controls the moisture levels inside the basement. It’s a good idea to install a dehumidifier as it helps to maintain moisture levels and prevent mold growth.
3. Repair Foundation Cracks
Fill in any wall cracks or gaps. If the cracks are small and thin, use a flexible interior sealant, such as epoxy. When your foundation expands and contracts according to the seasons, the epoxy can shift to accommodate these changes. As a result, epoxy prevents water from entering through even fine cracks.
4. Install an Interior Drainage System
Install a vapor barrier and drain tile for a robust interior drainage system. When water seeps into the basement walls, it hits the vapor barrier and drips down to the drain tile. The drain tile is a perforated pipe laid in a bed of gravel. The pipe collects the water and prevents it from seeping through the cove joint. It also directs water to the sump pit so that it can be redirected away from your home.
5. Install a Sump Pump System
If your basement is prone to seasonal flooding, install a sump pump. A sump pump pumps excess water out of the basement, especially during heavy rain, preventing flooding and making your interior drainage system more effective.
6. Insulate Pipes
Insulate cold water pipes to prevent it from freezing and bursting. You can insulate the hot water pipe to reduce your water usage and bills.
7. Clean Gutters and Downspouts
Clogged gutters and downspouts let water overflow and pool around your foundation walls. If you notice your gutters overflowing, especially when it’s raining, it means it’s time to clean them. Remove all leaves and debris to ensure that your home’s gutters are properly channeled away from water.
8. Divert Water Away From Your Home’s Foundation
Installing a French drain is another effective way to divert water away from your foundation. It is a trench filled with gravel installed around the perimeter of your home.
