Basement waterproofing begins with identifying and fixing leaks in the foundation wall.

What Are The Common Causes of Foundation Cracks?

Foundation cracks are a common issue caused by shifting, moving, and shrinking foundations. These foundation wall cracks are particularly prevalent in the Chicago area and often lead to water leaks and seepage into basements and crawl spaces.

It's essential to start basement waterproofing by identifying and fixing leaks in the foundation wall of your basement or crawl space.

How can I identify a leaking foundation wall crack?

If you have a finished basement and cannot access the foundation wall, you can step outside and check the exposed foundation wall. If the foundation wall is not exposed, you can use your garden hose to test it. To do this, spray water on the outside of the foundation and observe if water seeps into the interior. It may take a few minutes for the water to appear. If you notice water seeping from the interior, you have two options for repair: epoxy injection from the inside or waterproofing membrane installation from the outside.

Effective Methods for Repairing a Leaking Foundation Wall Crack.

Injecting epoxy into foundation cracks is a reliable method for repairing leaks. This process welds the concrete back together, restoring the walls' structural integrity.

How do you fix a crack in a foundation from the outside?

If you face water leakage and seepage problems in your finished basement due to foundation cracks or other weak spots, epoxy injection may not be a suitable solution. In such cases, it is recommended to use a unique repair method that involves applying an exterior waterproofing membrane. This method can help prevent seepage and leakage, ensuring your basement stays dry and free from water damage.
