A frequent comment I hear from clients is the way crack repairs look after completion. They see the smeared on epoxy bonder with unsightly injection ports leave the repair looking messy. We see it too! While the products we use offer a Lifetime Warranty and we know they work, I agree that the final product is often less that attractive for crack repairs. This can also cause concern for potential home buyers who see this as a foundation issue and not a simple crack that was repaired and the lifetime warrantee transfers to them. That’s where we step in.

Part of the process for diagnosing seepage in a client’s home is walking the perimeter of the home with the homeowner noting the location of cracks in the foundation. Look very closely at the picture to the left. Notice the vertical crack directly above the work area? These can be difficult to spot but our Waterproofing Experts have a very keen eye. Many times, these cracks correspond with the area of seepage in the basement. Your Midwest Waterproofing Expert may also run a hose to determine if the crack is the source of the seepage.
In some situations, such as with a block foundation, Sodium Bentonite is not an option. Your Waterproofing Expert will explain the reasons and offer alternatives.
If the crack is clearly visible like in the photo above and is free of obstructions, The Midwest Waterproofing Expert may recommend a process called a “post hole dig” repair using Sodium Bentonite as an alternative to an epoxy/urethane injection from the inside
Sodium Bentonite is an effective, low-cost methods of sealing foundation cracks from the exterior. Also, it is environmentally friendly because it contains no toxins. Perfect for clients with pets and children
Crystal Lake and the surrounding area has a particularly good soil for using Sodium Bentonite called Crystal Lake silt loam.
How Do Sodium Bentonite Repairs Work?
To repair a foundation wall crack using sodium bentonite, the installer digs a small hole against the foundation using a post hole digger. He digs down to the bottom of the foundation to the footing, exposing the entire crack. The hole is then filled nearly to the top with Sodium Bentonite and is covered with soil and whatever landscaping was removed so there is virtually no sign of the repair. The installer may use a small amount of membrane material or epoxy to seal the crack that is exposed above ground.
The dry sodium bentonite absorbs water from the ground which causes it to expand dramatically. This causes the expanding Bentonite to ooze into the crack from top to bottom causing a seal that is warrantied for a lifetime. If the soil is extremely dry, the installer may add a little water to start the process.
Because sodium bentonite is applied from the exterior of the foundation, it is an ideal choice when the crack is not accessible from the inside because the basement has been finished or there are other obstructions such as utilities.
Sodium Bentonite cannot be used on cracks in corners or when there is a permanent obstruction such as a cement porch, blocking access to the crack. However, if a patio, sidewalk or driveway covers the ground next to the foundation, we can cut out the paving material and replace it afterward. We can also dismantle decks or porches to gain access then rebuild it afterwards.

Poured foundation foundations are one of the most common and durable types of foundations used to support buildings. They are used because they are durable, easy to construct and take less time to build than a masonry foundation wall. While a poured concrete foundation is very strong and durable, it can have many issues as well. The most common issue is with cracks that can leak water into a crawlspace or basement.
These cracks can occur due to conditions when the concrete is poured, soil conditions around the foundation as well the shape of the foundation itself. Typical foundation cracks, under 1/8” in thickness are expected, considered normal and not a major cause for structural repair. They can, however, be a source for water intrusion into the basement or crawlspace and should be fixed, whether actively leaking or not. It is our experience that an existing foundation crack will eventually leak at some point.
Diagnosing foundation cracks is pretty straightforward. In the case of an unfinished basement or crawlspace, they are easily seen because the foundation wall is exposed. In the case of a finished basement, cracks can be identified by finding the first point of entry into the basement and looking at the exterior of the building. Foundation cracks are predictable in that they almost always follow a relatively vertical path from the bottom of the foundation wall to the top and can be seen from the exterior where the foundation wall is visible above grade.
How to Repair Concrete Foundation Wall Cracks
If the basement or crawlspace foundation walls are accessible, a urethane crack injection is the preferred method of repair due to its high success rate and relatively low cost. 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. Urethane crack repairs, once cured, remain slightly flexible as well so seasonal movement of the foundation wall caused by expanding soil conditions and frost do not compromise the repair.
If the basement space is finished, an exterior option may be preferred if you do not want to cut open the wall to expose the crack or if mechanical equipment like furnaces and water heaters are in the way. There are two typical options for exterior crack repair, a waterproof membrane or a sodium bentonite clay application. Both work exceptionally well, which one is best for you situation depends on a few factors.
Our staff, with their years of experience, can help determine which crack repair method is right for your situation. If you think you have a foundation crack, contact Midwest Waterproofing for a free consultation.
