A rod hole is a small, cone-shaped hole left in poured concrete walls from the metal tie rods used to hold the forms together during construction. Over time, the plastic caps or mortar used to fill them can fail, causing leaks.

How do you fix a leaking basement crack?

We use a low-pressure polyurethane injection system. This fills the crack from the inside all the way to the outside soil, creating a flexible, permanent seal that stops water instantly.

Do you offer a warranty on waterproofing repairs?

Yes. All our crack and rod hole repairs come with a lifetime transferable warranty. If it leaks again, we fix it for free, and this protection passes to the next homeowner.

Why Basement Wall Cracks Form in Michigan

Michigan basements are exposed to freeze–thaw cycles, seasonal soil movement, and groundwater pressure. Over time, poured concrete foundation walls naturally develop vertical or diagonal cracks as the concrete cures, settles, and responds to these environmental stresses. While common, these cracks create a direct path for water intrusion and often lead to recurring basement leaks if not properly sealed.

Our Crack Repair & Waterproofing Process

The Crack Team uses a pressurized, full-depth crack injection system that combines our exclusively formulated TeamSeal® and TeamFlex® products to seal cracks and voids throughout the entire thickness of poured concrete foundation walls. By stopping water at its source—before it enters the basement—this method provides a long-lasting waterproof seal while allowing the repair to flex naturally with seasonal movement.

✓Seals cracks at the source
✓No interior drain systems
✓No exterior excavation
✓Clean installation
✓Minimal disruption

Why Low-Pressure Injection Is the Right Approach for Metro Detroit Homes

For poured concrete foundation wall cracks, low-pressure injection provides the most complete and reliable repair when conditions allow. By using a low-viscosity, hydrophilic polyurethane that enters the crack as a liquid, the material can fully penetrate the entire depth of the wall before expanding to form a watertight seal.

Some systems rely on thicker materials injected under high pressure, which can stop water quickly but may not fully penetrate the crack. Interior drain systems and exterior excavation are designed to manage water after it has entered the basement, not repair the crack itself. Low-pressure injection directly seals the source of the leak, making it the preferred long-term solution for poured concrete foundation walls common throughout Metro Detroit and Michigan’s changing moisture conditions.

Cracked and Leaking I-Beam Pockets

I-beam pockets are cutouts in a poured concrete foundation wall to allow for the installation of I-beam supports. Once the support is in place, concrete is packed around it to connect it to the poured concrete wall. Over time, the concrete may loosen and break the seal, resulting in leakage.

Leaking Rod Holes

The poured concrete for your basement walls were constructed by connecting two forms by rods, usually around 5/8 inch in diameter. Once the concrete sets, the forms and rods are removed, leaving behind numerous small holes in the wall. These holes, commonly referred to as “rod” holes, are typically filled with a small amount of concrete patch during construction to prevent leaks. However, this patchwork is very limited and tends to leak after several years of weather. Recently, we have even noticed builders filling rod holes with air gap filler which is not intended for and will not stop water.

Sill Plate Leaks:

The sill plate is a part of the home’s framing that sits on top of the foundation wall. During construction, a seal is installed between the framing and the concrete foundation wall. However, this seal can fail, especially if the ground or landscaping has been built up above the level of the sill plate.

Basement Crack Repair & Waterproofing: Understanding Vertical Fissures

Finding a crack in your foundation can be stressful, but understanding the right solution is the first step toward a permanent, dry basement. In Metro Detroit, our soil conditions often lead to natural settling, which makes professional crack injection an ideal choice to stop water seepage and prevent future leaks through vertical wall cracks.

How do I know if my basement crack needs professional repair?

While not every small hairline fissure is a structural threat, any crack that shows signs of moisture, dampness, or active leaking should be addressed. Common warning signs in Metro Detroit homes include white powdery residue (efflorescence) or water stains on your poured concrete walls. If you aren't sure, we can often provide a quick assessment from a clear photo to help you decide if Basement Crack Repair & Waterproofing is necessary for your home.

How to Identify Basement Issues Early

Before a small leak becomes a major nuisance, keep an eye out for these common warning signs:

Visible Vertical Fissures: Common up-and-down cracks in poured concrete walls that often signal natural foundation settling or concrete shrinkage.
Efflorescence: A white, powdery mineral deposit on the walls that indicates active basement moisture control issues.
Damp Odors: Musty smells often mean water is seeping through the foundation, even if you can't see the standing water yet.
