Rod Holes: Addressing a Common Foundation Issue

Rod holes are created by the forming crew responsible for building your foundation wall. In order to hold the concrete forms together and to prevent bulging from the weight of wet concrete, rods are passed through the forms from one side to the other.


Rod holes are a prevalent concern for homeowners and businesses with poured concrete basements. These small holes arise during construction when tie rods are used to hold forms in place and are then removed after the concrete cures. While builders typically patch the holes, these patches can deteriorate over time, allowing
water to enter the basement.


  » Degraded Patch: The original patch material used during construction may degrade over time, allowing water to seep through.
  » Unsealed Holes: In some cases, the rod holes may not be properly sealed at all, creating a direct entry point for water.


  » Basement Flooding: Unsealed or improperly patched rod holes can lead to water intrusion and potential flooding in your basement.
  » Mold Growth: Excessive moisture from leaking rod holes can create a favorable environment for mold growth, compromising your indoor air quality.
  » Structural Damage: Over time, water ingress through rod holes can weaken the foundation, leading to structural damage.

Identifying Rod Holes:

  » Unfinished Basement: Look for damp areas, water stains (often iron-like), or small indentations on the basement walls.
  » Finished Basement: Locating the leak might be more challenging. You may need to refer to our drywall removal guide.

Compare your findings to:

  » Nickel-sized divots or holes in the wall that you can touch with your finger.
  » Regular spacing: Rod holes are typically spaced at regular intervals along the foundation walls.
