What Is Concrete Honeycombing & Do You Need To Fix It?

What is concrete honeycombing & can it damage my home?

Walking down the street you may have noticed before concrete on the sidewalk or road that resembles the look of a bee hive. This bumpy condition is often referred to as concrete honeycombing and causes broken bits of rock and stone on the edges of a concrete slab. While it’s not always common, it can be caused by voids in concrete due to the mortar not filling the spaces between coarse particles.

While this may not seem like a big deal, if it’s something you notice happening to the concrete foundation that supports your home, should it be considered a serious issue?

What causes it?

Typically, concrete honeycombing can be caused by a range of factors, but the most common are:

  • Weak compaction, which causes the mortar to fill voids between the coarse aggregate.
  • Holes and gaps in the formwork, which allow mortar to drain out of the concrete.
  • In some cases, the shape, detailing and placement of reinforced compounds can affect compaction.

Can it damage a home?

In general, concrete honeycombing is considered a cosmetic condition that can only be found on the exterior areas of the concrete pour. However, if it is left untreated over a long period of time, it is possible for moisture to penetrate the exposed areas, which could cause serious structural conditions, including concrete cancer. Concrete cancer causes the steel reinforcement to rust from within the concrete layers and begin to push away the concrete surrounding it.

How can this condition be repaired?

While it may not seem necessary to rectify immediately, we recommend getting the issue fixed as soon as possible. The first step requires the affected area to be stripped by removing the layers of honeycomb until suitable concrete is exposed. The area then needs to be cleaned thoroughly by removing all loose aggregate. Then non-shrink grout can be applied after wetting the slab. Lastly, apply texture and color to match the aesthetic finish.
