What Is Concrete Honeycombing?

Concrete honeycombing is when areas of your foundation walls, floors, or columns begin to deteriorate, leaving behind coarse, brittle, and pitted surfaces. Honeycombing can appear on both the outside and inside of your concrete. Early signs of honeycombing are usually a cosmetic problem, but letting them worsen can lead to structural and waterproofing issues.

Causes Of Concrete Honeycombing

Leading causes of concrete honeycombing include,

Improper workability of the concrete – Workability is how easily new concrete can be mixed, placed, consolidated, and finished with minimal loss of homogeneity (a balance of components).
Improper balance of components – If there is too much of one component in a concrete mixture, such as water, it could lead to a separation of aggregates and mortar.
Improper vibration – Freshly poured concrete must be vibrated to eliminate any air bubbles or pockets. If this is improperly done or not done at all, it could lead to honeycombing.
Improper pouring – If concrete is poured too high, it could cause the aggregates and mortar to separate.
Improper reinforcing – Too much steel in a foundation wall or floor can prevent the concrete from spreading evenly.

Effects Of Concrete Honeycombing

Honeycombing affects your foundation in various negative ways if you don’t treat it fast.

Water Damage – Honeycombing concrete can allow outside groundwater to seep into your basement or crawl space foundation.
Structural Damage – If left untreated, honeycombing can grow and affect the structural integrity of your foundation walls or columns.
Cosmetic Damage – Honeycombing concrete ruins the look of your concrete walls and lowers the value of your home.
