Voids under concrete slabs are caused by various things including,

  • Erosion – Excess water around a concrete slab leads to soil erosion and then voids. Two common causes of erosion are drainage issues and leaky plumbing.
  • Soil settlement – Soil settlement is another cause of voids under a slab. Soil needs adequate compaction before you place something heavy on top of it. If it’s not compacted, the soil will compress unevenly after something heavy – like a concrete slab – is placed on it. This, combined with poor drainage, is a sure recipe for void formation. Settlement can also cause problems with drainage.
  • Freeze/thaw cycles – Seasonal temperature changes cause freeze/thaw cycles that contribute to erosion and void formation.
  • Clogged gutters and short downspouts – Excess water under the slab can lead to erosion if it cannot adequately drain off. Two causes of excess moisture are clogged gutters and downspouts that are too short and therefore unable to channel water away from the slab.
  • Drought – Soil will shrink if it dries out, and soil shrinkage often leads to voids. F
  • Hydrostatic pressure – When too much water under the slab can’t drain off, hydrostatic pressure will build up and push against the slab. This can cause it to crack and become unlevel.
  • Poor maintenance – Poor maintenance practices can also cause voids. For example, if you don’t fix cracks in the slab right away, rain will get under the slab and this could lead to erosion.
  • Burrowing critters – Even burrowing animals can contribute to void formation.
