Why Voids Form Beneath Properties

Soil Erosion

Water runoff, leaking drains, or underground streams can wash away soil beneath concrete slabs and foundations, creating dangerous voids.

Decomposing Organic Matter

Buried vegetation, tree roots, or organic materials decompose underground, leaving empty spaces where solid ground should be.

Damaged or Collapsed Drains

Broken drainage systems allow water to wash away supporting soil, creating voids along pipe runs beneath buildings.

Mining Subsidence

Historical mining activity creates underground cavities that migrate upward, eventually forming voids beneath surface structures.

Frost Heave Damage

Repeated freeze-thaw cycles can displace soil and create gaps beneath concrete surfaces in susceptible areas.

Construction Vibration

Heavy machinery, pile driving, or demolition work nearby can cause soil compaction and void migration.

Settlement of Made Ground

Previously disturbed ground, infilled land, or reclaimed sites are prone to ongoing settlement and void formation.

Construction Vibration

Heavy machinery, pile driving, or demolition work nearby can cause soil compaction and void migration.

Subsurface Decomposition

Buried organic matter decomposes over time, leaving underground voids that cause settlement and foundation collapse.

Signs You May Have Voids

If you’ve noticed any of these warning signs, void filling could prevent costly structural damage and protect your property investment.

Hollow Sounds

Floors or concrete that sound hollow when tapped or walked upon.

Sinking or Settling Slabs

Concrete surfaces that have noticeably dropped or become uneven.

Cracks in Concrete

Especially cracks that appear suddenly or continue to widen over time.

Gaps at Building Edges

Visible spaces between concrete slabs and building foundations or walls.

Uneven Floor Levels

Interior floors that have developed noticeable slopes or height differences.

Drainage Issues

Water pooling in areas where it didn’t previously, suggesting ground settlement.
