Eliminate Dangerous Voids Under Concrete
Voids can form under concrete for numerous reasons, leading to significant problems if left unaddressed. Thankfully, Greenline Services is here to help you fill those voids. The presence of undetected voids beneath slabs and structures can cause them to sink or collapse without warning, posing serious risks of injury, litigation, and even death. Our advanced void repair technologies can safeguard your property and assets from these hazards.
- Before and After
Causes of Voids Under Concrete
While concrete is renowned for its durability, its strength heavily depends on the stability of the surface beneath it. Voids or gaps under concrete can arise from various factors, including:
- Erosion: Water can erode the soil beneath concrete slabs over time, compromising its strength and stability.
- Poor Compaction: Inadequate soil compaction during construction can lead to premature failure of concrete slabs.
- Freeze/Thaw Cycles: Water that infiltrates concrete can freeze, expand, and create gaps when it melts, weakening the soil structure.
- Drought: Extremely dry conditions can cause soil shrinkage, leading to voids under concrete.
- Poor Maintenance: Neglecting to repair concrete cracks allows water to seep in and erode the soil underneath.

The Importance of Concrete Void Filling
Voids under concrete slabs are often hidden from view, making them difficult to detect until significant damage occurs. If you suspect voids beneath your concrete slabs, it’s crucial to address them promptly. Signs of underlying voids include sloping or uneven concrete.
Failing to fill concrete voids can result in several problems:
- Insufficient Support: Concrete slabs without adequate support are prone to cracking, damage, and collapse under heavy loads.
- Machinery Damage: Heavy equipment like forklifts can cause compromised slabs to collapse, leading to costly repairs.
- Safety Hazards: Neglected voids can result in personal injury or death due to collapsing concrete or trip hazards.

- FAQs
Void Filling FAQ
What is void filling?
Void filling is the process of injecting foam or mud to fill gaps beneath concrete. This technique strengthens the subsurface, enhancing the durability and extending the lifespan of concrete slabs.
How do you fill voids under concrete?
Greenline Services utilizes polyurethane foam to fill voids under concrete. Our process involves drilling small holes and injecting the foam, which rapidly spreads and hardens, effectively stabilizing the concrete.
What is the best fill under concrete?
Polyurethane foam is the ideal concrete void filler due to its durability, affordability, and long-lasting performance. It can last for several decades and is also safe for contact with drinking water.
How do you check for voids under concrete?
You can detect voids under concrete using a high-frequency, high-resolution Ground Penetrating Radar (GPR) system. Other methods include observing signs of sloping, checking for breaking corners, and tapping the concrete to listen for a hollow sound, which indicates the presence of voids.
How do you fill deep holes in concrete?
When there are deep holes or gaps under concrete, it is crucial to act quickly. Injecting polyurethane foam into the underlying soil provides a long-term and cost-effective solution, ensuring stability and preventing further damage.
Can sand be used as a fill under concrete?
It is generally not recommended to use sand as a sub-base. Although some may use it as a void filler, it lacks durability and can shift under heavy loads, leading to instability and potential damage.
What causes voids under concrete?
Voids under concrete can arise from several factors, including erosion, poor compaction, drought, inadequate maintenance, and the freeze-thaw cycle.
