The Hidden Dangers of Voids Under Structures

The Hidden Dangers of Voids Under Structures

Voids forming below structures probably isn't something you think about too often. While they may not be a common issue in Canada, voids are not as rare as you might think. Some voids present themselves as sinkholes and are pretty noticeable once they form. But sometimes voids form below foundation slabs, making them harder to notice and much more dangerous. As a homeowner, property manager or construction professional, you might have heard about the importance of filling voids under structures. But do you know what voids are, how they form and why they can be dangerous? In this blog post, we'll look at the hidden dangers of voids under structures and how FillFoam™ Canada can help you mitigate the risks. Read on to learn more!

What Causes Voids to Form Under Structures?

Voids under structures are empty spaces that occur between the foundation and the soil. Voids form beneath structures due to various factors, including natural settlement, poor construction practices, or external forces such as excavation or grading. When the soil beneath a structure becomes uneven or unstable, empty spaces can form, creating voids. These voids can range from small gaps to larger caverns and can occur anywhere under the structure. Voids can be a serious problem as they can lead to uneven settling of the foundation, causing structural damage (possibly leading to eventual collapse), moisture and water damage, and pest infestation. Filling voids as soon as they're detected is essential to prevent these hazards from occurring.

Why are Voids Dangerous?

Voids under structures can cause many problems that can be expensive and hazardous. Voids under structures can pose serious risks to the safety and stability of the building and sometimes create health risks to people using the building. Some of the hazards that voids can create are:

  1. Structural Damage: Voids below structures can cause uneven settling of the foundation, leading to cracks in walls, floors, and ceilings. In extreme cases, voids can even cause the structure to collapse.
  2. Moisture and Water Damage: Voids under structures can allow moisture and water to seep into the building, causing damage to the foundation, walls, and floors. This can lead to mould growth, which can be a health hazard for occupants. 
  3. Pest Infestation: Voids under structures can provide a home for pests such as rodents, termites, and ants, which can cause damage to the structure and pose health risks.
