Let's delve into the mechanics and discover why Resin Is a game-changer for void filling.


Step 1

Understanding Polyurethane Resin Foam

Before we can fill a void, we need to find it. 

Signs to look out for include uneven ground, cracking surfaces, or that unsettling feeling of sinking.

Step 2


Preparing for Injection

Before we start injecting foam, we need to assess the area. This often involves drilling small holes into the surface above the void. These holes act as entry points for the foam. Don’t worry—it’s not as daunting as it sounds. The holes are small and can be easily patched up afterward.


Step 3

Injecting the Resin

Using specialized equipment, the polyurethane resin foam is injected into the void through the pre-drilled holes. As it’s injected, it starts to expand. Picture a slow-motion balloon filling up with air, but in this case, it’s foam filling up space underground.

Step 4


Watching the Magic Happen As the foam expands, it begins to fill the void, pushing against the surrounding soil and structures. This not only fills the empty space but also compacts the surrounding ground, providing additional stability. The foam hardens quickly, usually within minutes, forming a solid, supportive structure.

A Real-World Example

Let’s say you have concrete that is sinking and uneven because the soil underneath has settled, creating voids. Traditional methods might involve digging up the driveway, refilling the voids, and reconcreting—an expensive and time-consuming process. But with polyurethane resin foam, small holes are drilled, foam is injected, and your concrete slab is stabilized without the need for major reconstruction. 

Benefits Summary

Here’s why people choose resin injection for underpinning;

  • Lightweight and Strong: It doesn’t add significant weight to the ground, preventing further settlement.
  • Durable: Once hardened, it’s incredibly durable and resistant to water and chemicals.
  • Efficient: The process is quick, often completed in a matter of hours, with minimal disruption to the surrounding area.
  • Versatile: It can be used in various settings, from residential lawns to industrial sites.
