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.
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.
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.
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.
Here’s why people choose resin injection for underpinning;
