Void-filling is the process of filling a sinkhole or cavity with a solid material. FillFoam™ works in using an open-cell foam to fill voids and stabilize the soil around them. This is an essential step for roads and parking lots that need to be repaired after a sinkhole collapse.
FillFoam™ can flow long distances beneath the surface directly from access points, which allows us to access the most difficult areas to repair. Our method is faster, cost-effective, and lighter on equipment than demolition and alternative methods. With FillFoam™ sinkhole void filling, you can avoid heavy trucks and equipment required for using backfill or cement and reduce the labour intensity of completing a sinkhole repair project.
