Tunnels

Void Filling Tunnels

Filling in unused tunnels is a critical part of the decommissioning process. Left open, they can pose a variety of safety risks. Unused tunnels pose a safety risk for everyone around them. They can cause sinkholes and other structural damage as the ground above them erodes and collapses. They are also dangerous places for exploration and play, but people still seek out these empty caverns to cause mischief or search for adventure.

Decommissioned tunnels must be filled in as soon as possible to prevent sinkholes, risks to explorers, and other hazards. FillFoam™ is a product offered by ECO FillFoam and is the best option to do so—it's quick-drying and environmentally friendly, making it ideal for filling large spaces with minimal disruption to nearby areas. FillFoam™ is a cost-effective solution for municipalities needing to fill decommissioned tunnels.
