Filling an Old Underground Escape Route with PolyLevel in Kennet Square, PA


This historical house in Kennet Square, PA had a large underground tunnel which was once used as an escape route for slaves. 
To keep the structure above it from caving in, the homeowner called DryZone, LLC. to help fill up the large cavity with PolyLEVEL™, a structural-grade polymer foam designed to be used as an alternative to mud jacking. 
This video shows how easy and quick was the process of filling the gap with PolyLEVEL. The structure was secure and supported immediately after the application because PolyLEVEL cures in minutes!
