Ground Freezing

Poly-Fusion spent five years on the largest structural excavation using ground freezing as a method of earth support. All piping supply, fusion and installation was provided. The completed excavation had a diameter of 220 feet and extended 125 feet deep into the crown pillar of an existing zinc and nickel mine.





Poly-Fusion also used ground feezing to provide a groundwater barrier around the perimeter of a proposed open pit gold mine. Approximately 2400 freeze and temperature monitoring pipes were installed around the 3.5 kilometer perimeter.
