Is your deck built to survive the winter? Frost heave is one of the most destructive forces facing outdoor structures. Caused by seasonal freeze-thaw cycles, frost heave forces upward ground movement that tilts deck posts and leads to severe structural instability.
In this video, learn how Green Shield protects your outdoor living space from shifting soil. Through the Green Shield Proven Process, deck footings are anchored deep into stable soil well beneath the frost line.
Homeowners deserve a beautiful outdoor space that is built to last, staying level, safe, and secure through every season.
