Frost-Shielding Methodology and Demonstration for Shallow Burial of Water and Sewer Utility Lines.
Burying utility lines below the maximum frost penetration depth can be expensive when difficult digging conditions are encountered or where existing obstacles make the desired depth expensive to achieve. Protecting the pipeline from freezing by adding an insulation shield would allow a shallow buria...
