SPEC SHEETS FOR EVERY POSTECH PILE
Filter by shaft diameter, helix size, and load rating. Every sheet is the current production specification, reviewed annually against NBC, IBC, and Eurocode updates.
How to Use These Sheets
Spec sheets are organized by shaft diameter and intended application.
Residential piles cover most decks, sunrooms, additions, and sheds. Commercial piles cover light commercial structures, signage, and modular foundations. The Thermal Pile™ is a separate category for frost-sensitive sites across Canada and the Northern US.
Every sheet lists the production geometry, allowable load capacity by soil class, torque rating, and the certification standards the pile meets.
