Pile Adapter

A wide range of fixed or adjustable adapters are available to make for an easy and effective connection between the screw pile and your structure.  Whether wood, steel or concrete we are likely to have an adapter that is perfect and for unique projects we can customize an appropriate adapter.

Thermal Insulation

Every Postech Thermal Pile features a uniquely formulated insulation that creates a thermal break at a crucial point on the shaft to keep frost and ice from forming below the frost line and at the base of the pile.  The result is a screw pile with unaparalled protection against movement caused by frost heaving.

Galvanized Steel

Built to last until 2215, Postech Thermal Screw Piles feature cold-rolled and fully galvanized commercial grade Canadian steel from 3 carefully chosen mills. 

Helical Blade

Installed below the frost line, it serves as the load bearer and at the same time provides effective resistance to uplift.  Available in single, double or triple helical designs, Postech Thermal Screw Piles are an effective foundation support as well as anchor.  The number and size of helical blades is determined by both the design loads and soil conditions.  Your local Postech certified installer will guide you in selecting the appropriate Thermal Screw Pile needed for your project.
