What Are Postech Screw Piles?
Postech screw piles are galvanized steel foundation anchors that are screwed into the ground using specialized hydraulic equipment. Unlike poured concrete footings, screw piles are installed with minimal excavation and are ready to build on immediately.
They feature a helical blade at the base that helps drive the pile deep into the soil while creating a secure hold. Postech piles come with specially formulated insulation system, which helps insulate the pile and prevent frost heaving—a common issue in Canadian climates.
Designed to Adapt: Soil Conditions Are No Obstacle
One of the biggest advantages of Postech screw piles is their ability to perform in virtually any ground type:
🟤 Clay Soil
- Clay expands and contracts with moisture, often leading to movement in concrete footings.
- Postech piles are driven deep below the active layer of clay, where ground conditions remain stable.
🟡 Sandy Soil
- Loose, granular soils like sand don’t always hold traditional footings well.
- The helical blade on a screw pile anchors tightly into these soils, providing strong lateral and vertical support.
⚫ Rocky Soil
- Customized installation techniques allow for secure placement even where boulders or bedrock are present.
🔵 Wet or Marshy Soil
- Waterlogged areas or flood-prone zones are difficult for poured concrete foundations.
- Postech piles displace minimal soil and can be installed without drying the area, staying resistant to movement from water saturation.
🟢 Frost-Susceptible Soil
- In cold climates, soil movement from freeze/thaw cycles can lift and damage footings.
- Postech’s patented interior insulation blocks frost from penetrating the pile, keeping it stable all year long.
Benefits Beyond the Soil
✅ Immediate Load-Bearing Capacity
Unlike concrete, which can take days or weeks to cure, Postech screw piles can support structures as soon as they’re installed.
✅ Minimal Disruption
Installation is quick, clean, and requires no heavy excavation. This is ideal for tight spaces, existing landscaping, or environmentally sensitive areas.
✅ Precision and Consistency
Each pile is installed to engineered specifications using torque monitoring, ensuring consistent performance across every installation.
✅ Eco-Friendly
Because there’s no concrete and minimal soil disruption, Postech is a greener foundation choice with less environmental impact.
