PierTech Systems has introduced the Heli Max Grouted Pile, a new hybrid foundation system designed to improve load capacity, precision and safety while maintaining the speed and efficiency of helical pile installation.
The Heli Max is a pressure-grouted, full-displacement helical pile that combines features of helical piles, micropiles, drilled displacement piles, and driven piles into a single deep foundation solution. Its design includes a displacement cone and dual-grouting module that create a sealed grout column, reinforcing the bond between steel, grout and soil to enhance both compressive and tensile performance.
Unlike traditional high-capacity foundation systems, the Heli Max installs using a standard excavator with no spoils, low vibration, and minimal noise. The system allows pressure grouting along the pile shaft and lead section simultaneously or as a controlled post-grouting operation. A one-way check valve and displacement cone maintain grout pressure during curing for a consistent grout column.
According to PierTech, the Heli Max provides higher lateral capacity, greater buckling resistance and faster installation compared with auger cast or drilled displacement systems.
