Helical/screw piles: load, soil and traceability

Treat a helical pile as an engineered foundation element: loads, soil, depth, installation torque, corrosion, connection and records must match the assessed system.

VERT / GREEN

Define structure, loads and layout before selecting the pile.

JAUNE / YELLOW

Installation torque and depth do not replace design suited to soil and product.

ROUGE / RED

Random pile selection, uncertified installation or structural load without design: stop before installation.
