Technical Sheets - Extensions

Extensions are essential in projects where the pile needs to be extended to achieve optimal strength and stability at depth. Or when the height of the pile needs to be adjusted to achieve a level foundation support. Postech extensions are manufactured to the same standards as our screw piles and can be simply bolted to the piles for a secure, long-lasting connection. No need for on-site welding.

Extensions

Standard extensions

Extend the length of the screw pile so that they can be installed in a deeper layer of soil with better bearing capacity. Consist of a tube of the same diameter as the pile, coupled with a connection ring that’s reinforced for high torque. Extensions are bolted to the installed pile in the field.
