Hollow-bar piles consist of three main components: the pile head, the steel tendon or compression member - including coupler and single-use drill bit - and the grout body.

The steel tendon or compression member is a hollow steel bar with a coarse, cold-rolled round or trapezoidal thread and can therefore be cut or joined at any desired point.

Features:

• National approval pending
• Well suited to transport and assembly conditions as delivered in parts with couplers
• A wide selection of drill bits allows use in a wide range of soil types
• Simple to adapt to required length on site, e.g. with varying geological conditions by using partial sections with couplers
• Excellent bond between SHS-bar and cement mortar thanks to threaded ribs
• Can be closely matched to the required loads thanks to wide range of cross-sections
• Facilitates rapid building progress since drilling, installation and injection of the pile are carried out in a single operation
