Do screw piles offer lateral resistance?
Answer: Screw piles are better suited to direct compression and tension applications, but it appreciated that this is not always the case. Intuitively a relatively slim pile shaft (60mm-89mm outside diameter) has poor lateral resistance – we suggest up to 5kN. To overcome this, we manufacture conical extensions as standard which increase lateral resistance up to 10kN. Bespoke conicals can be made if lateral resistances greater than this are required.
