Want is a Screw Pile?
A Screw Pile is a foundation pile comprised of high-grade steel pipe segments, joined together and screwed into the ground until a pre-defined bearing capacity is achieved.  A Screw pile can be used anywhere where soil conditions suggest a conventional driven, bored or micro pile should be used, or even in place of conventional concrete footings.

What are the main advantages of a Screw pile over Driven, Bored, or Micro piles?

• quieter to install
• cause negligible subterranean disturbance
• can be installed even in the worst soil conditions
• quicker to install
• can be installed in places where others cannot
• can be removed from the ground when no longer needed

Why have I not heard of Screw piles before?
Screw Piles have been used in the construction industry for more than one hundred years but because high-grade steel was relatively expensive, they were generally only used for foundations where it was impossible to use traditional piles.  Three things have happened to change all of that:  the relative price of high-grade steel has dropped; the relative costs of manpower and concrete have risen; and the complex computer modeling and engineering, required to optimize a design has become fast and affordable.
