Development

 A great deal of university research and site testing has taken place in the theoretical and practical development of Instant Foundations screw piles. Field results for the performance of the screw piles in sand, clay and rock strata have been used to refine the models.

 Relationships between soil strength parameters, strata density, installation torque and load bearing capacity have been established which provide a quality control method for utilisation in the field. This has resulted in the greatest engineering and consumer confidence in instant screw piles.
