AUGER BORED PILES - 150MM TO 300MM - DIAMETER

Augered piles are formed using various sized tracked machines which use sectional flight augers to give an open bore.

The final load capacity is dependant on the depth of the pile, the diameter of the bore and the shear strength and bearing strength of the soil. These piles are often formed with a heave sleeve in the top section to alleviate the effects of ground heave common in clay soils. A high slump sulphate resisting concrete is used with full length reinforcement.

Construction of both methods is the same as for foundation bearing piles. Continuous walls are constructed with small gaps between adjacent piles. The size of this space is determined by the nature of the soils.  Auger bored piles have been used on many projects in Norfolk, Suffolk, Essex, Cambridgeshire and the Uk.
