BU560 Pile foundations (2013)

The function of a foundation is to provide resistance to the vertical and horizontal loads acting on a building by transferring those forces to the ground. This bulletin explains the requirements of NZS 3604:2011 Timber-framed buildings for pile foundation systems and should be read in conjunction with that document.

This bulletin updates and replaces Bulletin 399 Timber pile foundations. 

The bulletin covers:

• foundation systems
• pile foundations, including pile footings and concrete encasement, ordinary piles, driven timber piles, driven timber cantilevered piles, braced pile systems and anchor piles
• fixings and durability.
