Building Product Information Sheet

Product: Wooden House Piles

This sheet is produced in compliance with the requirements of the Building (Building Product Information Requirements) Regulations 2022. Under Schedule 1 of those regulations certain information must be disclosed about designated building products (in this case Wooden house piles) to provide building product users with data about how building products contribute to compliance with the Building Code. 

Wooden house piles are used in conjunction with sub floor timber framing systems to elevate constructions (mainly dwellings) from the ground, particularly where the ground is uneven or on a slope. Use on level or flat ground is also applicable.

Experience such as from the Canterbury earthquakes of 2010 and 2011, has shown that piled flooring systems offer enhanced protection against major damage in seismic events and flooding.

Wooden house piles may be round or square sawn.

1 Physical properties: - The standard cross section dimension for sawn house piles is 125mm x 125mm but they may be larger. - The minimum diameter for a round house pile is 140mm except that they may be as small as 120mm diameter within 200mm of either end or may be pointed to facilitate driving into the ground. - The maximum length of a house pile is 3.6m. - Round piles have a straightness requirement and sawn house piles have limitations on permitted warp.

2 Grade: - Timber house piles must be graded to No1 Framing as per NZS3631:1988 New Zealand Timber Grading Rules. - Sawn anchor piles must have their physical properties verified by proof testing conducted in accordance with procedures set out in Appendices A and B of NZS3605. In simple terms the tests involve the application of a load of 3.3 to 4.1 tonnes to the face of a pile for a period of at least 10 seconds without the piece showing signs of distress or permanent damage. - Sawn house piles of Pinus species that are 3.0m or longer must have no less than four growth rings between the pith and the nearest sawn face.

3 Treatment: - All timber house piles must be treated to Hazard class H5 as described and specified in AS/NZS1604.2021 Preservative treated wood-based products
