Timber Piles

Driven timber piles are the most economical solution for deep foundation material. Timber piles are available in sizes from 150mm to 350mm diameter and upward on specific requirement and in length well up to 12m, for longer lengths the poles can be spliced.

Timber piles can be treated to H4, H5 or H6 grade for protection.

Driven timber piles are easy to install, can be cut with a saw and when capped with concrete can last up to 100 years. They can be installed in close proximity.

Application

  • House foundations
