Classification of pile with respect to type of material[edit] http://en.wikipedia.org/wiki/Deep_foundation

TimberAs the name implies, timber piles are made of wood.

Historically, timber has been a plentiful, locally-available resource in many areas. Today, timber piles are still more affordable than concrete or steel. Compared to other types of piles (steel or concrete), and depending on the source/type of timber, timber piles may not be suitable for heavier loads.

A main consideration regarding timber piles is that they should be protected from rotting above groundwater level. Timber will last for a long time below the groundwater level. For timber to rot, two elements are needed: water and oxygen. Below the groundwater level, oxygen is lacking even though there is ample water. Hence, timber tends to last for a long time below groundwater level. It has been reported that some timber piles used during 16th century in Venice still survive since they were below groundwater level. Timber that is to be used above the water table can be protected from decay and insects by numerous forms of wood preservation using pressure treatment (ACQ, CCA, creosote, etc.).

Splicing timber piles is still quite common and is the easiest of all the piling materials to splice. The normal method for splicing is by driving the leader pile first, driving a steel tube (normally 60–100 cm long, with an internal diameter no smaller than the minimum toe diameter) half its length onto the end of the leader pile. The follower pile is then simply slotted into the other end of the tube and driving continues. The steel tube is simply there to ensure that the two pieces follow each other during driving. If uplift capacity is required, the splice can incorporate bolts, coach screws, spikes or the like to give it the necessary capacity.

什么木头不好说，如果房子有三十年以上的话，应该是用HARDWOOD做BASE的，因为HARDWOOD 种类很多比如KWILA, JARRAH等等。

颜色有点灰白/黑,有丝丝裂缝那种原木,是treated pine 吗? 从颜色和质地能判断是什么木吗?

一般是从木纹判断木种的。

其实对于pile来说要买房没必要太纠结这个pile的木材，因为能被采用作为pile的就这几种，只要做好builder report就好了，还有report会观察有没有borer之类的，没有一般都可以。
