Please see Wikipedia ( Wood Preservatives ) this will totally explain The various chemical Types used. This is a very in-debth article. Below a brief explanation of wood preservatives.
Chemical Preservatives-
Timber or lumber that is treated with a preservative generally have it applied through vacuum and/or pressure treatment. The preservatives used to pressure-treat timber are classified as pesticides. Treating timber provides long-term resistance to organisms that cause deterioration. If it is applied correctly, it extends the productive life of timber by five to ten times. If left untreated, wood that is exposed to moisture or soil for sustained periods of time will become weakened by various types of fungi, bacteria or insects.
Chemical preservatives can be classified into three broad categories: Water-borne salts, Oil-borne preservatives, and Light Organic Solvent Preservatives (LOSPs). These are discussed in more detail below.

Metal Framing or Precast Concrete , yes you read correct, I have seen some Prefab Crete houses and plumbed many Metal Framed Houses, Timber is about a waste of meterials and resources. It adds undue weight, and is not a structurally effecient as Metal Frames are. Over 20 years, Termites and other natural elements will not do any damage to properly treated metal or untreated crete, wood rots,weakens, and bugs like to eat it.

Yes. You can buy treated wood at any large home improvement store. The treatment deters various pests, including termites.

Try getting some Cyphers or Cider. Little expensive thou even if you can find it. Bugs hate this stuff and it will last a hundred years. Try looking for real old buildings begging torn down. Their foundation timbers are the best. You'll probably need a chain-saw to cut them.

Termites, sometimes known as white ants, are a group of social insects usually classified at the taxonomic rank of order Isoptera. (This has been challenged by recent research, see taxonomy below.) Termites usually prefer to feed on dead plant material, generally in the form of wood, leaf litter, or soil, and about 10% of the 4,000 odd species (about 2,600 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests. Termites are major detrivores, particularly in the subtropical and tropical regions, and their recycling of wood and other plant matter is of considerable ecological importance.
As social insects, termites live in colonies that, at maturity, number from several hundred to several million individuals. They are a prime example of decentralised, self-organised systems using swarm intelligence and use this cooperation to exploit food sources and environments that could not be available to any single insect acting alone. A typical colony contains nymphs (semi-mature young), workers, soldiers, and reproductive individuals of both genders, sometimes containing several egg-laying queens.
Wood preservation
All measures that are taken to ensure a long life of wood fall under the definition wood preservation (timber treatment). Apart from structural wood preservation measures, there are a number of different (chemical) preservatives and processes (also known as timber treatment or lumber treatment) that can extend the life of wood, timber, wood structures or engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungus.
Avoiding termite troubles
Precautions:
Avoiding contact of susceptible timber with ground by using termite-resistant concrete, steel or masonry foundation with appropriate barriers. Even so, termites are able to bridge these with shelter tubes, and it has been known for termites to chew through piping made of soft plastics and even lead to exploit moisture. In general, new buildings should be constructed with embedded physical termite barriers so that there are no easy means for termites to gain concealed entry. While barriers of poisoned soil have been in general use since the 1970s, it is preferable that these be used only for existing buildings without effective physical barriers.
The intent of termite barriers (whether physical, poisoned soil, or some of the new poisoned plastics) is to prevent the termites from gaining unseen access to structures. In most instances, termites attempting to enter a barriered building will be forced into the less favourable approach of building shelter tubes up the outside walls and thus they be clearly visible both to the building occupants and a range of predators. Regular inspection by a competent (trained and experienced) inspector is the best defence
Timber treatment.
Use of timber that is naturally resistant to termites such as Canarium australianum (Turpentine Tree), Callitris glaucophylla (White Cypress), or one of the Sequoias. Note that there is no tree species whose every individual tree yields only timbers that are immune to termite damage, so that even with well known termite-resistant timber types, there will occasionally be pieces that are attacked.
When termites have already penetrated a building, the first action is usually to destroy the colony with insecticides before removing the termites' means of access and fixing the problems that encouraged them in the first place. Baits (feeder stations) with small quantities of disruptive insect hormones or other very slow acting toxins have become the preferred least-toxic management tool in most western countries. This has replaced the dusting of toxins direct into termite tunnels which had been widely done since the early 1930s (originating in Australia). The main dust toxicants have been the inorganic metallic poison arsenic trioxide, insect growth regulators (hormones) such as Triflumuron and, more recently, fipronil. Blowing dusts into termite workings is a highly skilled process. All these slow-acting poisons can be distributed by the workers for considerable periods (hours to weeks) before any symptoms occur and are capable of destroying the entire colony. More modern variations include chlorfluazuron, Diflubenzuron, hexaflumuron, and Novaflumuron as bait toxicants and fipronil and imidacloprid as soil poisons. Soil poisons are the least-preferred method of control as this requires much larger doses of toxin and results in uncontrollable release to the environment.

There is a new treatment that embeds tiny speakers in the wood connected to a common stereo system that plays heavy metal all day and all night and drives the little buggers crazy and they leave.
Very efficient!

You can buy treated lumber. I use copper/green if it is in contact with dirt. You can soak it or paint it on.
