Is it compressed lumber to eliminate 'air-pockets' or use of chemicals involved?

Chemicals are used. The lumber is placed in a huge chamber, chemicals are added and the chamber is pressurized to force them into the wood. Two types of chemicals are used. CCA, which is arsenic based and being fazed out. The other chemical is ACQ, which is copper based. You can find more information at your local Lowe's or Home Depot for free.

Pressure treating is a process that forces a chemical preservative deep into the wood. The wood product is placed into a humongous cylindrical holding tank, and the tank is depressurized to remove all air. The tank is then filled with the preservative under high pressure, forcing it deeply into the wood. The tank is then drained and the remaining preservative reused. The wood is removed from the tank and prepared for shipment to your local lumberyard.

I believe it means that the wood has had a preservative injected into the wood under high pressure.
We used some building our deck.
